10,878 Products

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

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

Buffering Seals

Buffering Seals

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

Wear Rings

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

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

Packing Seals

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

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

O-Ring Cord Stock

O-Ring Cord Stock

Cut to length to create customized seals

Backup Rings

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

Thread Sealants

Thread Sealants

Create a seal between threaded connections to prevent loosening from vibration

Sealants

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

Fluid Handling

Gauge Guards

Shield gauges from corrosive liquids and gases; also called diaphragm seals

Tube and Tube Fittings

Tube and Tube Fittings

Typically more flexible than pipe for carrying liquids and gases in short runs around equipment
