Copper Pipe Fittings
Metracore Alloys supplies copper pipe fittings to fabricators, HVAC contractors and plant buyers across India and overseas markets. Stock covers elbows, tees, reducers, couplings, caps, unions and adapters in grades C12200, C12000, and C10200, dimensioned to ASME B16.22 with socket bores sized to accept copper tube to ASTM B88 and ASTM B280. Copper conducts heat at 339 to 391 W/m·K at 20°C, depending on grade. It resists corrosion in potable water and refrigerant service, and it joins by soldering, brazing or compression without specialised plant equipment. Those properties keep copper fittings in HVAC, refrigeration, plumbing, water supply and heat-transfer piping decades after cheaper polymer alternatives arrived.

Why Choose Copper Pipe Fittings?
Eight practical benefits keep copper ahead in building services and industrial pipework despite steady competition from polymer piping systems.
- Heat transfer is enhanced by copper’s conductivity of 339 W/m·K and moves energy quickly through heating and cooling circuits.
- Corrosion resistance stems from a stable oxide film that develops in most waters and shields the metal beneath.
- Soldered sockets seal around the entire circumference, giving leak-proof connections at every joint.
- Service life runs for decades in water distribution duty.
- Fabrication stays simple: the metal bends, flares, and solders with hand tools.
- Recyclability is necessary, as scrap fittings melt back into production without losing material properties.
- Upkeep stays low because copper resists internal corrosion and slows biofilm formation, though hard water will deposit scale on copper as on any pipe material.
- Hot and cold water systems both sit inside its service envelope.
Sizes, Dimensions & Standards
Dimensional interchangeability defines this product group, since any compliant tube must enter any compliant socket regardless of which mill made either part.
Wrought solder-joint pressure fittings follow ASME B16.22, which fixes socket diameters, wall thicknesses, and tolerances across the 1/4 to 8-inch range. Rated working pressures follow ASME B31.9 and CDA tables. Cast solder-joint fittings sit under ASME B16.18 instead. Tube compatibility spans ASTM B88 Types K, L, and M, plus ASTM B75 seamless tube and ASTM B280 refrigeration tube. Pressure class depends on size, wall, and the joining alloy chosen; brazed joints carry higher ratings than soft-soldered ones.
Manufacturing Process of Copper Pipe Fittings
Thermal conductivity, corrosion resistance and joint simplicity decide where copper fittings go:
Copper doesn’t belong on ammonia refrigerant lines. Ammonia attacks copper directly, so carbon steel is the correct material there.

FAQs
What Are The Common Grades Used For Copper Pipe Fittings?
C12200 covers most fittings, backed by C12000 where higher conductivity is wanted and C10200 for oxygen-free service. C122 and DHP copper are named the same material as C12200.
Where Are Copper Pipe Fittings Used?
HVAC circuits, refrigeration lines, plumbing networks, potable water supply, heat exchangers and industrial process piping all run copper fittings.
What Types Of Copper Pipe Fittings Are Available?
Seven core shapes plus three joint variants: elbows, tees, reducers, couplings, caps, unions, and adapters, supplied as solder, brazing or compression fittings.
What Standards Are Used For Copper Pipe Fittings?
ASME B16.22 governs wrought solder-joint fittings, and ASME B16.26 covers flared types. Tube specifications ASTM B75, B88, B280, and B68 apply alongside EN 1254 on European orders.
How Do I Select The Right Copper Pipe Fittings?
Match six variables: grade, size, wall thickness, connection method, operating pressure and fluid compatibility. Confirm the governing standard last, since it follows from the fitting type already chosen.
