TOTO THP4038 – Frequently Asked Questions
1) What is TOTO part THP4038?
THP4038 is a TOTO sealing part for bath and washroom fixtures, supplied as a single-piece replacement ring. It is a plumbing repair component, ordered by the TOTO part number THP4038 rather than by a generic size.
2) Can I substitute a hardware-store o-ring for TOTO THP4038?
Order by the TOTO number. THP4038 is a TOTO-specified seal for their bath and washroom fixtures, and TOTO seal sizes are matched to the groove in their own valve and fixture bodies, so a generic ring that looks close will often weep or extrude. If you are rebuilding a TOTO fixture, buy the THP4038 by part number.
3) Does the TOTO THP4038 come in more than one size or option?
No options to pick. THP4038 is sold as one configuration with a single part number, so there is no size, material, or finish choice to specify when ordering.
