Hi all, hoping for some help with replacing an old leaking toilet pan connector. This is the connector coming out of the wall and the rubber has started to perish so it's leaking, the second picture shows the plastic ring that fits over the rubber. I can't seem to find anything like this but maybe I just don't know what it's called?
Ideally I'd like to just replace the rubber and ring as the plastic part appears to be bonded to the main pipe.





Thanks for any help.

It's just a toilet pan connector, if the rubbers are available separately or not, I'm not sure, but you could just buy one of a similar dimension and rob the rubber gasket from it. should do the job.

You’re right with pan connector, or wc coupler - there are many different makes though.
That looks like a solvent weld type. All the sheds will carry them and they’re cheap enough to try buying one for parts

Make absolutely sure it’s pushed fully home on the chinaware before you flush it, these things can start a nasty drip which builds up over time on/under the floor. I’d probably leave a plastic box and some kitchen roll under it for a few weeks after you reassemble to ensure it’s totally watertight.


Yes, I have had one leak… frown

Thanks all, my problem seems to be that the plastic pan connector (on the back of the toilet) pushes into this pipe coming out of the wall and without a new rubber seal I can't get a waterproof seal - I'm looking on Screwfix and Wickes but if there's a better online site I'd be keen to find it.

I came across a 4" extension pipe that can be cut to length and that has allowed me to ignore the old rubber seal on the wall end and push fit the new pan connector straight into it. The toilet has been in for >25 years and I'd say it was a bit of a bodge given how badly it fitted when I took it apart but I'm pleased with how it's turned out.
