How can we improve?

2,102 Products

Sealing

U-Cup Seals

With a lip on both the inside and outside edges, they can be used for sealing rods and pistons

Rod Wipers

Scrape dirt off rods to keep the inside of cylinders clean

Rod Seals

Maintain pressure inside cylinders and prevent fluid leaks

Head Seals

Maintain a seal even under fluctuating pressure; more reliable than an O-ring with a backup ring

Buffering Seals

Buffering Seals

Protect hydraulic cylinders from pressure spikes and shock in high-pressure applications

Sealants

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

Sealant Primers

Sealant Primers

Apply to surfaces before sealant to speed up drying times and improve adhesion

O-Rings

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

Gasket Makers

Seal irregular shapes and tiny crevices by applying a bead that hardens into a gasket

Raw Materials

Rubber

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

Power Transmission

Hydraulic Cylinder Seals

Hydraulic Cylinder Seals

Replace seals on the piston or rod end of hydraulic cylinders

Cylinder Rod Glands

Cylinder Rod Glands

Replace the rod gland on hydraulic cylinders

Fastening and Joining

Adhesives

Adhesive Primers

Adhesive Primers

Prepare surfaces before adding adhesives to improve bonding strength

Cushioning Washers

Cushioning Washers

Cushion joints to dampen vibration and protect them from wear

Tape

Bind, seal, and mark surfaces

Fluid Handling

Pressure Test Fittings

Pressure Test Fittings

Create a temporary connection point for gauges and other testing equipment
