TOTO THP3132 – Frequently Asked Questions
1) What size is the TOTO THP3132 O-ring for the low flow aerator nozzle?
TOTO's THP3132 is an EPDM O-ring with a 14.8 mm inside diameter and a 2.4 mm cross-section. Measure the groove in your aerator housing against those two numbers before ordering, since the seal only works if the ID seats on the nozzle and the 2.4 mm cord fills the gland.
2) My TOTO faucet aerator is leaking around the nozzle - is THP3132 the right replacement seal?
If the leak is weeping from the joint between the aerator nozzle and the spout rather than out of the spray face, the O-ring is the part that failed and THP3132 is TOTO's replacement for the low flow aerator nozzle seal. Confirm the groove takes a 14.8 mm ID ring with a 2.4 mm cord. A leak coming from the base of the spout or the handle is a different seal entirely.
3) Is the THP3132 aerator part rubber or a metal screen?
It's a rubber sealing ring, not a screen or a metal insert. The material is EPDM, which is the standard elastomer for potable water seals because it holds up to hot water and chlorinated supply. If your aerator is spitting or the flow pattern has broken up, that's usually the screen or the nozzle insert, not this seal. A drip at the joint is what this ring fixes.
4) Does the THP3132 come with the aerator nozzle itself, or just the ring?
What you get is the seal alone. THP3132 is the O-ring only, so if the nozzle body is cracked or the screen is scaled shut you'll need the nozzle assembly as well. Order the ring when the existing nozzle is sound and only the rubber has taken a set.
5) Can I stock the THP3132 O-ring for routine maintenance across a building's TOTO lavatories?
Yes, and it's the kind of part worth holding in a maintenance cart. It is a single EPDM ring at 14.8 mm ID by 2.4 mm cross-section, so one size covers every fixture in the building that uses the TOTO low flow aerator nozzle. Swapping a hardened ring takes minutes and avoids pulling a whole aerator assembly. Verify one fixture against those dimensions, then buy for the fleet.
