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.
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.
A two-lip design means that these wipers also function as a rod seal.
These rod wipers are also known as U-type wipers.
Made from MDS-filled PTFE for a slippery surface, these wipers allow rods to move three times faster than other rod wipers.
These wipers seal against the cylinder housing to prevent contaminants from entering between the outside edge and the housing.
Replace wipers in open-groove cylinders—these wipers have an integral steel case so they press fit into the groove around the rod.
These seals have a metal case that creates a tight seal when mating with smooth surfaces.
Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing.
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.
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.
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.
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.
Built for small circulation and dispensing pumps, these seals have short springs.
A slippery PTFE surface allows these seals to function at speeds at least 25% faster than other rotary shaft seals.
Multiple internal springs ensure these seals keep the sealing surfaces in contact in demanding applications, such as agricultural, chemical, and mining pumps.
These seals are commonly used in well, sump, and displacement pumps.
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.
These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F.
Install these seals faster and with less technical expertise than other mechanical shaft seals that come in two pieces. They come with their seal and seat already assembled.
These kits include the rod gland with all of the seals installed.
Replace all the seals on the rod end of a hydraulic cylinder.
Replace all the seals on the piston of a hydraulic cylinder.
