Taipan Remove pressure gauge from mutant

[miksatx]

How do I remove the collar around the pressure gauge. Need to replace o- ring.

Gauge unscrews & collar only comes off then.

Either use correct thin wall socket or the 2 drill shank methiod placing drill shanks snuggly into the flats on gauge flats & Then hold them in vice jaws with gauge face up close to jaws and gently apply rotation to housing. It is what I do

Thanks Motorhead got it changed out and gun back in action. I used the drill shanks and vice.

Just checked date of purchase 8 years that o-ring lasted.
