Series 77 heatshrink boots
HEATSHRINK BOOTS
Heatshrink boots provide strain relief and environmental protection. Shape-memory polymer
returns to as-molded shape when heat is applied. Use with 310-045 composite shrink boot
adapter. Boot lip fits adapter groove for precise fit. Semi-rigid high performance elastomer
resists high temperature and withstands exposure to petroleum-based fluids and fuels. Also
available with non-halogenated flame-retardant polyolefin for use where limited fire hazard
is required.

combines excellent resistance to fuels, oils and solvents with superior performance at
Adhesive
extreme temperatures. Material meets the requirements of VG95343 Type 6, BSG 19ꢀ-5-
DE, EN62329-102 and SAE AS525ꢀ Type H. These boots are recommended for demanding
applications such as military vehicles and petrochemical exploration.
Zero Halogen Polyolefin -30°C to +135°C. Low Smoke Zero Halogen (LSZH) polyolefin
boots meet low smoke and toxicity requirements of shipboard, transit and aircraft systems.
Oxygen index greater than 30%, smoke index less than 20, and toxicity index under 3 per
100 grams. Material meets requirements of NAVSEA 5617649, VG95343 Part 29, BSG 19ꢀ-
5-DF, EN62329-101 and SAE AS525ꢀ Type G. Good resistance to oils, fuels and solvents.
Heat-shrink boots are not watertight
unless equipped with pre-coated
or user-installed adhesives. When
heat is applied to the boot, the
adhesive melts and fixes the boot
to the adapter and cable jacket to
provide the necessary sealing as
well as mechanical strain-relief. For
maximum performance Glenair
recommends Type U user-installed
two-part epoxy adhesive which
offers reduced boot installation time
and easier installation. Pre-coated
boots require additional care to
install because the boot must be
heated sufficiently to activate the
epoxy, at the risk of overheating the
overall assembly. A single 50 ml duo
syringe can coat many boots. The
duo syringe can be re-capped for
re-use. Inexpensive mixing nozzles
must be discarded after each use.
NOTE: Glenair highꢀperformance
two part epoxy meets VG95343
part 15.
