Mixer tap re-seating tool

[Alison H]

Hello. This is my first post. I hope someone can help me. My kitchen tap recently started dripping from the spout and the spout is also a bit loose. I removed the spout revealing 2 washers that I changed. I re-assembled the spout but the problem persists. I guess my next option is to re-seat the spout. I have seen tools online for this job but they all seem to have to screw in before grinding. My spout has no thread, it just pushes in. Will these tools be of any use to me please. Much appreciated. Alison

No.
Ultimately one is constrained by the groove.
The compression of the o-ring 10-20% max must be accommodated (with a bit to spare) within the groove tsking into acvount swelling from temp rises etc.
You then look to see which std sizes fit or which you can stretch to make fit.
Thats all why Id like the detail as I can send alison to get her own and they work.

So you knew 1.5mm section would be a piston fit and that any more than this would be squashed to make a seal. From experience, you thought having a section 0.3mm greater in diameter would be about right (and 0.3 squashing is actually about 15% of the 1.8). The slight gap around the radial axis allows the squashed material somewhere to go. I think?

EDIT (Just used an online O ring calculator and got 1.8mm. Is this how you knew?)

Gen didnt know they existed. Would haved saved me hours!
Those were worked out for an early vers of our cartridge 😉

Some taps don't use O rings, but use rubber seals of square section. Unless you know the make and model of tap these are almost impossible to find.

Do you mean an oring of non circular section?
