3M 7000031605 – Frequently Asked Questions

1) What voltage is the 3M 8425-8 cold shrink tube rated for?
It is a low voltage product rated to 1 kV (1000 volts). Use it for primary insulation on solid dielectric insulated wire and for splices at or below that level. It is not a medium voltage splice or termination product, and it is specified for non-shielded cable, so do not put it on shielded MV cable.
2) Do I need a torch or heat gun to install the 8425-8?
No heat at all. Cold shrink means the EPDM tube is factory-expanded on a removable core; you slide it into position and pull the core out, and the rubber recovers onto the cable by itself. No tools, no flame, which is why crews use it in energized-adjacent or confined spaces where an open flame is a problem.
3) Is the 3M 8425-8 cold shrink insulator UL listed or halogen free?
Two points for a spec review: the 8425-8 does not carry a UL approval, and it is not halogen free. It is RoHS 2011/65/EU compliant without exemption and made in the United States. If your job spec calls for a UL listed or halogen-free insulator, this is not the part.
4) Can the 3M 8425-8 cold shrink insulator be used outdoors or in a cold climate?
Its service range is -40 to 90 degC (-40 to 194 degF), so winter exposure and hot conduit runs are both inside spec. The EPDM rubber contains no chlorides or sulfur, which is what keeps it from attacking the conductor over time.
5) What jobs is the 8425-8 cold shrink tube actually used for besides splices?
Three common ones beyond insulating a splice: sealing terminal lug barrels, sealing conduit couplings, and sealing conduit-to-cable breakouts. The catalog application is insulation, mechanical protection and repair, so it also works as a jacket repair over damaged cable within its diameter range.
6) How thick is the wall on the 8425-8 once it recovers, and does it seal without mastic?
Wall thickness after shrinking is 3.8 mm. There is no inner glue or adhesive lining; the seal comes from the EPDM's own elastic pressure against the cable, so surfaces need to be clean and free of sharp edges for a tight grip.
