Urban transfer port O-ring size

[toddbrat]

Curious if anyone knows what size O-ring the Urban uses. I’m getting a loud POP from mine and a wee puff of air, pretty sure it is time to replace it. TIA!

What I was thinking. Maybe it’s just the probe ?

I wish it was the probe. I’ve been in and out of this thing several times over the past few years since I can’t leave well enough alone. The last time I noticed a few nicks in the upper TP oring. I think it finally gave out.

Thanks, yeah I stopped by harbor freight today and picked up a metric set. Figure I’ll tear into one day this week.
