Sealing

Shaft Seals

Prevent leaks in motors, pumps, and gearboxes

Piston Seals

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

Spring-Loaded Seals

Spring-Loaded Seals

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

Rod Seals

Maintain pressure inside cylinders and prevent fluid leaks

Wear Rings

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

Rod Wipers

Scrape dirt off rods to keep the inside of cylinders clean

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

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

O-Rings

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

Backup Rings

Extend the life of O-rings and improve their performance under high pressure

Tube Fitting Gaskets

Tube Fitting Gaskets
