Allied Encyclopedia: M23053 Heat Shrink Tubing

What is M23053 Heat Shrink Tubing?

M23053 is heat shrink tubing that is used to overall increase the durability of wire and cable. This specific spec is rated to military standards and can be used for military applications. Below this post will discuss some of the specific military lines of M23053 that Allied carries.

M23053 tubing is used to protect wire and cable from external damages. These include chemicals, water, corrosion, and surface abrasion. In addition to protection, heat shrink tubing is also flexible and offers extreme heat resistance. The tubing shrinks to a predetermined size/ratio when heat is applied.

This heat shrink tubing can can be made of various materials. Some of the most popular materials of M23053 heat shrink tubing are Polyolefin, Ethylene-Tetrafluoroethylene (ETFE), Polytetrafluoroethylene(PTFE), Neoprene, Polyvinylidene Fluoride (PVDF), Kynar, and PVC.

M23053 Applications

Heat shrink tubing can be used in a variety of applications. The most common uses for heat shrink tubing are strain relief, wire bundling, electrical insulation, mechanical protection, environmental protection, and component identification. Heat shrink tubing can also be used for repairs, either temporary or permanent. Different types of heat shrink tubing has different shrink ratios to ensure the proper fit for your application. There are options such as 2:1, 3:1 and 4:1 Your application will determine which shrink ratio to use.

Mil Spec Tubing Options

M23053 is rated to military standards and can be used in military specific applications. Some of the most common M23053 slants are /5 and /6, /11, /13, and Kynar /8.

M23053/5 and M23053/6 are Polyolefin heat shrink tubing. These two slants have excellent resistance to water, fungus and UV light. It can be used in applications for bundling, insulation and protection, water and dust proofing, and shock protection. Shrink ratios for this tubing range from 2:1 to 4:1.

M23053/11 is FEP heat shrink tubing. This slant boasts high heat and non stick components which allows it to make a tight seal around components. It can be used in applications that require excellent chemical resistance, as well as high heat situations. The shrink ration is 1, 3:1.

M23053/13 is Viton heat shrink tubing. This slant is ideal for use where high flexibility is needed in either low or high temperatures. It is also good for use where protection from abrasion, fuels, acids, and solvents are present. The shrink ratio for Viton heat shrink is 2:1.

M23053/8 is Kynar heat shrink tubing. This slant is a semi-rigid and flame retardant, Polyvinylidene Fluoride thin wall tubing. It has great cut through, abrasion, and heat resistance properties. M23053/8 is used for jacketing components, fuse coverings, or where strain relief is needed. The properties of this Kynar tubing allow it to be bent, flexed, or twisted without using its mechanical or electrical strength. It has a 2:1 shrink ratio.

M23053 Heat Shrink Tubing to Require QPL Listing

Changes are in store for the heat-shrinkable tubing industry; M23053 Mil-Spec grade tubing will require a QPL Listing, in addition to its original “First Article Test Report” requirement.

Over the years there have been many complaints about the quality, or lack thereof, within the AMS-DTL-23053 approval.  Many end users have criticized the amount of low quality products which claim to meet the requirements of the current AMS-DTL-23053 but prove inadequate, and so the movement to convert M23053 to a more stringent code began.

The change is finally being implemented after several large military and aerospace end users requested the QPL, many of which have a strong influence upon industry specs within the SAE Standards Group.  While the SAE group facilitated the change, the NAVAIR organization is responsible for the actual execution.

SAE members decided a QPL was the best solution to eradicate substandard products and to ensure that the products which meet these standards are premium quality only.  A QPL, or Qualified Producers List, is administered and maintained through U.S. Government agencies.   Many items on the QPL are required to perform in rigorous and critical applications, so only the best will suffice.

Within the next month or two, SAE-AMS-DTL-23053 will be replaced with the new SAE-AS23053 requiring QPL.  All QPL items, including AS25053, must go through a 3 year review and retention of qualification cycle.

M23053 Mil-Spec heat shrink tubing increases the durability of a wire and protects it from outside elements, and a QPL listing will ensure only the best quality for your applications. Although this additional QPL requirement only applies to M23053 Mil-spec tubing, be sure to check out Allied’s large selection of heat-shrink tubing to find the ideal product for your application.
