Our pipe fitting copper products are available in many forms to suit different installation needs. We carry all major types, including:

Elbows (45°, 90°, street elbows)
Tees
Couplings / Unions
Reducers / Adapters
Flanges, caps & unions

Applications of Copper Fittings

Copper applications are widely used in both residential and commercial plumbing systems. Their versatility and strength make them ideal for:

Hot and cold water supply lines
Heating and cooling (HVAC) systems
Gas distribution lines
Refrigeration and compressed air systems

They are particularly valued in environments where a secure, leak-proof, and corrosion-resistant connection is essential.

Copper Fittings Sizes and Standards

All our fittings adhere to recognized industry standards (ASME, ASTM, MSS) to ensure compatibility and performance.

Available in:

Type K, L, and M for different wall thicknesses and pressure ratings
Sizes ranging from 1/8" to 8" nominal diameter

Always refer to standard sizing charts to ensure the proper fit for your system requirements.

Benefits of Copper Fittings

Corrosion Resistance: Withstands moisture and chemical exposure for long service life.
Heat Tolerance: Performs reliably in both hot and cold water systems.
Ease of Installation: Simple to solder, braze, or press-fit.
Hygienic and Safe: Naturally inhibits bacterial growth, making it ideal for potable water.
Recyclable Material: Environmentally friendly and sustainable.

How to Choose the Right Copper Fitting

Selecting the correct copper fitting depends on:

Application: Determine if it’s for water, gas, or HVAC use.
Pressure and Temperature: Match the fitting’s rating to system conditions.
