OMS Workhorse regulator

[andrep1]

Hello.

Couldn't find the OMS workhorse maintenance manual. Anyone know the normal range of IP ? I'm currently sitting at 130 psi.

And by any chance, anyone know the size of the nut that retain the air inlet and filter in the DIN connector on the 1st stage ? See image below, that nut (right under the oring) that is contained in a circular space.

Thanks in advance and as always, much appreciated

Hi Andre,

If I'm not mistaken, OMS regulators were manufactured by Ocean Divers Supply (or is it Systems) same as several other brands like Dive Rite, HOG, Oxycheq, etc. Find a manual from one of those brands for a model that most closely resembles your's. The tooling will probably be metric so a guess would be 19mm for the fitting in the above picture.

Most regulators use an IP of around 135 +/- 10 psi, but again a manual from one of the regs I listed above should tell you.
