DIN or A-clamp first stage?

Most of our divers prefer DIN fitting on the 1st stage regulator. A DIN regulator has a threaded post which screws into the inside of a DIN tank valve and has no additional metal or braces that run behind the valve. This, together with the position of its o-ring, creates a more secure seal on the tank.

YOKE (or A-Clamp) 1st stages have an oblong metal brace that completely encircles the tank valve when in place and is screwed down on the tank valve when the yoke screw is tightened.

Both regulators seal to the scuba tank through an o-ring where the o-ring on a Yoke valve is in the tank valve itself as opposed to DIN regulators with their own o-ring.

DIN fittings are commonly accepted as more secure, but Yoke valves are common throughout North America and recreational tourist destinations. A DIN regulator can be adapted to Yoke valves by using an A-clamp adapter for travel.
