TOTO THP5181 – Frequently Asked Questions
1) What exactly is TOTO part THP5181?
THP5181 is a TOTO replacement O-ring for the connector valve on the plumbing side of a TOTO fixture. It is a sealing ring only, not the valve body, so you order it when the valve itself is sound but the joint is weeping.
2) I ordered THP5181 expecting a valve. Does it include the connector valve itself?
No. THP5181 is the O-ring for the lower connector valve, a seal component on its own. If the valve body is cracked or the stem is damaged, this part will not fix it and you need the valve assembly instead.
3) Can I substitute a generic hardware-store O-ring for TOTO THP5181?
THP5181 is TOTO's own O-ring for the lower connector valve, sized to that valve's groove and seat. A generic ring of roughly similar size often seats badly and leaks under line pressure, which is why facility and MRO buyers maintaining several TOTO fixtures usually keep the TOTO part number on the shelf rather than matching by eye.
4) Is THP5181 sold in different sizes or finishes?
There is one version of THP5181 and that is the whole range, so there is no size, material or finish choice to make when ordering. Specify the part number and you have the correct ring.
