HEAT SHRINK BUTT CONNECTORS Adhesive lined butt connector's, used to join two wires together in line.Simply enter a wire into each end so they cross in the middle, crimp the central metal section to secure and heat with a hot air gun to shrink tight onto the wires.When heated the connector shrinks and the adhesive lining melts and flows around the material being covered giving a permanent weatherproof bond.Three sizes available; Red ~ 22 - 16awg / 0.5mm² - 1.5mm² Blue ~ 16 - 14awg / 1.5mm² - 2.5mm²Yellow ~ 12 - 10awg / 4mm² - 6mm²High quality, cost effective, commercial grade for electrical, electronic, automotive and general industrial markets.High strength and resilience.Minimum Shrinkage Temperature ~ +70 Degrees CFull Recovery Temperature ~ +100 DegreesOperating Temperature ~ -55C to +Tensile Strength ~ 14MpaDielectric Strength ~ 20kv/mmRoHS Compliant
