Nylog Blue

Nylog Blue is a high-performance viscoelastic fluid derived from synthetic refrigeration oil. It forms a tenacious, non‑hardening seal across diverse substrates and stays active over time, never drying out or losing its sealing integrity. Because it’s fully miscible and compatible with a wide range of refrigerants and compressor oils, it won’t cause blockages or system damage. Used by OEMs and HVAC professionals worldwide as both a sealant and a lubricant, Nylog Blue makes your joints tighter and your system more reliable.
