Kitchen mixer manufacturer, anyone?

Hi guys

Could anybody give me some idea as to who makes this mixer-tap. It needs 2 new O-rings and I was unable to obtain the exact size as the original. Thanks for any advice.

Thanks, Sam, but I have that very kit and another in addition. All the O-rings are too thick; I have tried several but it is then impossible to get the spout back into the tap body.

Many out there just like that but looks a bit like a Hudson Reed to me.....regards Turnpin

Borrow a pair of vernier calipers. Take an o-ring out (assuming both the same). Measure internal diameter of groove. Measure Width of groove.
The O-rings you'll need are sized ID (internal diameter first) so for example if the internal dia is 24.00mm you'll need a 24ID O-ring. If the groove is 2mm wide, you'll need approx a 1.8mm section o-ring, maybe 1.7mm.

So you'll be looking for 24mm x 1.8mmm O-ring. BTW, BIGGER section is NOT better. An o-ring only needs to be compressed 10% (so a 1.8mm section gets squashed to 1.68mm) to do its job perfectly

If you have a 2mm section o-ring that's 20mm ID that will also possibly fit as they stretch a very long way. However, it will not last too long and will eventually snap. It may however get you out of a leaky hole in the short term.

ALWAYS leave a gap in the o-ring groove when the o-ring is fitted. Because as the o-ring is squashed in, there must be somewhere for the squashed material to go away. Having nowhere is why you cant get what you have to fit. Push hard simply slices chunks off the o-ring.

When fitting, use SILICONE grease to lube. Never petroleum grease or similar.

You are also looking for either Nitrile or EPDM material. EPDM is more robust, Nitrile cheaper. DO NOT use VITON. It's unsuitable for potable water.

Hayes (UK) do nitrile O ring sets in both metric & imperial sizes

turnpin: Thanks for the tip but HR maintain that it is not one of their own.

YorkshireDave: Some very useful advice here, Dave. Unfortunately I was asked to look at the tap issue whilst in the middle of another job so did not have calipers. Usually if I am unable to supply an O-ring from my own kit/s then one of our plumbers’ merchants will match with the correct size. The O-rings in this case are unusually thin (1.5mm or less) and could not be supplied by anybody. Next step will be to get the digital calipers out of the box.

Tim S: Is that Hayes Plumbing at West Drayton? If so it seems that their website is under maintenance. Thanks in any case.
