255 Products

Sealing

Rod Seals

Maintain pressure inside cylinders and prevent fluid leaks

Piston Seals

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

Rod Wipers

Scrape dirt off rods to keep the inside of cylinders clean

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

Packing Seals

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

Shaft Seals

Prevent leaks in motors, pumps, and gearboxes

Wear Rings

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

Cord Stock

Cut to length to create customized seals
