The difference between portable cord styles SOOW, SEOOW, and STOW Portable Cord (and their J – “Junior” versions SJOOW, SJEOOW, and SJTOW)

Choosing which portable cord to use can sometimes be a confusing task. There are several different types and levels to pick from, and they are not always advertised with the options comparing one-another. Listed below are some templates showing the differences between each type.

First, let’s take note of the similarities: each of these multi-conductor power cables can be used in a variety of applications that require wiring with superior flexibility and durability such as portable tools and equipment, portable appliances, small motors, and associated machinery.

Types of SO Portable Cord & Their Unique Properties


“SO” is the most common portable cord. It is made with a rubber jacket, making it known for it’s abrasion and heat resistance. All while boasting a 600 volt rating for continuous operation.

Heat Shrink Tubing – Shelf Life Announcement (QPL M23053)

With the release of the new 23053 QPL in July of 2018 product shelf life was changed to dimensional life. This change means that shelf life is no longer a valid measurement of the products usefulness but it is now measured dimensionally.

The new QPL standard further clarifies that tubing may be used beyond 12 years provided the dimensions still meet the specification, eliminating the need to scrap or return tubing. Heat shrink tubing under M23053 does not expire, the standard calls for validation against the standard prior to use.

This eliminates the need to calculate percent of shelf life. If the dimension falls within QPL spec then the product qualifies and is good.

Below is a copy of the section in the QPL which covers dimensional life.

If you have existing tubing that is in question, Silver State would be happy to help confirm the dimensional life of it with you.

Should you have any questions please let us know,

Nexans (Elm City, NC. Plant) closing

Effective, June 30th, 2016 the Nexans manufacturing plant in Elm City, North Carolina, will be closing.

Nexans manufactures aerospace wire and cable: AS22759 and M27500 products. A few months prior, they also announced they would not be producing AS81044 style wire.

Rest assured though. We purchase wire and cable from multiple QPL approved manufacturers to avoid events such as this causing drastic issues with the supply of mil-aero products.  We are confident that our existing supply chain will be able to support the demands where Nexans was included.

If for some reason, Nexans was your preferred manufacturer for any wire or cable products, we would be happy to discuss a solution with you and your engineering, production, and quality teams.

Thank you for your continued business, and have a great weekend!

14 Ways to be more positive at work

  1. During The Commute

Listen to audio books, podcasts, or inspirational music on your commute both to, and from your workplace. This will help you get ready for the day, as well as unwind on your way home.

  1. Arrive Early

Arrive early and focus on the tasks required for the day. Who knows, you might even get done early and have time to get prepared for your next tasks in line.

  1. Break Times

Use this time to celebrate your achievements so far, or possibly re-focus your day. Try to avoid using your break as time to get caught up.

  1. “Meeting” Options

Walking meetings help focus. Maybe not all can be in an extra-curricular environment, but one meeting like this a day could help. Also, try to leave any meeting with clear and achievable objectives.

  1. Health & Well Being

Exercise is proven to reduce stress and the resulting feel good factor can boost your productivity, while leaving you in a healthy mindset. Add some quick calisthenics to your day to keep your chi in the right place.

  1. Pace Yourself

Rushing tasks will create more errors that are inevitably more work fixing in the long run. This doesn’t mean you should slow down. Find your tempo and try to stick with it throughout the day.

  1. Support

Share your achievements with others and support their work as well. Team building is the key to a successful work group.

  1. Be Positive

Infuse genuine, positive emotions into your work and colleagues. Enjoy the contagious nature.

  1. Compassion

Remain compassionate to negative colleagues. People are usually negative for a reason. Perhaps they need to see or hear your good attitude to get out of a slump.

  1. Collaboration

Never be afraid to ask for help. Collaborate with others to achieve mutual goals.

  1. Office Politics

Don’t get bogged down with office politics. Focus on your tasks and what is needed of you.

  1. Boring Jobs

Bite the bullet and face the mind numbing tasks head on. This will get you through them and on to the things you like doing most.

  1. Constructive Criticism

Understand any criticism aimed at you and use the feedback to improve you own work. A winning team has a coach or coaches who critique their players as much as possible.

  1. Adapt

Business changes and you must adapt in order to survive. Make sure you are open and adaptable rather than resisting change. Better yet, stay ahead of the curve and keep an eye and ear on what changes may be coming. You could even talk about it at your next meeting.

Last of all, “Good job!”

To our valued Customers,

Please be advised Sumitomo Electric Interconnect Products, Inc. will cease manufacturing all “SM” heat shrink tubing products effective 12/31/15. Don’t worry, the “SM-3” tubing (used  on the model III and IV print systems) will be readily available for years to come.

We understand this decision may have an impact on your business and therefore have created the following FAQ’s to help you make internal inventory changes and final purchasing decisions. Please note the following important dates and plan accordingly.

Last Time Buy – 12/31/2015
Last Ship Date – 3/31/2016
(These dates are for SM tubing only, Not SM-3 tubing)

Why the change?
“SM” heat shrink tubing products are compatible only with SumiMark I and II Marking Systems. Sumitomo (SEIP) has not supported these systems for many years. In addition, a key component required for manufacturing of the SM heat shrink tubing products has become obsolete.

