SAE 45 Degree Brass Flare Fittings for HVAC, Refrigeration & Gas Systems Male Female Union Adapter

Product Description

Our Brass Flare Fittings are manufactured to deliver reliable, leak-free connections for gas, refrigeration, HVAC, and fuel line applications. Constructed from high-quality forged brass, these fittings offer excellent corrosion resistance, high-temperature durability, and superior mechanical strength.

Designed for use with copper, brass, aluminum, and steel tubing, flare fittings provide a secure mechanical seal without the need for soldering. When properly flared using standard tools, the connection ensures long-term stability even under vibration, high pressure, or temperature fluctuation.

This series covers a complete range of flare adapters, unions, elbows, tees, nuts, caps, branch tees, and custom flare accessories—compatible with LP and natural gas, fuel systems, plumbing, refrigeration, and BBQ equipment.
