pressure cap

[maffey]

Can anyone advise on correct pressure cap for swirl pot, and where I can get one please. Just fitted new stainless pot and now getting to much water back to expansion tank. My old cap rubbers are a bit worm. My old one has 13 stamped on it but read somewhere should be 15 is this correct, cheers guys.

or the bay ?
