Along with the Parker System, Sealing Specialists can supply you with many different types of hydraulic seals.
|
PSP Seal, PIP Seal, T-Seal
PSP Seal: The Parker PSP Seal is a Bidirectional "squeeze" type seal ideal for use as a piston seal in fluid power cylinders.
PIP Seal: The Parker PIP Seal combines a Type B Polypak
with a "pressure" inverting pedestalwhich will convert the type
B Seal into a Bi-directional device.
T-Seal: The Parker T-Seal is designed for direct replacement of
O-rings in long stroke hydraulic applications where spiral failure due to rolling of the O-ring in the seal groove has occurred.
Type-B PolyPak
Type-B PolyPak: The Parker Type B or Spring Loaded PolyPak Seals offer new improved sealing. This design will give reduced leakage. The spring allows the seal shell to withstand wider temperature ranges.
Type-J Wiper
Type-J Wiper: Parker Type J canned wipers are designed for press-fit in open face rod wiper glands and do not require additional retention devices
such as snap-rings or face plates.
Standard PolyPak, U-Packing
Standard PolyPak: The Parker PolyPak is a patented precision molded multi-purpose seal. The Parker PolyPak combines an O-ring type synthetic rubber O-Spring with a conventional lip-type seal to produce a unique sealing device
capable of sealing both vacuum, high and low pressure.
U-Packing: Parker 8500 Series U-Packings have the same advantages as the 8400 Series and have the same ID, OD, and cross-sections. The major difference is the long squared off lips of the 8500 configurations.
U-Packing, SCL Seal
U-Packings: Parker 8400 Series U-Packings are especially adapted to low speed-low pressure situations. The compact configuration of the 8400 style and
its inherent low friction make this an ideal pneumatic seal.
SCL Seal:Parker SCL (Special Cut Lip) Seals are unidirectional seals designed for use in reciprocating devices such as cylinders and spool valves.
Snap-in Wiper
Snap-in Wiper: Specially designed heel area of the wiper prevents a fluid buildup from rod seal seepage. As rod seal leakage increases pressure builds to a point where wipers can be blown out of their grooves. Relief slots prevent pressure trapping between rod seal and rod wiper.
