Piston diameter “I” dimensions are given for pistons without wear rings.
Glass Filled Nylon Material | 4.74 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Compact and easy to install, the Style PSA-65 piston seal is a simple and economical design for pressures up to 3,000 PSI. The assembly consists of a nitrile rubber seal and two polyacetal bearings to support the piston. For 1-piece pistons.
Nitrile Material | 2 1/8 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Our Style PSU piston seal, or uniring, is a laminated one piece double acting seal made of cast polyurethane. The tough outer layer is highly resistant to abrasion and is impregnated with molybdenum disulfide to reduce friction. The softer inner layer acts as a static seal and also energizes the OD to make full contact with the bore. This seal may be used to replace an existing Uniring or other seals of the same dimensions – O-rings, O-rings with back-ups, T-seals, U-seals, etc. Piston diameter “I” dimensions are given for pistons without wear rings.
60D & 57A Durometer | Urethane Composite Material | 2 5/8 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 | 3 1/8 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.
Buna-N Rubber Material | 3 5/8 in Nominal Inner Diameter | Piston T-Seal
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 | 2 15/16 in Nominal Inner Diameter | Capped Piston T-Seal
Features
- Glass-filled PTFE cap, nylon back-up, rubber energizer
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 | 3.27 in Nominal Inner Diameter | Capped Piston T-Seal
Features
- Glass-filled PTFE cap, nylon back-up, rubber energizer
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 | 11 in Nominal Inner Diameter | 1/2 in Cross Section | U-Seal
This capped piston seal consists of a filled PTFE cap, a T-shaped NBR energizer, and two split nylon backup rings. It exhibits low friction, high sealability, and excellent resistance to extrusion and wear.
PTFE Material | 60 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 | 49.5 MM Nominal Inner Diameter | Piston Seal
