Bentley harris expando hr tw 1" expandable sleeve 500'
Bentley Harris Expando HR TW 1" Expandable Sleeve 500' New!!!
Brand New US Government Surplus. NSN# 5970015212350
This expandable sleeve is perfect for use in aviation, racing, or any other application that requires fire resistance, abrasion resistance, and chemical resistance. The TW denotes that this sleeve is a "Tight Weave". This was used by the government in the Viking S-3B and Orion P-3 Aircraft. This size roll retails for $2000.00!!!! See below for more detail on this.
Low temperature flexibility to -70 C
Does not trap heat or humidity
Self-fitting over many shapes and sizes
Bentley-Harris Expando HR TW is a tough, lightweight product of tightweave design used to overlseeve and protect cable assemblies, hoses and wire harnesses. Made of braided Halar Thermoplastic Monofilaments, Expando HR TW increases cut-through strength and abrasion resistance of electrical and thermal insulating surfaces. It is UL recognized as VW-1 component. It is self-extinguishing.
What is Halar braided sleeving?
Expandable braided sleeving is very similar to those "Chinese Finger Cuffs" that we've all gotten our fingers stuck in.. When you push the end back, the sleeving expands to go over wires easily, and then when you let go, the sleeving comes back to its original diameter (or the diameter of your wire harness or bundle, whichever is larger).
Ethylene-Chlorotrifluoroethylene (E-CTFE) is sold under the tradename Halar. It is a highly chemical resistant material with excellent thermal stability, high moisture resistance, and very low outgassing. Because of its low smoke generation during a fire, it has been found suitable for plenum applications. Halar has also been approved by NASA for use in the space program due to its low outgassing.
Halar Braided Sleeving is used in aerospace, military, fiber optic, and construction applications because of its high fire retradancy, low smoke generation, and low outgassing properties. Halar is a very cost effective alternative to Teflon because of these properties, and its high temperature resistance.
Features of Halar Braided Sleeving:
* Made from 0.011" (11 mil) Halar (E-CTFE) Ethylene-Chlorotrifluoroethylene copolymer monofilament Identified by a single contrasting tracer that wraps around the sleeve in a spiral fashion.
* Chemically inert, thermally stable
* Superior chemical, gas and moisture resistance
* Continuous temperature rating 150 C
* Plenum rated material UL2024 (formerly UL910) and NFPA262
* Abrasion and cut resistant
* Low out-gassing, suitable for plenum applications
* Limiting Oxygen index (LOI): 64%
* Excellent cut through and abrasion resistance
* Continuous use temperature of -70 C to 150 C (-103 F to 302 F)
* Melt temperature of 240 C (464 F)
* Expands up to three times its resting diameter
* Registered in the NASA database for low outgassing
