Dynamic Seals

U-Cup Seals

U-Cup Seals

These U-cup seals create less friction than O-ring-loaded U-cups, so they wear more slowly. They're also known as lip seals.

O-Ring-Loaded U-Cup Seals

O-Ring-Loaded U-Cup Seals

Also known as loaded-lip seals and PolyPaks, an O-ring secures these U-cups to the rod or piston, for better sealing performance at lower pressures than unsupported U-cup seals.

Spring-Loaded Seals

Spring-Loaded Seals

In addition to providing excellent sealing performance at low pressure, these seals withstand a wider range of temperatures and chemicals than U-cup seals. They’re also known as spring-energized seals.

Piston Seals

Piston Seals

Making a seal between their outside edge and the cylinder bore, these seals prevent internal leaks.

Rod Seals

Rod Seals

Maintain the pressure inside cylinders and prevent fluid from leaking out.

Rod Wipers

Rod Wipers

Scrape dirt, dust, and moisture from the rod, preventing contamination inside your cylinder.

Wear Rings

Wear Rings

Used to guide the rod and piston, wear rings prevent uneven wear and optimize seal performance.

Rotary Shaft Seals

Rotary Shaft Seals

Designed for a leak-resistant seal on rotating shafts in motors, pumps, and gearboxes.

Packing Seals

Packing Seals

Packing seals are extremely flexible and conformable. They prevent leaks by filling the gaps around pump shafts, valve stems, and agitators.

Other Air Seals

Compressed Air Filter Seals

Replace failing or lost O-rings in modular compressed air filters.

Linear Motion Air Cylinders

Ball Joint Rod End Seals

Ball Joint Rod End Seals

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

Seal Kits for Hydraulic Cylinders

Control leaks and protect equipment from wear by replacing seals in your hydraulic cylinder.

Vacuum Heat Sealers

Create an airtight seal around items. These sealers remove air and seal the bag at the same time.
