Viper (Refrigeration Tech) RT201BP Nylog Blue Sealant 2-Pack

The Viper (Refrigeration Tech) RT201BP Nylog Blue Sealant 2-Pack is a gasket and thread sealant formulated to reduce leakage at threaded fittings, flare connections, O-rings and gasket surfaces. Its synthetic refrigeration-grade composition remains pliable after application, creating a sealing layer that fill microscopic surface irregularities while allowing connected parts to tighten smoothly. A thin coating is applied to the designated sealing surfaces before assembly, allowing HVAC systems to maintain tightly sealed refrigerant connections without introducing contaminants into the circuit. It reduces the possibility of refrigerant loss, maintains sealing integrity at mating surfaces and allow connected fittings to separate more easily during future maintenance.
