1,809 Products

Sealing

Rod Wipers

Scrape dirt off rods to keep the inside of cylinders clean

Rod Seals

Maintain pressure inside cylinders and prevent fluid leaks

Shaft Seals

Prevent leaks in motors, pumps, and gearboxes

U-Cup Seals

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

Spring-Loaded Seals

Spring-Loaded Seals

Seal rods and pistons with a wider range of temperature and chemical resistance than U-cup seals

Piston Seals

Prevent leaks inside pistons by creating a seal against the cylinder bore

Wear Rings

Guide rods and pistons to prevent uneven wear and extend the life of seals

Wear Ring Stock

Wear Ring Stock

Cut to make wear rings that fit any rod or bore to prevent uneven wear and extend the life of seals

Buffering Seals

Buffering Seals

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

Packing Seals

Fill in gaps around pump shafts, valve stems, and agitators to prevent leaks

Packing Seal Lubricating Rings

Packing Seal Lubricating Rings

Install between layers of packing seals to distribute lubricants evenly; also known as lantern rings

Cushioning Seals

Cushioning Seals

Reduce wear and noise in air-powered cylinders by blocking the piston from hitting the cylinder body

Head Seals

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

Building and Machinery Hardware

Bellows

Prevent dust and debris from damaging moving parts

Way Wipers

Sweep debris away from machining tables, rails, and ball screws

Power Transmission

Cylinder Rod Glands

Cylinder Rod Glands

Replace the rod gland on hydraulic cylinders

Hydraulic Cylinder Seals

Hydraulic Cylinder Seals

Replace seals on the piston or rod end of hydraulic cylinders

Springs

Apply and absorb force with compression, die, extension, torsion, and disc springs

Material Handling

Screw Conveyors

Screw Conveyors

Push material through fixed troughs
