COPPER FITTINGS - T2 Copper, Full Range for Refrigeration Piping
Kilterra T2 copper fittings are manufactured with precision, covering elbows, tees and couplings for reliable brazed connections.
Strict dimensional and material control ensure consistent quality; bulk supply with fast delivery is available.
Our copper fittings range covers elbows, tees and reducers in various sizes, suitable for brazed connections.
Six core advantages that keep your refrigeration system protected around the clock
Made of T2 copper (≥99.9% Cu) with high conductivity, good ductility and corrosion resistance - the first choice for piping.
Elbows, tees, straight/reducing couplings, U-bends, sight glasses and drain valves across the full line.
T2 copper brazes superbly for strong, sealed joints that resist cold joints and leaks.
Precision machined and pressure tested to withstand high pressure and resist refrigerant/oil corrosion.
Precision molds and CNC machining give accurate port dimensions that mate tightly with copper tube.
Special sizes and shapes can be customized for non-standard systems.

Kilterra delivers professional refrigeration component solutions with OEM/ODM support.
When specifying copper fittings for refrigeration piping, wall thickness and temper matter as much as the nominal diameter. Kilterra's T2 copper elbows, tees, reducers and U-bends are supplied in soft, half-hard and hard temper, with smooth bore and uniform wall thickness to prevent turbulence and weak braze joints. Match fitting size to the actual tube OD rather than nominal pipe size, and confirm compatibility with R410A, R32 and R134a systems before ordering. Every batch ships with dimensional and material reports, and our export experience covers OEM and aftermarket buyers across Europe, the Middle East and Southeast Asia.
