About Flare Fittings

Flare fittings are a trusted connection method widely used across plumbing, gas, HVAC, refrigeration, automotive, and industrial systems where a dependable mechanical connection is required. At PlumbingSell, we supply high-quality brass flare fittings designed specifically for use with soft (annealed) copper tubing, including Type K, L, and refrigeration/ACR copper. For joining two properly flared tube ends, flare unions are a practical starting point.

Why Choose Brass Flare Fittings?

Our brass flare fittings provide long-term reliability due to their corrosion resistance, temperature tolerance, and ability to withstand demanding operating conditions. They are a preferred alternative to standard brass pipe fittings when higher mechanical sealing strength or precise pressure handling is required. Where a flared tube must connect to another approved thread type, check flare adapters.

Benefits Include:

• Reusable Design — can be disconnected and reassembled without damaging tubing.
• No Soldering or Heat Required — suitable for fire-restricted job sites.
• Leak-Free Sealing — ideal for gas, fuel, hydraulic, and refrigerant connections.
• Superior Vibration Resistance — prevents loosening or failure over time.
• Wide Application Compatibility — plumbing, HVAC, gas, and industrial systems.

Whether you are working on propane appliances, HVAC service, or oil burner lines, flared fittings provide a secure and professional-grade solution. Small-diameter appliance lines often use 1/4" flare fittings, but the flare angle and thread must match.

Whether you’re servicing HVAC refrigeration lines, installing propane appliances, running heating oil connections, or completing a high-pressure plumbing system, flare fittings from PlumbingSell provide the durability and performance demanded by professionals. For a larger tube connection, compare 3/8" flare fittings by outside diameter and thread specification.
