Need O rings for the pump in a baxi 105e instant

[galthop]

I found that my boiler is leaking from where the pump is screwed in. The leak is from the housing around the top screw (there are two screws holding the pump in - one at the top right and one at the bottom).

I think it is the o ring that has failed and I'd like to know where I can get a replacement from. I've done a search online but I can't find any.

Thanks for reading.

Thanks for the suggestion. As I'd have to drain the system, I'd prefer to have new O rings ready but I don't know what size I need.

Just buy them as a spare part, then you get the correct material. If you guess you'll get it wrong.

They'll quite possibly still leak though!

Is there something else I need to do to make sure it does not still leak?

They are the part number you said, but they are not listed for my boiler.

Yes that's the part number.
