Brass and bronze have good corrosion resistance. They are often used in drinking water and plumbing applications. Brass and bronze are compatible and can be used interchangeably.

Aluminum Pipe and Pipe Fittings

testString

Aluminum has good corrosion resistance and is lightweight.

Plastic Pipe and Pipe Fittings

testString

Plastic pipe and pipe fittings are lighter in weight than metal pipe and pipe fittings. They are typically for low- to medium-pressure applications up to 1,000 psi.

Hose Fittings

Connect these fittings to lengths of hose. Hose fittings are typically used in high-flow, suction, and hydraulic applications.

Tube Fittings for Metal Tubing

Fittings are designed for medium- to high-pressure applications. They connect to tubing or pipe.
