So decided that I would fit 2 Aqualung pressure transducer things to my CCR last year . Never been happy with them as I always needed to give the units a slight tug when I turned on the cylinders otherwise they leaked. Today somebody said “ your unit is leaking” . No matter what I did it wouldn’t seal . Did the dive leaking O2 all the time & sent an email of to we’re I bought them from .
The answer came back asking if I had fitted swivel pins !! Oh dear thinks me never even thought about those when I got high pressure hoses out my spares box.
