Cooper Fittings

Copper pipe fittings are most often used for hot and cold water supply lines in refrigerants and HVAC systems. Because copper has so much tensile strength and allows liquid to flow freely through pipes, copper is used for other applications as well.

The pipe fittings are manufactured by reliable manufacturers using quality copper, whether soft or rigid copper, are of a variety of types, such as couplings, copper caps, copper reducers, copper adaptors, copper elbows and copper return bends. Their precise design, resistant to rust, reliability, and long service life make these copper piping devices popular with customers around the world.
