Refrigeration Pipe Fittings & Connectors for AC & HVAC

Copper and brass fittings for air conditioning and refrigeration pipework — elbows, tees, reducers, couplers, flare fittings, service valves, and tank adapters. Full size range from 3/8" to 1 5/8" OD for all standard refrigerant circuit connections. Same-day dispatch from UK stock.

Copper Fittings

Refrigeration-grade copper fittings for solder-end connections on refrigerant circuits. Copper fittings include 90° short radius elbows, 45° elbows, street elbows, socket couplers, and reducers in sizes from 3/8" to 1 5/8" OD. All fittings are manufactured to refrigeration grade — dehydrated and suitable for use with all common HFC and HFO refrigerants. Braze with silver brazing rods at the correct temperature to avoid overheating the fitting.

Brass Fittings & Flare Connectors

Brass fittings for flare connections, compression joints, and service access points. Flare fittings in 1/4", 3/8", 1/2", and 5/8" SAE for field connections on refrigerant lines. Schrader valve cores and caps for service port maintenance. Refrigerant tank adapters including 3/4" NPS and European 21.8-14 fittings for cylinder connections.

Service Valves & Adapters

Ball valves, service valves, and Schrader access fittings for refrigerant circuit isolation and service access. Browse all valves including ball valves and check valves. Mastercool refrigerant tank adapters for connecting manifold hoses to refrigerant cylinders in standard and European configurations.

Selecting the Right Fitting

Match fitting material and type to the application — copper solder fittings for permanent brazed joints, brass flare fittings for field-serviceable connections, and stainless or brass for outdoor and high-corrosion environments. Always use refrigeration-grade fittings on refrigerant circuits — plumbing-grade fittings are not rated for refrigerant pressures or temperatures.
