Fluid Handling

Pipe Fittings

Form threaded, barbed, flanged, and other types of connections between lengths of pipe

Pipe Flanges

Create an access point in a line by bolting two same-size flanges together with a gasket

Hose Fittings

Create threaded, barbed, quick-disconnect, and other types of connections between lengths of hose

Manifolds

Distribute air or fluid to multiple places from a single source; also called headers

Tube Fittings

Make threaded, push to connect, barbed, and other types of connections between lengths of tube

Pressure-Relief Valves

Pressure-Relief Valves

Protect equipment by opening at a set pressure and closing when the pressure drops; for repeated use

Pressure-Regulating Valves

Pressure-Regulating Valves

Reduce inlet pressure to a lower outlet pressure to protect sensitive equipment

Vacuum-Regulating Valves

Vacuum-Regulating Valves

Control the amount of air that a vacuum pump draws from your system to maintain vacuum levels

On-Off Valves

Start and stop flow through a line

Air-Exhaust Valves

Air-Exhaust Valves

Vent or divert exhaust to speed up the operation of air cylinders, actuators, and other equipment
