Nylog

Nylog is a specialist refrigeration and HVAC sealant designed to enhance the reliability and performance of threaded and flared connections in air conditioning and refrigeration systems. Formulated from highly refined refrigeration oil, Nylog remains flexible and non-hardening, creating a leak-resistant seal without contaminating the system. It is widely used by HVAC technicians to prevent refrigerant leaks at flare fittings, gaskets, and threaded joints while maintaining system integrity under pressure and temperature changes. Compatible with a wide range of refrigerants and oils, Nylog is trusted for its ease of application, chemical compatibility, and long-term sealing performance in professional HVAC/R installations and maintenance work.
