TOTO THP4037 – Frequently Asked Questions
1) What are the dimensions of the TOTO THP4037 foam gasket?
The THP4037 is a foam gasket with an outside diameter of 50, an inside diameter of 47, and a height of 2 as published by TOTO. That works out to a thin-walled ring, roughly 1.5 of wall thickness between the OD and the ID, so it seats around a stem or shaft of about 47 rather than sealing a flat face.
2) How do I confirm THP4037 is the right TOTO gasket for my fixture before ordering?
Match the part number and the ring size. TOTO publishes this one as THP4037 with an OD of 50, ID of 47 and height of 2. Pull the old gasket and measure across it: if the bore it slips over is about 47 and the recess it drops into is about 50, it is the same ring. TOTO uses a lot of visually similar foam rings across bath fittings, so the measurement is what settles it, not the look.
3) Is TOTO THP4037 the gasket itself or a complete stem assembly?
It is the foam gasket only, a single sealing ring. Ordering THP4037 gets you the gasket, not a stem, cartridge, or trim kit, so if the stem or valve body is also worn you need to source those separately.
4) Can I substitute a standard rubber O-ring for the TOTO THP4037?
Not a like-for-like swap. THP4037 is a foam gasket, not a rubber O-ring, and its section is square rather than round: 1.5 of wall between the 47 ID and 50 OD, with a 2 height. Foam compresses and rebounds differently than nitrile, so an O-ring cut to the same bore will not load the same way in the recess. For maintenance stock on TOTO bath fittings, order the foam part by number.
5) Does the THP4037 gasket come in more than one size or finish?
One configuration only. THP4037 is a single part number with no size or finish choices behind it, so there is nothing to specify on the order beyond quantity. Property managers stocking multiple TOTO bath fittings should order per fixture rather than assuming one ring covers the range.
