Fluid Handling

Pipe Fittings

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

Pipe Nipples and Pipe

Pipe Nipples and Pipe

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

Pipe Flanges

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

Pipe Plugs

Insert into the ends of pipe to keep out dirt and debris

Expansion Joints

Expansion Joints

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

Pipe Caps

Cover the ends of pipe to keep out dirt and debris

Pipe Fitting Clamps

Pipe Fitting Clamps

Connect easy-access and grooved-end pipe fittings to pipe

Rotary Unions

Transfer air, water, oil, and steam from supply lines to continuously revolving drums and rollers

Pipe Repair Clamps

Pipe Repair Clamps

Fix small holes and cracks in pipe without taking your system apart

Hose and Hose Fittings

Hose and Hose Fittings

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

Tube Repair Clamps

Tube Repair Clamps

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

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment

Orifice Valves

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

Fastening and Joining

Brazing Rings

Snap into metal pipe and tubing to form leak-resistant joints more quickly than with hand-fed alloys

Lubricating

Grease Fitting Adapters

Grease Fitting Adapters

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

Grease Gun Tips

Grease Gun Tips

Attach to grease gun nozzles and direct a stream of lubricant into grease fittings on machinery
