Techflex H2N0.19BK.5 2:1 Polyolefin Heatshrink Tubing, 3/16" Diameter, Black

For installers who need a fast, professional finish on cable runs, the Techflex H2N0.19BK.5 polyolefin heatshrink tubing delivers dependable protection and neat terminations. This cable sleeve uses a 2:1 shrink ratio to provide controlled contraction over splices and inline connectors while shrinking reliably at 194°F to a 3/16 in finished diameter. The flame‑retardant material and Mil‑I‑23053/5 compliance reduce fire risk and meet expectations for security and surveillance deployments.

Designed for demanding environments, the tubing resists common automotive and industrial chemicals so monitoring, networking and security cabling stays protected and maintenance intervals are extended. Installers benefit from lower labor time and consistent results across rack, conduit and field applications. Use Techflex heatshrink tubing to improve cable management, strain relief and weatherproofing on cameras, sensors, access control, and network terminations.
