The PS1850 piston seal can be used interchangeably with the PS1800 style piston seal. This seal provides improved heat resistance for demanding applications. Piston diameter “I” dimensions are given for pistons without wear rings.
Bronze Filled PTFE Material | 7 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
The PS1850-V piston seal can be used interchangeably with the PS1800 style piston seal. This seal provides improved heat resistance for demanding applications. Piston diameter “I” dimensions are given for pistons without wear rings.
15% Glass Filled PTFE Material | 7 1/4 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Some PS2000 piston seals utilize a round instead of a square energizer. Also, piston diameter “I” dimensions are given for pistons without wear rings. Many sizes shown are completely interchangeable with style PS914 piston seals.
Glass Filled Nylon Material | 3.462 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
This seal, molded from high grade 55D polyurethane, may retrofit the PS1800 seals, considering all dimensions are comparable. This seal material, with a high degree of memory, stretches over the piston and snaps in the groove for immediate assembly. These seals also feature low friction and high abrasion and extrusion resistance which helps to eliminate assembly damage. Piston diameter “I” dimensions are given for pistons without wear rings.
55D Durometer | Glass/PTFE Filled Polyurethane Material | 0.691 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
This two piece piston seal design comes made with a heat-stabilized, thermoplastic step-cut ring along with a profiled NBR energizer. This product offers extreme strength and resistance to extrusion, a very high resistance to abrasion, and ease of installation thanks to the step cut design and chamfered edges. The design also allows the seal to pass over ports without damage and offers greater resistance to surface roughness in comparison to any elastomer seals. The profiled energizer offers improved dynamic sealing ability, responding quickly to pressure changes and providing excellent sealing characteristics under a wide range of pressure conditions.
Glass Filled Nylon Material | 2.692 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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.

T-Seals combine a resilient sealing ring with a hard, split back-up ring on each side of the sealing element. The assembly installs in a standard o-ring groove. T-Seals are non-spiraling and extrusion resistant to 5,000 psi with improved tolerances. Intermediate and Wide Base T-Seals are designed to fit MIL-5514F o-ring glands only and interchange with 1 o-ring / 1 back-up ring and 1 o-ring / 2 back-up ring grooves, respectively.
Buna-N Rubber Material | 2 1/2 in Nominal Inner Diameter | Piston T-Seal
A double acting piston seal with many features: Two compact seal edges to concentrate the load against the dynamic surface, a cavity between the two external seal edges to retain fluid (reducing friction and wear), side grooves to allow pressure to load the energizer in all working conditions, high sealing performance at low pressure, excellent wear-resistance, and high resistance against extrusion.
