First Stage LP Quick Disconnect – Fast Removal of Second Stage, Drysuit, or FFM Hoses

The First Stage LP Quick Disconnect is a premium low-pressure accessory that gives divers the ability to instantly remove an entire LP hose assembly from the first stage. Whether you need to detach your second stage hose, remove your drysuit inflator hose when diving wet, or disconnect a full face mask hose when not using an FFM, this quick disconnect makes configuration changes fast, clean, and effortless.

This quick disconnect threads directly into the low-pressure port on the first stage, allowing the connected hose—second stage, FFM hose, or drysuit inflator hose—to detach completely using a secure, proven quick-release mechanism.

This is especially valuable for:

Public safety divers switching between FFMs and open-circuit second stages

Recreational or technical divers who dive wet some days and drysuit others

Keeping unused hoses out of the way to streamline your profile

Easier rinsing, packing, or storing delicate regulators and hoses
