Sealing

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

Rod Wipers

Scrape dirt off rods to keep the inside of cylinders clean

Rod Seals

Maintain pressure inside cylinders and prevent fluid leaks

Spring-Loaded Seals

Spring-Loaded Seals

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

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

Buffering Seals

Buffering Seals

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

Head Seals

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

Cushioning Seals

Cushioning Seals

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

Electrical

Potentiometer Panel Seals

Potentiometer Panel Seals

Keep moisture and dust out of potentiometers

Material Handling

Screw Conveyors

Screw Conveyors

Push material through fixed troughs

Power Transmission

Rod End Seals

Keep dirt out and lubrication in to extend the life of rod ends

Garter Springs

Exert radial force from all directions to maintain pressure on shafts or in seals
