	Pip Rings The PIP seal combines a Type B loaded u-cup (PolyPak) with a pressure inverted pedestal which will convert the Type B seal into a bi-directional device.The PIP seal needs only a single groove and can be installed on one-piece pistons in most cases, thus saving space, increasing the bearing length of the piston and reducing the number of piston components involved. A PIP seal can be installed in a bi-directional seal system replacing two standard PolyPaks at a considerable savings in both machining and seal cost. Note: Some minimums may apply.

If you can’t find something you’re looking for, give us a call at 800-445-7803.
	"Q"-Rings A "Q"-Rings is a four-lobed seal. The four-lobed design provides twice the sealing surface of a comparable standard O-ring and because of this double-seal action, less squeeze is required to maintain an effective seal. This reduction in squeeze means less friction and therefore, improved seal life. Unlike O-rings, where parting lines are on the sealing surface, Q-ring seals' parting lines lie between the lobes, away from the sealing surface. This design eliminates the problems of leakage often resulting from a parting line's irregular surface. Q-ring seals can be used as compression-type seals in high speed rotary applications, eliminating the need for costlier spring-loaded seals. They offer low friction for long life in hydraulic systems with speeds of up to 900 FPM (4.5 M/Sec.). Note: Some minimums may apply. If you can’t find something you’re looking for, give us a call at 800-445-7803.
