Valve Union Fittings

Valve Union Fittings

Mating parts join valves to a line for quick connection and removal

On-Off Valves

Start and stop flow through a line

Check Valves

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

Flow-Adjustment Valves

Flow-Adjustment Valves

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

Orifice Valves

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

Diverting Valves

Diverting Valves

Redirect flow between ports

Backflow-Prevention Valves

Backflow-Prevention Valves

Dual checks stop flow from reversing and contaminating your system

Float Valve Bodies

Float Valve Bodies

Pair with floats and rods to create float valves that meet your needs

Electrical

Conduit and Conduit Fittings

Protect wiring from impact and the environment in runs indoors, outdoors, and underground

Lubricating

Grease Fitting Adapters

Grease Fitting Adapters

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

Power Transmission

Rod Ends

Use with connecting rods to support loads and control steering, tensioning, or pivoting motion

Swivel Joints

Handle shaft misalignment where ball joint rod ends won’t fit; also known as spherical bearings

U-Joints

Transfer torque between shafts at an angle; handle more torque and misalignment than flexible shafts

Pivot Bearings

Best for applications that require small, precise oscillating motion with limited twisting
