> LP and HP Hose Port Adapters

Most first stage high-pressure ports (including Dive Rite) are 7/16-inch female. A few brands of first stages use high-pressure ports that are 3/8-inch female. We offer 3/8-inch to 7/16-inch hose adapters.

Most first stage low-pressure ports (including Dive Rite) are 3/8-inch female. A few brands have a special low-pressure port that is 1/2-inch female. We offer 1/2-inch to 3/8-inch hose adapters.

Omni-Swivel, LP 2nd Stage: 9/16-Inch M = 9/16-Inch FI

Supplied by OmniSwivel International, this very high quality omni-directional swivel screws inline between the low-pressure hose and the second stage. Offering complete 360° rotation, it allows the low-pressure hose to exit the second stage at any angle you choose. The swivel movement allows the regulator mouthpiece to move without restriction. Moving your head in any direction will not cause the second stage to pull on your jaw. This adapter makes the regulator feel much more comfortable in your mouth on waist-mounted deco and stage cylinders where the hose runs down your chest rather than over your shoulder.

Right Angle Swivel, LP 2nd Stage: 9/16-Inch M = 9/16-Inch FI

The XS Scuba Right Angle Adapter makes your primary regulator hose more comfortable while diving. It installs between the second stage and the regulator hose. It is not a fixed 'elbow', it actually swivels at the regulator and at the hose, but is not an omni-directional swivel and so it maintains its angle and will not allow the regulator to flop around. Placed on a 40-inch primary regulator hose in a single-tank regulator configuration, it allows the hose to route down under the arm and up to the mouth, getting rid of the large hose "arc" that protrudes from the tank around the diver, offering a more streamlined configuration.

70 Degree Swivel, LP 2nd Stage: 9/16-Inch M = 9/16-Inch FI

The 70 Degree Swivel Adapter attaches between the regulator second stage and its low pressure hose routing the hose down the diver's chest and/or under the arm, which increases comfort and streamlining. This low-profile adapter is not an omni-directional swivel and so it maintains its angle and will not allow the regulator to flop around. Sidemount divers use the 70 Degree Adapter to route their hoses down their chest to the bottles eliminating the need to route the hose around the neck.

> High Flow Quick Disconnect Fittings

The quick disconnect system by OmniSwivel International, offers high-flow performance (unlike a typical BC quick disconnect). Each fitting is sold separately and you'll need to determine how many of which fittings you need to build your system. The quick disconnect slider has 9/16-inch male threads that attach to a standard low-pressure regulator hose, accepts the nipple with a positive locking mechanism which prevents accidental disconnection, and automatically seals when disconnected. We offer two different versions of the nipple fitting. One version of the QD nipple fitting attaches to the standard 9/16-inch threads found on most second stages. The other version of the QD nipple fitting screws into the standard low-pressure regulator hose 9/16-inch fitting. Note: the OSI QD system is not compatible with CEJN type fittings.

Adapter, LP 2nd Stage: 9/16-Inch FI = BC Inflator QD Post

Supplied by OmniSwivel International, the regulator quick connection adapter attaches to the standard 9/16-inch threads found on most second stages, where the low pressure hose would normally attach, and the other end has a standard BC inflator male QD post. This tool allows a diver to plug a second stage into the rebreather manual addition hose to allow access to the onboard gas supply. Typically the adapter would be used to gain access to the onboard oxygen but could be used for shallow access to diluent as well. The 2nd Stage Quick Connection Adapter will not supply adequate gas if the diver is deeper than 20 feet.

"EZ" QD Adapter

The XS Scuba QD Adapter converts any standard LP regulator hose to a low pressure QD hose and works particularly well as a drysuit inflator hose. It works GREAT with the Miflex LP hoses to produce an extremely flexible drysuit inflator hose solution. Just push on to attach to the inflation fitting, no need to pull back the collar. However, it still has a positive locking mechanism that requires the collar to be pulled back to disconnect. The large collar makes it easy to remove even with heavy gloves and is a much better solution than the 'hose hat' addons for standard BC inflator hoses. The collar also has a 'flat' area that makes it work very well in tight areas such as next to drysuit inflator valves. This adapter is constructed with chromed brass, delrin and is nitrox ready with Viton o-rings.

Inline Shutoff Valve: 9/16-Inch M = 9/16-Inch FI

This very high quality shutoff valve by OmniSwivel International fits in-line between your low-pressure hose and second stage regulator. The shutoff valve opens and closes very quickly by sliding (ON is toward the Second Stage), and provides positive tactile feedback when operated.

Compact Inline Shutoff Valve

This Asian manufactured alternative to OmniSwivel version of the in-line shutoff slide valve is significantly smaller and a bit lower cost. It also has a different feel to the slide valve operation that requires less force to open and close with less of a positive "detent" (also, ON is toward the hose, not the second stage). As with any cutoff, the regulator first stage should also have an OPV if the shutoff is used to disable the only pressure relief path.
