Heatshrink Ring Terminals - Waterproof Crimp Rings, Red, Blue & Yellow, M4 to M12

Heatshrink ring terminals give a secure, waterproof termination onto a stud or bolt. Crimp as normal, then heat the sleeve: the 3:1 adhesive lined polyolefin insulation shrinks and seals around the cable, keeping out moisture and resisting vibration.
