Thomas & Betts HSC2-20 – Frequently Asked Questions

1) What cable sizes does the Thomas & Betts HSC2-20 end cap fit?
The HSC2-20 heavy-wall end cap covers 6 to 2 AWG cable. It goes on at a minimum expanded inside diameter of 0.75 inch and recovers down to 0.24 inch maximum ID, so it grips tightly over conductors in that range. Standard length is 2.5 inches.
2) What temperature do I need to hit to shrink the HSC2-20, and will a heat gun do it?
Shrink temperature is 120 C. That is above what a hot-air blower on low will reach reliably, so use a proper heat gun or torch-style shrink tool and work the heat around the cap evenly until the adhesive liner flows out at the open end. Once installed it operates from -55 C to 110 C.
3) Will a heat shrink end cap actually seal a cut cable end against water?
Yes. The HSC2-20 is lined with adhesive that melts and flows during shrinking, bonding to the jacket and sealing the end against moisture and common fluids and solvents. It is also built with extra wall thickness at the tip so the cut strands of the conductor don't punch through the seal, which is the usual failure mode with plain tubing folded over an end.
4) Is the HSC2-20 rated for 600V circuits?
It carries a 600V rating, with a nominal recovered wall of 0.09 inch, so it is suited to building wire and feeder cable ends in branch and feeder work rather than medium-voltage terminations.
5) Are these heat shrink end caps UL listed and flame rated?
The HSC2-20 is UL and CSA recognized and carries a UL 94 V-0 flammability rating, which is the self-extinguishing class inspectors look for on insulating materials in panels and enclosures.
6) Do I have to buy these in a box, or can I order a few pieces?
HSC2-20 caps are sold each, but the order multiple is 10, so quantities come in increments of ten. Inner package is 10 and the outer carton holds 100.
7) Can I use these caps to seal off an empty conduit stub or an unused cable end left in a vault?
Yes, that is a normal use. The HSC2-20 seals cable ends, pipe and conduit stubs, with the adhesive liner closing it off against moisture ingress. Just confirm the opening falls inside the 0.75 inch expanded ID so the cap slides on, and that it recovers enough to grip (0.24 inch minimum recovered ID).
8) Will these end caps hold up outdoors in a cold climate?
Operating range runs -55 C to 110 C, so winter service down well below zero is within spec, and the adhesive-lined construction plus resistance to common fluids and solvents suits direct-buried and vault work. The heavy wall (0.09 inch recovered) gives it more mechanical toughness than thin-wall tubing in those locations.
9) Is the Thomas & Betts HSC2-20 RoHS compliant?
No. The HSC2-20 is listed as not RoHS compliant, which matters if you are specifying for a project with restricted-substance requirements. It is black in color.
