How can we improve?

37,722 Products

Fluid Handling

Hose Fittings

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

Hose

Flexible and stronger than tubing; often used to convey liquids and gases under pressure

Tube Fittings

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

13,305 products

Pipe and Fittings

Pipe and Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases

17,169 products

Pipe Expansion Joints

Pipe Expansion Joints

Reduce stress, vibration, and noise in piping systems by absorbing movement

Pipe Traps

Create a seal that prevents the backflow of gas

Pipe Stub Ends

Connect a pipe flange to a pipe without needing to weld it in place

Air Chucks

Connect air hose to Schrader valves, which are common on tires and hydraulic systems

Manifolds

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

Junction Blocks

Junction Blocks

Organize and separate multiple lines in a pipe system; air and fluid flow through the threaded holes

Hose Crimpers

Crimp ferrules onto hose to secure fittings

Manual On/Off Valves

Manual On/Off Valves

Start and stop flow through a line

Solenoid On/Off Valves

Solenoid On/Off Valves

A solenoid withstands rapid cycling for applications with frequent opening and closing

Motor-Actuated On/Off Valves

Motor-Actuated On/Off Valves

An electric motor handles higher flow rates and pressures than solenoid valves

Air-Actuated On/Off Valves

Air-Actuated On/Off Valves

Operate on compressed air to start and stop flow faster than motor-driven valves

Measuring and Inspecting

Hose Coupling Size-Identification Kits

Hose Coupling Size-Identification Kits

Match your hose coupling to one of the plugs to determine its size without measuring

Fastening and Joining

Brazing Rings

Snap into unthreaded pipe fittings for an extra-strong, leak-resistant connection

Power Transmission

Compressed Air Filter/Regulator/Lubricator Manifolds

Compressed Air Filter/Regulator/Lubricator Manifolds

Distribute compressed air to multiple locations from a single source
