TOTO THP5557 – Frequently Asked Questions
1) What exactly is TOTO part THP5557?
THP5557 is a TOTO valve cap O-ring, a small sealing ring that seats on the valve cap of a TOTO plumbing valve. It is a replacement seal only, not the cap body or the valve itself, so if the cap or cartridge is cracked or worn you need that part as well.
2) Will the TOTO THP5557 O-ring fit any brand of valve, or only TOTO?
Order it for TOTO valves only. THP5557 is a TOTO-specified valve cap O-ring, sized to that manufacturer's cap. Generic O-rings of a nominal size often seal on the bench and weep under line pressure, so for a TOTO trim or valve repair, match the factory part number.
3) I manage apartments with TOTO fixtures, is a THP5557 O-ring something worth stocking?
Yes, for a property running TOTO valves it is a sensible shelf item. The valve cap O-ring is the part that typically causes a slow seep at the valve, it's inexpensive to hold, and having one on the truck turns a callback into a five minute repair instead of a return trip. THP5557 is the TOTO part number to order against.
