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 | 45 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 | 86 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 | 125 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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 | 119 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
The MPSU300 is a compact, double-acting piston seal consisting of two parts: a urethane sealing ring with a pronounced sealing edge and a rectangular nitrile energizer to prevent the seal from twisting within the groove. It also has low friction and smooth operating movement even at low linear velocities.
94A; 70/80A Durometer | Urethane Material | 37 MM Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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.
97A; 70A Durometer | Urethane Material | 44 MM 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 | 4.108 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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.
