ASTM B88 Copper Water And Gas Fittings

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 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 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, Reducers, 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 fittings are residential and commercial in nature being suitable in water supply, HVAC, and natural gas pipelines, having high durability, and long-term reliability.
