## Description

Brass 2nd Stage Quick Disconnect - Add a quick-disconnect to most regulators or full face mask

Review: Nice
Review: 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.

- Add a quick-disconnect to most regulators or full face mask
- Installs between low pressure regulator hose and second stage

*by L***N on 18 January 2018*

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.
