ASTM B88 Copper Water and Gas Fittings are produced using high quality seamless copper tubes which are used for dependability in plumbing, supplying water, heating and gas piping systems. These ASTM B88 Copper Water And Gas Fittings are leak proof, have good corrosion resistance and can last long hence they can be applied both in residential as well as commercial applications. They conform to ASTM B88 requirements and can be used with Type K, L, and M copper pipes and they are highly efficient in terms of strength and durability under different pressure and temperatures. These fittings are ideal in the consumption of potable water, natural gas, and HVAC where the copper fittings provide safety, efficiency and homogeneity.
ASTM B88 Copper Water And Gas Fittings – Types
ASTM B88 Copper Water and Gas Fittings are of a large variety of different types to accommodate different plumbing, heating, and gas installation applications. These product ranges are Tees, Elbows (90deg/45deg), Couplings, Copper Reducers, Copper End Caps, Unions, Nipples, Sockets, and Adaptors. All fittings are specially designed to be used with ASTM B88 copper pipes in Type K, L, and M, and allow very strong, leak-free and well-resistant joints to corrosion. These copper fittings are residential and commercial in nature being suitable in water supply, HVAC, and natural gas pipelines, having high durability, and long-term reliability.

FAQ (Frequently Asked Questions)
Can ASTM B88 copper fittings be used for gas?
Copper fittings may be permitted for certain fuel-gas applications, but ASTM B88 is a water-tube specification, not a gas-fitting standard. Gas installations must use fittings and tubing approved for the specific gas service and comply with applicable fuel-gas codes and local regulations.
What are ASTM B88 copper fittings?
ASTM B88 copper fittings are fittings used to connect copper water tubing in plumbing and water distribution systems. ASTM B88 itself specifies seamless copper water tube, while the fittings used with that tubing are generally manufactured to applicable fitting standards such as ASME B16.22.
