These U-cup seals create less friction than O-ring-loaded U-cups, so they wear more slowly. Also known as lip seals, U-cups have a sealing lip on both the inside and outside edges, so they can be used for rod and piston sealing.
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.
For use in air-powered cylinders, these seals prevent the piston from slamming against the cylinder body to minimize wear and noise.
PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.
A square O-ring prevents these piston seals from rocking in the groove.

These silicone O-rings withstand temperatures up to 400° F or 450° F.
Able to withstand temperatures up to 400° F, these O-rings are softer than standard silicone O-rings for a better seal in low-pressure applications.
When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements. These O-rings withstand temperatures up to 450° F.
These square-profile O-rings have flat edges on all four sides, so they cover more surface than round-profile O-rings for a better seal in static applications, such as hose, pipe, and faucet connections.

PTFE provides a slippery surface that keeps threads from binding. These sealants never fully harden, remaining pliable enough to self-heal and stop leaks before they start.
These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.
Formulated to flow into small spaces, use these sealants between fine threads.
Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse threads.
Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.
Remaining pliable over time, these high-temperature sealants protect against leaks caused by vibration and pressure—they naturally fill voids before leaks can develop.
Completely free of oil and chemically inert, these sealants are safe to use with wet and dry oxygen systems.
Formulated for high lubricity, these sealants allow easy assembly of finely threaded hydraulic and compressed air system components. They're also free of fillers that could contaminate system media.
Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.
This tape has a higher density than standard tape for a better seal between threads.
Use color to identify water, gas, and chemical connections.
This tape contains nickel to prevent seizing and galling associated with stainless steel threaded connections. It’s also good for use with other metals.
With 10% copper flake content, this tape matches the color of copper, brass, and bronze threads for a seamless finish.
Designed to withstand extreme environments, these fluoroelastomer sealants have excellent resistance to harsh chemicals. They’re non-sagging, so they won't drip from vertical and overhead surfaces.
Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
Wrap this tape tightly around pipe and other surfaces to seal cracks and joints without having to shut down your system.
