EPDM cold shrink end cap

Product Description

EPDM Cold Shrink End Cap is a pre-expanded, factory-assembled rubber cap designed to provide fast, reliable sealing and insulation for cable ends. Made from high-performance EPDM rubber, it shrinks automatically after removal of the inner support core, forming a tight, moisture-proof seal without the need for heat or special tools. It is ideal for indoor and outdoor applications in power distribution and telecommunications systems.