Which tubing part numbers are affected?
All part numbers with a SM preceding the product description. Example-SM12, 1/8, WHITE, SPL. This includes all SM12, SM23, SM24 and SM60 product sizes and colors.

Which SumiMark Marking Systems are affected?
Only SumiMark I and II Marking System models will be affected by this change and will effectively become non-operational due to this change. SumiMark III and IV Marking System models will not be affected.

What are my replacement options?
We encourage all customers using SM tubing products to upgrade to the latest SumiMark IV 300 DPI Marking System. This new system is compatible with SM3 heat shrink tubing products and utilizes our new Sumilabel software. SM3 tubing is a direct replacement to SM tubing. However, SM3 tubing cannot be used with SumiMark I and II Marking Systems.

Please don’t dispair, we are offering a special discounted cost for all customers who have a model I or II print system looking to upgrade. Contact with the keyword, “Sumimark-one” for the special pricing.

Important Note: This change does NOT affect SM3 heat shrink products.

If you have further questions regarding this notice, please contact your Silver State Wire & Cable team member at (775) 356-8969, or via email at

Thank you for your continued support as a customer!

Cable Tie Mounts: Rubber or Acrylic adhesive?


When it comes to adhesive-backed cable tie mounts, your decision comes down to rubber adhesives or acrylic adhesives. This is when it is best to know the pros and cons of both adhesive types. Adhesives types are differentiated by combining specific chemicals, elements and additives that give the product a distinctive bond. The strength of the adhesive relies on how strong the adhesive is itself. It is not necessarily true that one adhesive type is better than any other type, but one may suit your application better than another. This to consider are:  Materials being used, temperature, and the environment of the application.

Rubber Adhesives

Rubber adhesives will give you a higher adhesion when compared to acrylic adhesives. The rubber adhesive will bond with many different material types and are usable in most adhesion situations. Rubber has a very fast adhesion time and the bond forms much faster than with acrylic adhesives. By using a rubber adhesive, you will get a superior initial adhesion between your materials. However, it may not offer the most durable adhesion over time. This is because rubber is susceptible to UV exposure. Elevated temperatures will also break down the adhesive over time. Rubber adhesives have the lowest temperature resistance of any adhesive, providing the best adhesion indoors where there is only a light fluctuation in temperature changes. Rubber adhesives have a superior bond to plastics over acrylic adhesives and cost less than acrylics.

Acrylic Adhesives

Acrylic adhesives are preferred on items such as wood, metal, outdoor materials, glass and waterproof items. Acrylic adhesives are more versatile than rubber adhesives and provide more features than rubber adhesives such as being waterproof and unyielding against the elements. Acrylic adhesives are able to stand up to UV exposure where rubber adhesives are not. As well, acrylic can withstand higher and lower temperatures and perform better than rubber adhesives when exposed to chemicals. The consistency over time of acrylics is one of its strong points. The durability and longevity will be greater with an acrylic adhesive than with rubber. Acrylic adhesives do not bond immediately as with rubber. The acrylic will take around 24 hours to set, improving the bond as it sets. Therefore, acrylics will not give you the aggressive adhesion as soon as rubber would, but the bond of acrylic is more sustainable over time.

Deciding between a rubber and acrylic adhesive should not be a difficult choice. You just need to take into account the materials you plan to use and where the project will be located. If you are using a plastic material or if the project will remain indoors a rubber adhesive will provide better cost efficiency and bond much faster than an acrylic. When creating a project that will be outside, exposed to UV or exposed to temperature changes, an acrylic adhesive will provide the best durability and longevity.

AMS-DTL-23053 (M23053) has a new QPL approaching


With a new QPL being approved for the heat shrink tubing market, there are several changes that will be happening in the near future. To start, all tubing built to military grade M23053 will have to be tested and certified by an approved QPL (Qualified Provider’s List) manufacturer.  Unlike the historical status of only requiring a “First Article Test Report” for acceptance.

The change was requested by several large military and aerospace end users who, along with manufacturers and various government entities, have a strong influence upon industry specifications within the SAE Standards Group. The change was supported and facilitated by SAE (AMS-DTL-23053), with the details and implementation being carried out through NAVAIR.

End users have long complained that there are too many low quality substandard products on the market that, despite being claimed as meeting the requirements of the current AMS-DTL-23053, fall short in any number of requirements, depending on the product and source. QPL approval was determined by SAE members to be the best remedy to eliminate such products from the supply chain and instill confidence in end users that they are receiving only the highest quality products for their often critical applications. Within the coming months, SAE AMS-DTL-23053 will be replaced with the new SAE-AS23053 requiring QPL approval. If you are new to QPL or would like to view existing QPL’s on NAVAIR’s website.

Like other QPL items, AS23053 will be on a 3 year review and retention of qualification cycle. Typically, re-qualification is much simpler and quicker than the initial qualification. As an authorized distributor of Sumitube® and Sumitomo® products, this will have little or no effect upon Silver State Wire & Cable.
