The Style PSC is a double acting piston seal designed to replace o-rings, quad-rings, and T-seals with the same groove dimensions (O-ring dash number). Style 575 urethane back-up rings may be added to either or both sides of the “PSC” to accommodate wider groove widths. The PSC is made of 95A Durometer polyurethane, giving it high extrusion and abrasion resistance. The crowned sealing surface produces a positive seal from vacuum to high pressure. Hercules® Sealing Products also offers a wide base (WB) Style PSC piston seal. These wide base seals have the same characteristics of the standard PSC seals but offer a wider base, eliminating the need to use back-up rings to accommodate wider grooves. Piston diameter “I” dimensions are given for piston without wear rings.
95A; 70A Durometer | Polyurethane Material | 3 1/8 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible. Piston diameter “I” dimensions are given for pistons without wear rings.
40% Bronze Filled PTFE Material | 3.384 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
The PS1400 seals offer low friction and high strength in a compact double-acting piston seal design. The PTFE seal ring, combined with a rubber energizer, assures positive contact with the dynamic surface. The PS1400 is designed to fit ANSI/B93.32-1973 groove standards. Piston diameter “I” dimensions are given for pistons without wear rings.
15% Glass Filled PTFE Material | 3.108 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
O-rings as elastic loops that seal static and dynamic applications. They are used to seal the space between cylinders, pistons, pipes and tubes and can be made from various materials.
70 Durometer | Buna-N Rubber Material | 3 1/4 in Nominal Inner Diameter | 3/32 in Cross Section | O-Ring
Features
- Pressure range varies according to diametral clearance
- Temperature range of -40 °F to -240 °F
Utilizing a sturdy metal case, these wipers are molded from the same high performance urethane used in our Heavy Duty U-seals. Built for severe service, these wipers are capable of surviving hostile environments.
92A Durometer | Urethane Material | 4 in Nominal Inner Diameter
Features
- Used in Heavy Duty U-seals
- Capable of surviving hostile environments
- Molded from the high performance urethane
Molded in PTFE with a rubber energizer, this seal absorbs the shock of pressure spikes to protect the rod seal.
70A Durometer | Filled PTFE Buffer Material | 80 MM Nominal Inner Diameter | Buffer Seal
Style 850 u-seals offer excellent resistance to extrusion and abrasion. The round cross-section expander offers energized sealing from zero to 5,000 psi.
95A Durometer | Urethane Material | 2 1/4 in Nominal Inner Diameter | 7/32 in Cross Section | U-Seal
O-rings as elastic loops that seal static and dynamic applications. They are used to seal the space between cylinders, pistons, pipes and tubes and can be made from various materials.
