Specializing in Metal Ring Seals, Sonkit presents high-quality, cost-effective metal seals.


Sonkit Metal Comma Ring Seals are designed for slow dynamic applications. The tightness with a Comma Ring is greater than with any other metal seal, which is a function of the shaft condition. The surface finish of the shaft shall be mirror polished, and the hardness shall be high enough so that the sliding motion of the seal and shaft does not deteriorate either of them. In addition, we advise to silver plate Comma Ring for better tightness, reduced friction and wear.
