Totally interchangeable with Style PS1400 PTFE piston seals, Style PS1500 piston seals are molded from tough 60 Shore D durometer polyurethane. During the molding process, a .002” thick band of molybdenum disulfide is molded into the outside diameter of the seal ring for reduced friction. PS1500 piston seals are easily stretched over the piston and recover rapidly with the elimination of the “cold flow” characteristics found in PTFE seals. Piston diameter “I” dimensions are given for pistons without wear rings.
60 Shore D Durometer | Polyurethane Material | 3.606 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Piston diameter “I” dimensions are given for pistons without wear rings.
15% Glass Filled PTFE Material | 1.723 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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 | 5 1/4 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Molded from filled PTFE and machined to close tolerances, these seals feature low friction and excellent wear characteristics. Nitrile rings are used for energizers.
70A Durometer | PTFE Material | 29 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Designed to fit on one or two piece pistons, this piston seal employs a nitrile seal for high sealability, nylon split back-ups for extrusion resistance, and two split bearing rings. No further support bearings are required.
70A Durometer | NBR Material | 60 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
A heavy duty double-acting assembly, the capped piston T-seal exhibits excellent sealability, extrusion resistance, and wearability. T-seals with “BR” suffix utilize a Bronze Filled PTFE cap instead of the standard Glass Filled PTFE cap.
PTFE; Nylon; Rubber Material | 3.52 in Nominal Inner Diameter | Capped Piston T-Seal
Features
- Glass-filled PTFE cap, nylon back-up, rubber energizer
Molded from tough, wear resistant 55D polyester, these seals are for light to medium duty applications and are interchangeable with the style MPS seals of the same dimensions. Nitrile rings are used for energizers.
55D; 70A Durometer | Polyester Material | 64.5 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Piston diameter “I” dimensions are given for pistons without wear rings.
15% Glass Filled PTFE Material | 2.223 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Molded from 93 Shore A polyurethane with a 70 Shore A energizer, this seal utilizes the same groove dimensions as a standard o-ring or T-seal. One or two Style 575 back-up rings may be used for wider grooves. Extrusion resistant by design, this seal is also resistant to rolling and twisting. Installation is an easy two step snap-in procedure with no need to re-size before insertion into the bore. Piston diameter “I” dimensions are given for pistons without wear rings.
93A; 70A Durometer | Urethane Material | 3 1/8 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Specifically designed as piston seals, these u-seals are engineered to seal on their outside diameter. They offer extended, service life and maximum reliability in piston sealing.
92A Durometer | Urethane Material | 3 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal
