Fluid Handling

Pipe and Pipe Fittings

Pipe and Pipe Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases through your facility

Hose Fitting Nuts

Hose Fitting Nuts

Connect fittings and compressed-gas nipples to pressure regulators and torches

Hose Fittings

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

Hose End Caps

Cover the ends of hose to keep out dirt and debris

Tube Fitting Nuts

Tube Fitting Nuts

Tighten to create a strong seal between tube and tube fittings

Tube Fittings

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

Orifice Valves

Restrict the flow of liquids and gases to precisely control rate and pressure

On-Off Valves

Start and stop flow through a line
