Raw Materials

Rubber

Compresses and bounces back to shape; often used for sealing, cushioning, and shock absorbing

Foam

Pockets of air make it lighter in weight than rubber; good for packing, insulating, and sealing

Plastic

A lightweight alternative to metal and glass

Sealing

Edge Seals

Block dust, water, and wind from entering the gaps around doors and windows

O-Rings

Fit snugly into a groove between parts to create a leak-resistant seal

O-Ring Cord Stock

O-Ring Cord Stock

Cut to length to create customized seals

Gasket Material

Gasket Material

Cut custom shapes and sizes to fill gaps between flat surfaces

Pipe Gaskets

Form tight seals when connecting flanged pipe fittings

Sealants

Fill and seal gaps in metal, plastic, wood, and other materials

Fluid Handling

Tubing

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

Building and Machinery Hardware

Bumpers

Absorb impact to protect equipment and surfaces from dents and scuffs
