What gas is this being used with? Where exactly is it leaking? Is the O-ring damaged? Is it leaking at the threads where the tailpiece threads into the regulator body?

non-flameable gas

the inlet socket - when the gas come in from

i did something leaking testing, after slowly released gas from the tank into it, then turn off. i can see the pressure is slowly drifting down
then i pour some bubble water near the inlet connection, i can see bubbles forming up

i tried tighten, same.

This looks like a gauge off a welding cylinder.

I'd take it into a business that sells welding gasses and ask them to inspect it for defects. Probably just a bad gasket --- if not the fitting going into the welding cylinder can be unscrewed from the gauge and replaced for a few dollars.

Welcome to the forums.

By the's an acetylene regulator.
It's very typical for the o ring to be damaged (circled in red) like the others mentioned.

i believe it's the rubber issue

the prev img is not accurate, i have posted another more alike to what i have purchased (2, they practically same)

there is no placeholder to put on the o ring. i guess i gonna try gum the o ring onto it somehow.

Since you are not showing us pictures of your gauges and you have not told us what gas you are using we really can't help. Not all regulators use O rings to mate with the cylinder.

Do not try to "gum" anything together. Tell us what this regulator is for and where exactly it's leaking. What material is this regulator processing?
