XS Scuba Second Stage Quick Disconnect

seals are good quality but would have like to see thicker thread walls on the male fitting, the aluminum feels weak. The female fitting is of good build and I like the threaded lock mechanism. SS fittings by xs scuba would be a more robust option for the price.

Nice

These are fantastic. The release is very easy to grab and pull back, even with thick gloves. Hard to tell in the pic, but the release collar is a narrow flange that protrudes out a fair amount. It also has a lock (the black section), which you can tighten up against the release mechanism (by turning it like a nut) to prevent accidental release, which I did not expect -- very pleased about that. Also did not realize that this is the type which you can just press on to connect, without having to pull back on the collar first. The parts feel very solid and well made -- I expect it will last a long time. I bought two sets: one for my primary 2nd stage full face mask, and the other for my pony bottle. That way I could switch to my pony in an emergency, without having to remove my full mask. I haven't had to do that in the water, but have tested it at the surface, with the air on.

My wife and I upgraded to full face masks. Very east to install. An earlier review was correct. It would be better if you order two additional receivers to mount on a spare regulator in case we want to switch back to our regular regulator quickly.We’ve already tested them in our pool, (6’ deep) with zero leaks. After some more training with the new masks in the pool, we will be trying them and the quick connections in deeper water.

I have attached this to my Ocean Reef FFM and LP hose. works perfect and makes the mask much more easily friendly. I highly recommend for anyone who may regularly switch between regulators like I do. The pieces are very high quality, very easy to install and know how to use. They will last a long time if you take care of them and rinse them good after each dive.
