A961667NU is a pair of Ideal Standard / Trevi cartridge O-ring seals used around the cartridge assembly in a range of basin mixers, bidet mixers, bath and shower mixers, shower valves and associated valve bodies. The seals measure 28.3mm x 1.78mm and are supplied as a pair.
These O-rings provide a seal around the cartridge interface within the tap or valve body. If the existing seals are worn, flattened, split or damaged during cartridge removal, fitting new seals can help restore the seal around the cartridge. These O-rings are not the cartridge shut-off mechanism, so a dripping outlet may indicate a separate cartridge fault.

Lightly lubricating the O-rings with suitable silicone grease during fitting can help them seat correctly and reduce the risk of damaging or twisting the seals.
Check the model code and the dimensions of the existing seals before ordering because the diameter alone does not confirm fitment. If you are unsure which part you need, use our Di Vapor part identification service and we can help.
