OmniSwivel Quick Disconnect Female to 9/16-18 Male
- Positive locking prevents accidental disconnection
- Automatically seals on Female QD when disconnected
OmniSwivel International offers high-flow performance (unlike a typical BC quick disconnect). The slider has 9/16-inch male threads that attach to a standard low-pressure regulator hose and accepts the nipple with a positive locking mechanism which prevents accidental disconnection, and which automatically seals when disconnected. The nipple fitting attaches to the standard 9/16-inch male threads found on most second stages.
