The PS1800 provides low friction, high strength piston sealing. The PS1800 also provides double-acting piston sealing in a compact design that meets the requirements of ANSI/B93-32-1973. 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
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.

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.

- Wipers are constructed of fluorocarbon
SB19ES has a 0.75 in ID.
The bushing is Unsealed and made of forged steel. The ball will swivel like a fish eye with 3-5 degrees of movement.
Each Seal Guard Wiper consists of two flexible bronze rings which are held in place by a nitrile cushion ring. The cushion ring absorbs side loads and energizes the wiper to maintain close contact with the rod. Particularly suited for hostile environments, seal guard wipers shave off sand, grift, slag, flux, paint, moisture, chips and slivers. Seal Guard Wipers are long-lasting, self-adjusting, and offer low friction. Seal Guard Wipers can be installed in standard Hercules® Sealing Products “ST” or “D” Style grooves by increasing the “F” gland dimension to the “F” Throat Diameter shown.

Parback® backup ring with a curved cross-section.
Parbaks are contoured on one face to minimize distortion of the o-ring when under pressure. Parbaks should be installed with the contoured face against the o-ring, but reversal does no harm.
90A Durometer | Buna-N Rubber Material | 1 5/16 in Nominal Inner Diameter | 3/32 in Cross Section | Backup Ring
Features
- Excellent extrusion resistance
- Easily stretched for installation
- Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces
