hiwhat size o-rings does it take on the valve side also the regulator side? maybe they could add this info with the correct o-ring type and hardness for the gas and pressure used, or sell 10 of each pack along with the valve. then no miss informed any more just more happy divers.
The sizes are standardized in the industry on purpose. The face of the yoke connection on the regs is the same and as such the valve outlet O-rings are uniform. The same applies to the inlet O-rings. The only change in size would be for the now less common 7/8" valves.
a standard yoke valve has a dimple on the back to accommodate the tip of the screw on the regulator yoke. a standard din valve does not have such a dimple but is flat on the back. thus, while the will allow the regulator yoke to fit on the o-ring, the pointed screw will be in contact with the flat back of the din valve. because the tank pressure will be focused through a pointed screw in the back, is this modification safe or might it cause the valve to crack? also, because the valve lacks a dimple on the back, wont the yoke of the regulator be more prone to slip if the reg were bumped? im concerned about safety here. i very much like the idea of this product as i own 4 din tanks and am constantly having to reconfigure my regulator between rented yoke tanks and my own din tanks. also, the local dive shops dislike having to fill din tanks. it would be great to use s in all my tanks. thanks!
