Tap cartridge identification?

[chinaysa]

Hi - I've got a quarter-turn cartridge that I'm trying to identify please - 35mm x 58mm. It's about 25 years old and uses square profile o rings.... can't find anything online that matches and unfortunately don't have original manufacturer's details.
Many thanks.

Have you tried the toolstation one? Less than a fiver and it can often be made to fit.

Are the O Rings definitely square section or is it because they've been squashed into a square profile groove for 25 yrs?

Think you will find the are just normal as stated by first answer

Definitely square and match the mouldings in which they sit...have checked under magnification

Probably doesn’t matter, usually the orings have to fit in the cartridge but the brass surface of the tap seat is usually flat so the o ring profile won’t matter. ( often has two indents for locating lugs on the cartridge, to index it so the orings sit over the holes correctly as there is not much coverage)
