Hi Guys, I know these are 30mm, but can anyone measure one exactly for us please ? The sealing lip dia.

Wanting to see if it will work in my Pro Elite, which needs a short stroke head made up and fitted (will try around 60mm stroke and work up - I'm guessing 65mm worst case). However, as the PE seal isn't very secure, I may as well machine it for a more secure (and far easier to obtain) HW seal.

TIA - JB

(and no Tony, it won't be done in time for the bash !)
