About Cylinder Seals
Rod wipers scrape dirt, dust, and moisture from the rod, preventing contamination inside your cylinder.
Rod seals maintain the pressure inside cylinders and prevent fluid from leaking out.
Wear rings guide the rod and piston to prevent uneven wear and optimize seal performance.
Head seals are a more reliable alternative to the standard O-ring/backup ring combination—they resist twisting and remain stable even in applications with fluctuating pressure.
Buffering seals protect hydraulic cylinders from pressure spikes and shock in high-pressure hydraulic applications.
Cushioning seals minimize wear and noise in air-powered cylinders by preventing the piston from slamming against the cylinder body.
Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks.

Made-to-Order Chemical-Resistant Fluoroelastomer O-Rings
When you need a fluoroelastomer O-ring that’s not an industry standard size, we can make one to fit your requirements. Fluoroelastomer resists a wide range of chemicals, including benzene, butyl alcohol, and ethylene glycol. These O-rings have a round profile and are suitable for both static and dynamic sealing applications.

O-Ring Bonding Kits
These kits include everything you need to make your own O-rings, including cord stock, a splicing jig, adhesive, and a razor blade.
Fluoroelastomer cord stock resists boric acid, fuels, and transmission fluid.
Relacement jigs splice cord stock from 0.103” to 0.375” Wd.
Rod Wipers
Side 1
Side 2
Also known as U-type wipers, these have a single lip that scrapes dirt, dust, and moisture from the rod, preventing contamination inside the cylinder.
Wipers that meet MS28776 fit dash size grooves specified by the standard.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Heavy Duty Shaft-Mounted Rotary Seals
Side 1
Side 2
Profile
These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F. Also known as V-rings and flingers, they protect shaft bearings by blocking dust and other contaminants while retaining lubricant. To install, stretch the seal over your shaft and press it firmly against the face plate.
Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Oil-Resistant Rubber Sealing Washers
These washers surpass other rubber washers when it comes to withstanding oil, grease, and fuel. They create a light duty seal around fasteners to prevent fluids from leaking and damp vibration.
Viton® fluoroelastomer and fluoroelastomer washers withstand oil, chemicals, and high temperatures better than neoprene washers.
FDA-compliant washers are safe for direct contact with food.
