Jabsco 18753-0238VSC Seal Seat, FKM and Silicon Carbide
The Jabsco 18753-0238VSC is the stationary seal seat in FKM with a silicon carbide seat face, an alternative material version of the Jabsco 18753-0238 seat. It lets you match the elastomer and face material to the liquid being pumped while keeping the same fit as the original. Jabsco uses this part number on specific models only, so match it against the parts list for the model number on your pump plate before ordering.
The stationary seat is the fixed half of a mechanical shaft seal. It sits in the pump housing in its elastomer cup, and the rotating seal head runs against its lapped face. Replace the seat and head together, fit the seat square with light, even pressure, and never touch or scratch the sealing face.

Frequently Asked Questions
Q: How do I fit the seat?
Press it in square with even pressure, using a clean tube or a soft tool that does not touch the face.
Q: Can I reuse the old seat with a new head?
It is not recommended. The faces wear together, so fit a new pair.
Q: What damages a seat?
Running dry can crack it from heat, and grit can score the face.
Q: Which elastomer should I choose?
Nitrile suits oils, FKM suits many chemicals and heat, and EPDM suits hot water and many cleaners.
