Tube Fittings for Metal Tubing

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

Hose Fittings

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

Plastic Pipe and Pipe Fittings for Water

testString

Fittings have a socket-connect end that welds to pipe with cement, or a theaded end that threads onto pipe with a thread sealant. These types of connections are stronger than barbed connections and can handle pressures up to 1,000 psi.
