Leaking from first stage

[EliotD]

My tri-metal is leaking from the first stage, behind the DIN connector, is this a common problem and what can I do to resolve it?

[H2Andy]

do you mean that air is coming out through the metal?

or is the leak through the DIN valve itself?

[cerich]

at the base of the din connector there is a oring.

Some divers "twist" the reg to start to unscrew it instead of just using the Din handwheel. This sometimes will back off the din fitting causing what you describe. All it needs is the DIN fitting removed, new oring and then reinstalled to the proper torque specs and you are good to go.

It's not incommon with all makes of DIN regulators.
