Gamma Cold Shrink is a silicone tubing/sleeving that installs in seconds without the need for heat or adhesive. It is thicker and more durable than heat shrink or tapes and, unlike tapes, because it is a single piece/unit it is near impossible for dust or water to work their way inside. Gamma Cold Shrink is the optimal weatherproofing solution that also helps seal your connection and protect it against vibration. Gamma Electronics designs and manufactures silicone cold shrink for numerous popular connector sizes including 7/16 DIN, 4.3-10, and Type N and for cables ranging in size from LMR 195’s up to Standard ½ inch coax.
