Questions and Answers for
Hollis Pony Bottle Gauge:
How large is the screw in? The last one I got was to big for my regulator.
(Certified Scuba Instructor at Scuba.com)
The threaded portion of all regulators manufactured in the last 20 years all use a common thread pattern/size. It should fit any current High Pressure Port. If your regulator is older, there is a possibility it is too large as at one time the HP and LP ports were the same size. This was altered for safety reasons.
Pony Bottle Gauge Ideal for deco bottles or back-up air supplies, this miniature pressure gauge provides accurate reading up to 5000 PSI or 400 BAR.
