How can we improve?

6,303 Products

Raw Materials

Plastic

A lightweight alternative to metal and glass

Rubber

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

Garolite

A strong, machinable alternative to metal and plastic widely used in circuit boards and gears

Foam

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

Carbon Fiber

The strongest composite we offer; comparable in strength to 6061 aluminum but lighter in weight

Fiberglass

A lightweight alternative to metal and wood widely used in electrical and structural applications

Lead

A dense insulator often used to shield against radiation and absorb sound and vibration

Hard Fiber

Chemically treated to be hard and dense, this is the easiest composite to machine in our offering

Kevlar

Super tough for protection against prolonged wear and abrasion

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Sealing

Backer Rods

Insert into gaps before caulking to reduce how much sealant you need and improve adhesion

Fluid Handling

Tube and Tube Fittings

Tube and Tube Fittings

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

Slip-On Framing and Fittings

Slip-On Framing and Fittings

Insert rails into fittings and tighten screws to make guards, railings, and racks

Fastening and Joining

Shims

Level, align, and adjust spacing on fasteners, shafts, and machine components

Measuring and Inspecting

Metal Detector Calibration Kits

Metal Detector Calibration Kits

Test the sensitivity of food-processing metal detectors
