Help Identify Mixer Tap - Leaky o-ring!

[seajays]

Hi - we have a disabled toilet with a small lever operated mixer tap which is leaking continually.

The tap has some very small rubber o-rings internally which need replacing, however they seem to be a non-standard size and I'm having difficulty getting hold of them. The o-ring cross-section is 3mm, with a central hole of about 2.5mm making the whole thing only 8.5mm across the diameter.

If anyone can tell me where I can get o-rings of that size I'd be grateful!

Alternatively can anyone identify the manufacturer so that I can contact them - this is the logo but I'm not sure what it is (it looks like "AS" so I thought Armitage Shanks, but I can't find any trace of them using a logo like that online).

seajays,

Go to the Armitage Shanks site.

click on the home owners tab

click on the fastpart spares. right hand side very top of page

click on tap spares

70 odd pages of taps all with pictures (in colour)

If you cannot find your tap there I would by some new ones

Thanks for that link Dave.

Unfortunately it doesn't seem like they have the spares for that tap.

It seems an awful (and expensive) waste to have to replace the entire tap, for the want of two tiny rubber o-rings!

Measure the exact size, OD, ID, and thickness and go to one of the many sites that supply O rings. Just Google O rings.

I have - the size appears to be non-standard as it does not fit the size of any of the BS/ISO o-ring sizes I've been able to find.

It's the internal diameter that's the problem... nothing comes close to an internal diameter of 2.5mm, with a cross section of 3mm (or nothing that I've found). Anything with that cross section, seems to start with an internal diamter ("hole") of about 3.5mm - which is clearly way too big.

I'm afraid this is what it's like today with all taps - we are now in a throw away society.

At one time, not that long ago all taps had standard washers and a packing gland (no 0 rings) which you could repair until the cows came home

Not so today

Servotech,

What does the o ring actually do, i realise its a seal but is it on a moving part? If the rubber or whatever its made of is hard then if you have the skill try cutting down a tap washer. There are washers with no holes in the center so it can be drilled to size and i've ground them down against a disc cutter with a spindle through the center hole so fingers are away from the disc.

It actually provides the seal on a little plunger... this photo shows the innards of the tap, and you can see two little plastic plungers which are pressed down as the tap is turned on, the o-ring goes around the bottom of the plunger so when the tap is off, the spring forces the plunger up, and it creates the seal.

So it would have to be very precise to make the seal appropriately!

I have exactly the same tap and exactly the same problem, have trawled all the websites etc and I can't find them anywhere. Even went to the local hydraulics specialists and they had never seen anything that guage and couldn't find it in their books. If you find one please post back and I'll do the same. I have emailed Armitage Shanks but they haven't bothered to reply yet..

This is the second one of these taps to fail the same way, I gave up trying to fix the last one and just replaced it.

Good luck hunting...

Same here - I'm waiting for a response from their spares website. Problem is I can't wait too long, as we have to get a tap in there, so it's looking more and more like I'll have to buy another if they haven't got back by the end of the week.

The tap is an Armitage Shanks Spraymixa S7445AA and the seal kit is available on part code E960186NU £10.54 excl

Hope you haven't bought a new tap yet...

Haven't tried to buy the kit yet, thought I'd get the post up first....

 

[seajays]

Fantastic - I was on the verge of buying one today (I'd even put it in the online basket), but decided to wait one more day...

Glad I did!!!

Fantastic - thanks!
