XS Scuba Brass 2nd Stage Quick Disconnect

I love these disconnects. Well built and always work. I disconnect my second stages and take them with me on a multi day dive trip. Leave my plugged 1st stage and hoses with my BC on the boat for the dive shop to rinse and clean. Because the hoses are sealed with these units disconnected, I don't have to worry about improper rinsing of my second stage regs which I clean back at the hotel... my way. Additionally, nobody will steal my regulator without the second stages attached. I have expensive regs, so it's worth the extra effort. Been diving for over 40 years (2,000+ dives) and I appreciate good, well built equipment.

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.

Excelent product and good quality!

Purchased for swapping between my 2nd stage reg and my FF mask without having to remove the hose with a wrench. Locking collar is a great idea to prevent accidental disconnects. Had to purchase 2nd male fitting, but worth the cost.

Has never failed, very durable. Make swapping out regulators very easy.

The locking feature is a must, i find turning the collar little difficult w dry gloves on. At close to half price of omni swivel, i feel lile this feels better quality. Omni is little lighter and smaller. But mine lasted 2 years before it started to leak and by the end it was wasting alot of air. I tried to replace o rings but seems to use rare size o rings... anyways ive switched over and so far enjoy using this quick release more. Definetly easier to connect w air pressure already on than omni.

The XS Scuba connectors will connect to both the male and female ends of the non check valve equipped Omni QC6 connectors. However, the male Omni connectors with check valves are approximately .007" larger in diameter than the XS Scuba male connectors and the XS Scuba female connectors will not fit. If you need to connect / interchange with these Omni male connectors with a check valve: OSI-QDM-CV; OSI-QDM-CV-YM; or OSI-QDM-CV-ZF; do not get the XS Scuba connector.

Awesome product! I bought this to allow for gas switching with my OTS Guardian Full Face Mask. This fits perfect on the regulator. The female end has a locking screw to prevent accidental removal. It can easily be used with gloves, it's a good size. The quick connect can be used while under pressure and the female end will not leak if disconnected. I need to buy more female ends to use these for sidemount diving.
