Hydraulic seals are essential components in a hydraulic system as they help prevent leaks and ensure the smooth and efficient operation of the hydraulic system.

What are the commonly used hydraulic seals? Hereby show you below:

Hydraulic sealing systems include:

O ring

O-rings are the most commonly used hydraulic seals, and are suitable for a wide range of applications.

Material typically made from NBR, HNBR, FKM, Silicone, FFKM etc.

Piston seals

Piston seals which work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

Typically including SPGW, SPGO made by bronzed filled PTFE+NBR elements.

Rod seals

Rod seals which are external seals that prevent leakage from the cylinder.

Commonly SPNS made by bronzed filled PTFE+NBR elements.

Wear Ring

Wear rings which guide the piston and piston rod in the cylinder and prevent metal on metal contact.

Commonly Phenolic resin material and PTFE material for used.

Wear Strip

Wear strips are widely used in hydraulics, machine tools and mechanical engineering to prevent metal-to-metal contact.

Commonly bronze filled PTFE and phenolic resin material.

Wiper

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.

Commonly PU material.

Spring energized PTFE seals

Spring energized PTFE seals perform reliably in a variety of applications where conventional elastomeric seals fail due to chemical attack, extreme heat or cold, friction, extrusion or compression set.

JST commonly provides PEEK, PTFE filled material for jacket, stainless spring, Alloy spring for energizer.

In Conclusion, hydraulic seal is an essential part of the hydraulic system, and different sealing components can be selected for use according to environmental and application requirements.
