Common Questions
- Will this kit fit my assembly?
- The RK4-375ASTCK1 fits 2-1/2" and 4" sizes of Model 375AST / 475ST. 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 #1 check assembly repair kit -- it carries the factory parts for that subassembly only, not a whole-assembly rebuild.
