28 Products

Fluid Handling

Tubing

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

Tube Supports

Slip into plastic and rubber tubing to prevent them from collapsing

Tube Fittings

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

Pipe

Join with fittings and additional lengths of pipe

Pipe Bushings

Connect two pipes of different diameters

Hose and Hose Fittings

Hose and Hose Fittings

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

Raw Materials

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments—all with material certificates for traceability

Glass

Clear and highly heat and chemical resistant; often used in sights, lighting, and lab equipment

Building and Machinery Hardware

Strut Channel Routing Clamps

Strut Channel Routing Clamps

Route pipe, tubing, and conduit across strut channel
