12,965 products

Hose Fittings

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

2,496 products

Hose

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

56 products

Manifolds

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

619 products

Junction Blocks

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

88 products

Pipe and Fittings

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

348 products

Pipe Expansion Joints

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

47 products

Tube Repair Clamps

Mend small holes, cracks, and full-circle breaks in tubing without dismantling your system

16 products

Manual On-Off Valves

Start and stop flow through a line

583 products

Permit flow in only one direction by closing when flow stops or reverses

162 products

Flow-Adjustment Valves

Gradually open and close to control the volume of air and liquids through a line

47 products

Diverting Valves

Redirect flow between ports

34 products

Orifice Valves

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

216 products

Solenoid On-Off Valves

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

8 products

Air-Actuated On-Off Valves

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

5 products

Mufflers

Reduce noise and filter exhaust fumes

25 products

Pressure-Relief Valves

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

8 products

Lubricating

Grease Fitting Adapters

Mate grease fittings when the sizes and thread types don't match

14 products

Facility and Grounds Maintenance

Air Admittance Valves

Allow air into drain, waste, and vent systems so you don't have to vent plumbing to the outdoors

2 products
