:: FAQ

SSiC or RBSiC for mechanical seals?

SSiC (pressureless sintered) for highest corrosion resistance and lapped sealing faces; RBSiC for larger, complex shapes at lower cost.

Can SiC seal faces be lapped flat?

Yes — sealing faces lapped to 1–3 light bands (helium leak-tight flatness).

How does SiC handle abrasive media?

Its extreme hardness makes it the default choice for slurry and abrasive pump service.
