Common types of Piston Seals
PCA piston sealPCA seal profile
A robust compact double acting seal assembly designed specifically for one piece pistons. It uses a nitrile sealing element which has proven itself in service to be extremely wear resistant and capable of working most effectively in a wide variety of medium duty applications. The seal is also suitable for two piece piston applications.

Temp. range : -30°C to +100°C (Up to +200°C on request)
Pressure : 350BAR
Speed : 0.5 m/s

Light to medium duty cylinders. Static load holding (boom lifting to hold hydraulic platforms) Compact cylinders

Mineral oils, Water soluble & Water glycol fluids

PCQ piston seal
PCQ seal profile
PCQ seals are constructed from polyurethane and NBR. The assembly of a PCQ piston seal is relatively straight forward because the material is elastic and the seal only needs a small housing. Although useful but not essential, lubricate the seat and the gasket using the same fluid as in the system or a chemically compatible lubricant.

Temp. range: -30°C to +100°C
Pressure bar: 0 to 250 BAR at 60°C
Speed: 0.5 m/s

Mineral oils

PCR piston seal

PCR seal profile
A robust compact double acting seal assembly suitable for one piece pistons. Fabric reinforcement with high mechanical strength, optimum thermal stability and lubricating properties. The small radial dimension of this type of seal, together with anti-bearing / anti-extrusion rings enable them to be assembled onto one piece pistons.

Temp. range: -30°C to +100°C (Up to +200°C on request)
Pressure: 350 BAR
Speed : 0.5 m/s

They are intended for use where housing space is at a premium and in semi severe application. Straightforward and quick to assemble.

PEE piston seal
PEE seal profile
Double acting NBR piston seal for one piece pistons, incorporating Polyester anti-extrusion rings & POM bearing rings.

Temp. range : -30°C to + 100°C (Up to +200°C on request)
Pressure : 350 BAR
Speed : 0.5 m/s
