FAQ

What is the typical pressure rating for a WA type seal?

WA type seals are generally designed for low-pressure applications, typically up to 0.5 bar (7 PSI). For higher pressures, specialized seals or system modifications may be required.

Is NBR material suitable for high temperatures or aggressive chemicals?

NBR (Nitrile) offers excellent resistance to mineral oils and greases at temperatures up to approximately 100 deg C. However, for higher temperatures or exposure to aggressive chemicals, alternative materials like FKM (Viton) are recommended.

What is the function of the garter spring in this seal?

The garter spring provides a constant, uniform radial force, pressing the sealing lip against the shaft. This ensures a consistent and reliable seal, even with minor shaft imperfections or thermal expansion.
