3M Cold Shrink Insulators offer a safe, easy to install method of insulating, sealing and protecting connectors, cable, hoses, fittings and conduit. The EPDM rubber insulators are supplied pre-stretched on a removable core. Removal of the core (unwinding) after positioning the splice allows the product to shrink into position forming a moisture tight seal.
The live memory action of the specially formulated material provides a permanent, durable environmental seal and insulation, with an operating temperature range of -40⁰C to 90⁰C.
