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 | 53 MM 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 | 47.5 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 | 139 MM 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 | 2 7/16 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 | 3 11/16 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 | 7.16 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

The Style TP-L seal is a zero drift piston seal for bi-directional pressure applications. The locking anti-extrusion rings provide for an easier installation. It is designed to retrofit O-Ring and standard T-seal grooves. The 70 Shore A NBR is designed specifically for performance in compression type dynamic seals. Other features include a net molded dynamic sealing surface and backup chamfers.

70 Shore A Durometer | Buna-N Rubber Material | 2 5/8 in Nominal Inner Diameter | Piston T-Seal

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.
