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 Plugs

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

Pipe Caps

Cover the ends of pipe to keep out dirt and debris

Pipe Flanges

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

Pipe Locknuts

Thread onto the male end of a pipe fitting so it won't loosen from vibration

Rotary Unions

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

Tube Fittings

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

Tube End Plugs

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

Tube End Caps

Cover the ends of tube to keep out dirt and debris

Hose Fittings

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

Hose Fitting Nuts

Hose Fitting Nuts

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

Hose Nozzle Swivels

Hose Nozzle Swivels

Rotate to prevent hose from kinking, twisting, and wearing

Manifolds

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

Air Chucks

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

Junction Blocks

Junction Blocks

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