Tuning Pressure gauges leaking

[F-classmike]

I have five pcp rifles and a pistol. Every time one develops a leak it’s always the gauge leaking air thru the middle .Not from the threads. Every time I hear of gauges failing it seems like they no longer read accurately. Mine still seem to show the pressure accurately but leak air. I usually replace them with gauges from McMaster Carr but had two of those leak as well. Is anyone else replacing gauges because they leak internally or am I just having bad luck. I think I’ve gone thru five or six gauges already. Also any other sources for replacement gauges in the same price range as McMaster Carr.

I've not had any gauges fail (leak) internally, and I haven't purchased anything from McMaster Carr for years, but I don't recall them being all that 'inexpensive.'

But if they are, maybe you are dealing with a 'you get what you pay for' scenario?

When I have had to replace a gauge for some reason, I have generally gone with a replacement from Huma as I appreciate the quality of their products. I think that the $25 I recently paid for one through Utah Airguns (or $24 through Trenier) is a reasonable price to pay for a quality gauge.

Have several guns and compressors with gauges. Never in twenty plus years had one leak internally. I have replaced several because they were reading incorrectly though. Me too on the Huma gauges. I use the Wika gauges they are great.

Who supplies the wiki gauges.

Leaking through the weep hole, is the primary way they fail. Never had them fail other than that.

Exactly how much pressure does it actually lose FROM the GAUGE in 8 hours?

I find it extrenely peculiar for anyone to have such bad luck with leaking gauges that aren't leaking at the threads.

I have a Leshiy that had a Huma gauge on it. My gun started leaking from the gauge area. I noticed the gauge face clear plastic slightly popped out on one side and I could feel a slight stream of air. It was leaking internally somewhere. I replaced with a Wika gauge, all is good now. I've owned probably 15+ pcps over the last 20 years, this is the first time a gauge has leaked on any of my guns.

I had an Airforce Texan gauge leak internally, they sent me a new one free, I found replacement gauges at Amazon and McMaster Carr, all are china made, but some are 1/8" bspp and others are M10x1, you just need to know which one you have before ordering a new one.

Almost hate to say it, but I buy gauges at Aliexpress for 3-4 bucks a piece. China made of course. Never had an issue with them.

Are you sure you're not overtightening your gauges? It happened to me, and they started reading inaccurately.

Four of the gauges that leaked were factory gauges on Marauders and an Air Force Condor. My Condor is loosing about 100 lbs of air in 24 hours. Probably the gauge. I havn’t sprayed leak detector on it yet.

Could be because I’ll top my guns off when I’m done shooting and put them back in the safe with a full charge. Could be in the safe a couple weeks to a month before I take a particular one out to shoot it and notice the pressure is down to 1000. Maybe I should put them away drained down to 2000 lbs. and top them off when ready to shoot.
