Common Questions

Will this kit fit my assembly?

The RK212-350 fits 2-1/2" and 3" sizes of Model 350 / 450. Kits are size- and series-specific, so match the model stamped on your valve body or cover before ordering.

What's included in this kit?

This is a o-ring / seal kit -- it carries the factory parts for that subassembly only, not a whole-assembly rebuild.
