Thomas & Betts HS16-12-4 – Frequently Asked Questions

1) Will Thomas & Betts HS16-12-4 heat shrink tubing fit over a 14-10 AWG splice?
Yes. The HS16-12-4 is sized for 14 to 10 AWG cable. It goes on at a minimum expanded inside diameter of 0.35 inch, so it slides over the connector and cable, and recovers down to a maximum 0.12 inch ID at a 3:1 shrink ratio. It is rated to cover an aluminum/copper splice up to 1 inch long, so check your connector body length before ordering.
2) Is this heat shrink tubing suitable for direct burial or a submersible pump splice?
Yes, that is what the heavy-wall, internally sealed construction is for. The HS16-12-4 carries factory-applied sealant that flows when heated to seal out moisture, and it is used on underground residential distribution, submersible cable, and direct burial splices. The recovered wall is 0.07 inch nominal, thicker than the typical cable jacket it covers.
3) Can HS16-12-4 tubing be used on a 480V or 600V circuit?
The tubing is rated 600V, so it covers 480V and 600V class secondary distribution work as well as standard 120/240V branch circuits. It is not a medium-voltage product.
4) What length does each piece of HS16-12-4 tubing come in, and can I cut it down?
Each stick is 48 inches long and sold individually, so one piece covers several splices if you cut it to length. Cut pieces long enough to overlap the connector and cable jacket on both ends so the internal sealant has jacket to bond to.
5) What temperature do I need to hit to shrink this tubing properly?
Shrink temperature is 120 degrees C. Use a heat gun or torch with a soft flame and work from the center outward so air and excess sealant push out the ends. Once recovered, the tubing operates from -55 C to 110 C.
6) Will this tubing work over aluminum cable, not just copper?
Yes. The heavy-wall cross-linked polyolefin seals over lead, steel, aluminum, copper, and plastic insulating materials, which is why it is specified for mixed aluminum/copper underground splices.
7) Do I have to buy HS16-12-4 in multiples, or can I order a single piece?
It is sold each, but the order multiple is 5, with 5 pieces to an outer package. So quantities come in fives.
8) Is this tubing RoHS compliant for a government or institutional spec?
Yes, the HS Series black heavy-wall tubing is RoHS compliant, and the description states UL and CSA certification. That combination is what most public-agency and healthcare electrical specs ask for on splice insulation.
9) What color is the Thomas & Betts HS Series heavy-wall tubing, and does it matter outdoors?
Black. For buried, submersible, and exposed outdoor splices that is the color you want, since the carbon-loaded black compound is the UV-stable option in the HS Series.
10) How much does Thomas & Betts HS16-12-4 tubing weigh for a bulk order?
24 lbs per 100 pieces, so roughly a quarter pound per 48 inch stick. Useful if you are staging a van or pricing freight on a large underground job.
