Peugeot 307 2.0 HDI - heater pipe seals - T120

I've just changed the heater matrix on a 307 and there's a leak where the pipes attach, I did grease the 'O' rings before refitting but it looks like they need to be changed. Peugeot only sell them as part of a pipe kit -£60 +VAT! Does anyone know what size they are please.

You have the old matrix so measure the diameter of the pipe and check with your local motor factors. Regards Peter

Thanks for the suggestion but that only gives me the I/D of the seal, I'm aware that I can strip down again & measure the old seal but I was trying to avoid that.

I know that but the motor factors may be able to offer you at least a couple of OD's. I doubt the 'O' ring is a special to type size. Regards Peter
