Product Identity

The 3M 8430-9 is a medium-wall cold shrink tube made from EPDM rubber. It arrives pre-expanded on a removable core and contracts without heat when the core is pulled. The tube is designed for electrical insulation and environmental sealing on large-diameter cables in utility, industrial and commercial installations.

Build Integration

The tube fits wire sizes from 1250 MCM to 2000 MCM and shrinks from a 3.69 in inner diameter down to 1.68 in. A 0.06 in wall thickness after shrinking provides mechanical protection while the 9 in length covers standard splice or termination zones. UV-resistant rubber allows outdoor exposure and the material operates from -66 to 500 degrees F without flame-retardant additives or adhesive lining.

Target User

This product suits electricians and maintenance crews who need quick, heat-free sealing on high-voltage cables up to 1,000 V dielectric strength. It is not intended for installers who require flame-retardant tubing, adhesive-lined seals or shrink ratios verified to a specific standard. Buyers working with smaller conductor sizes should select a tube with a matching pre-shrink diameter.
