Frequently Asked Questions

What is a hydraulic seal?

A hydraulic seal is a component used to prevent leakage of fluid in hydraulic systems. It ensures pressure integrity and protects components from contamination.

What is the difference between O-rings and X-rings?

O-rings have a round cross-section and seal radially. X-rings (Quad-rings) have an X-shaped cross-section, offering four sealing points and better performance under dynamic conditions.

What is the oil seal used for?

Oil seals prevent lubricant leakage and keep contaminants out of rotating shafts in engines, gearboxes, and industrial machinery.

What materials are used for O-rings?

Common materials include NBR (nitrile), FKM (Viton), silicone, EPDM, ACM, and PTFE. Each offers different resistance to temperature, pressure, and chemicals.
