No, I don't know where to get the proper O ring. I only know where to get a new pump or stem along with the O ring, when I only need an O ring. My gripe is that I can't buy an O ring AT ALL, not that I want to use a cheaper one. If I knew which O ring to get, I wouldn't be asking here. Also for...

No that's not how it is. I asked an ebay seller about the part BEFORE I asked here;

Are you certain this is correct? I ask because I enquired about this part number to an ebay seller and they said it's not suitable.

I will if that's possible. Like I said it appears that you need a trade account. What is it that I need exactly?

Thanks for this but I can't view anything. Seems like you need a trade account.

OK thanks. Yes I've gathered that engineers change the whole part, but I'm not an engineer I'm just someone fixing their own who simply needs an o ring. I'm not using bio fuels.

I'm not sure what cribbing means but I simply want to buy an o ring. I'm not insisting on using an unsuitable one, but I'm not using bio fuels. The problem is I don't know what I need and they don't seem to be available without buying a new pump or stem.

What is the change to bio fuels?

Measuring is the difficult part because obviously you need to measure exactly in the centre. I have a vernier gauge but if you apply any pressure it will mis-shape the ring. Plus you need the ring thickness which I estimate is 1.5mm by comparing to another one, but can't be sure. It's ridiculous...

Apparently not according to an ebay seller.

No that's for the filter. I need one like this:

Thanks for the reply. The burner is an RDB1 70-90. The O ring I need is for the valve stem (well I want one to see if that's the problem, at least - since that's where the leak is). Would you happen to know the spec of that O ring? I've removed it but can only try to measure it and guess since...

Hello. As per title, I need to ID this pump to make sure I order the correct o ring. Presumably 'RBL P' is a series, not one specific model, and the number on the left doesn't seem to be of much use.

Thanks but I don't think fitting new taps would be easier

The obviously missing domed part on the right hand tap? Thanks
