FlareSeal 40 Pack Starter Kit – Leak-Free SAE Flare Fittings for Refrigeration & HVAC

Clip-on reliability for SAE flare fittings

FlareSeal is an engineered copper gasket featuring a multi-ring flare surface and a thread lock coating. This combination creates an easy clip-on solution that accommodates minor surface scratches and slight misalignments between male and female flare fittings. Designed for a wide range of SAE 45-degree flare sizes, FlareSeal aims to help installers and technicians achieve tidy, reliable connections in refrigeration, HVAC and ductless systems without the guesswork of traditional seals.

The 40 Pack Starter Kit is part of a family that also includes 10 packs, larger quantity options, and a locking container Variety Pack with 60 seals for your toolbox. The Schrader-Seal variant targets leaks at Schrader valve points, while mini-split specific packs simplify leak-free ductless installations. FlareSeal can even be used to address leaks on existing flare connections, making it a versatile addition to service carts and workshop shelves.
