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.
Rated for pressure up to 10,000 psi, these leather U-cups handle over 80 times more pressure than our Buna-N U-cups.
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.
Also known as Type B seals, these U-cups are wider than our other O-ring-loaded U-cup seals for better stability and fit in wider grooves.
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.
PTFE gives these seals a slippery surface that facilitates rod speeds over seven times faster than our other buffering seals. They're rated for pressure up to 5,000 psi.
Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our buffering seals.
These seals have a beveled lip that optimizes contact against the rod, while a secondary lip keeps the seal stable.
Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.
Replace the standard O-ring/backup ring combination with a more reliable alternative—these head seals resist twisting and remain stable even in applications with fluctuating pressure.
The slippery PTFE surface of these seals allows rod motion up to seven times faster than our other rod seals.
For use in air-powered cylinders, these seals prevent the piston from slamming against the cylinder body to minimize wear and noise.
A square O-ring prevents these piston seals from rocking in the groove.
PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.
These Buna-N seals are reinforced with cotton thread for strength.
Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston seals.
These rod wipers are also known as U-type wipers.
A two-lip design means that these wipers also function as a rod seal.
These wipers seal against the cylinder housing to prevent contaminants from entering between the outside edge and the housing.
Made from MDS-filled PTFE for a slippery surface, these wipers allow rods to move three times faster than other rod wipers.
Replace wipers in open-groove cylinders—these wipers have an integral steel case so they press fit into the groove around the rod.
These compressors use either a spring clutch or two screws to make incremental sizing adjustments for a secure fit. Use them to ensure smooth insertion of your piston into a cylinder.
Also known as a wrinkle-band compressor, this tool has fewer points of contact than other compressors for less friction.
Push the lever and this compressor instantly releases for easy removal.
Reduce the risk of distorting and breaking piston rings during installation and removal.
Install flexible seals, wipers, and O-rings.
An extended spring on these seals accommodates variations in seal cavity length and pump misalignment.
With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length.
These seals are commonly used in well, sump, and displacement pumps.
Built for small circulation and dispensing pumps, these seals have short springs.
Multiple internal springs ensure these seals keep the sealing surfaces in contact in demanding applications, such as agricultural, chemical, and mining pumps.
Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing.
A slippery PTFE surface allows these seals to function at speeds at least 25% faster than other rotary shaft seals.
Commonly used in mixing and grinding equipment, conveyors, and construction machinery, these two-part seals withstand exposure to abrasive material.
Designed with an extended lip, these seals have the flexibility to accommodate shaft misalignment up to 0.125". They're also known as clipper seals.
These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F.
Also known as grease seals, these are designed to retain thick lubricant at low pressure. They have a light grip on the shaft that creates less friction than spring-loaded seals.
Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.
These seals have a metal case that creates a tight seal when mating with smooth surfaces.
Swap out old seals without disassembling components—these seals come split for easy installation. They're also known as clipper seals.
Made from Buna-N for excellent resistance to oil and grease.
Replace all the seals on the rod end of a hydraulic cylinder.
Replace all the seals on the piston of a hydraulic cylinder.
These kits include the rod gland with all of the seals installed.
Made of soft expanded PTFE, these gaskets are virtually chemically inert.
Resist boric acid, citric acid, isopropyl alcohol, fuel, oil, and transmission fluid.
Also known as Hochdruck, these graphite gaskets have stainless steel layers for added strength in hot environments.
Also resist aliphatic hydrocarbons, such as ethylene.
