Use this spin-on adapter to connect any 200 Bar or 300 Bar DIN first stage regulator fitting to a yoke-type cylinder K-valve. The DIN-to-yoke spin-on adapter is marked with a 3500 psi / 232-Bar rating and features a nice sized easy-grip handwheel which makes it easy to mount and remove.

Over-Pressure Relief Valve (140 psi service)

To provide better drysuit insulation than their back gas breathing mixture would, divers sometimes carry a small pony containing argon or air with just a first stage regulator and a low pressure drysuit inflator hose. However, on dedicated drysuit inflation systems there is no regulator second stage to provide relief should the high pressure seat fail. Without a way to relieve the pressure, the drysuit could begin inflating rapidly or the low pressure hose could rupture. The over-pressure relief valve provides the same fail-safe function as a normal regulator second stage.

The over-pressure relief valve screws into any available first stage low pressure port and is set to 220 psi for 140 psi service typical of the IP in most regulators (may be adjusted in the field to any value the user prefers). Note: the OPV is included with the Dive Rite drysuit inflation regulator. Also available in a version set for 90 psi service with the oxygen first stages found on rebreathers.

Octo Holder for 2nd Stage

Ideally, alternate air source (octopus) second stages are where you stowed them when you reach for them and are not dragging along the bottom. The simple, rugged, and reliable Dive Rite Octopus Holder keeps regulator second stages securely in place when not needed, yet releases them quickly in response to a firm tug.

• The elastic shock band that encircles the second stage mouthpiece does a great job of holding on to the second stage, yet will release it quickly when tugged.
• The Dive Rite Octopus Retainer fits a wider variety of second stage mouthpieces than the plastic dip-molded type. You don't have to fight to get a mouthpiece inside a Dive Rite octopus retainer - only to see it mysteriously fall out later.
• The low-profile, sliding-bolt snap helps keep overall "dangle" to a minimum. It enables you to move your extra second stage quickly from one accessory D-ring to another (something many divers do when suiting up or removing equipment). It also makes the octopus holder perfect for taming wild decompression or stage regulators.

Hose Clip Retainer (Package of Two)

The Dive Rite Hose Clip Retainer is a simple device that replaces the need for cable ties, o-rings or cave line to attach clips to regulator and SPG hoses. Simply pass the bungee through the clip opening, around the hose, and over the tab. This connection is secure but can still be easily removed for reconfiguring. Sold as package of two hose clip retainers.

Dive Rite Necklace, 2nd Stage Regulator

The regulator necklace is an increasingly popular method to manage your alternate air source. The necklace concept derives from technical divers that had a need to keep their back-up regulator close to their mouth for instant availability. The Dive Rite Regulator Necklace is made from standard 3/16-inch bungee and is fully adjustable. The necklace is perfectly designed to fit around a diver's neck, with or without a hood, keeping your auxiliary air source close. The adjustability feature offers a significant improvement over the one piece molded silicone versions that are rarely perfect fit and almost twice as thick.

2nd Stage Pocket

The Dive Rite 2nd Stage Pocket can be used to protect the regulator of a staged cylinder. It can also be used as a shield to help avoid accidental deployment of a decompression regulator below its safe Maximum Operating Depth (MOD). To use, detach the second stage and route the LP hose through the slot in the bottom of the pocket. To deploy, pull the second stage out of the pocket, allowing the hose to slide through and leaving the pocket attached to the cylinder.

The pocket flap uses a velco closure and has a 1-inch stainless steel D-ring on the back that can be attached to cylinder stage strap neck clip using a double-ended snap or a quick link. If you prefer, it can also be mounted in a variety of positions by adding a tank strap, and using the 2nd stage pocket's unique H pattern belt loops on the back.

Intermediate Pressure (IP) Check Gauge

Most regulators, including those from Dive Rite, should have an intermediate pressure of about 140 psig. When diagnosing regulator problems, it's often very helpful to know if the IP is out-of-range. Slightly out-of-range values typically indicate the need for a simple IP adjustment to compensate for wear. Significantly out-of-range values, particularly with "creep," often indicate a more serious impending high-pressure seat failure. In addition, slow recovery time can indicate a clogged inlet filter.

The compact 1.5-inch diameter ultra-lightweight dual-scale (PSI and BAR) intermediate pressure gauge is ready to go with you anywhere. Perfect for helping diagnose problems in the field, it plugs into any standard BC low pressure inflator hose.

Deluxe Intermediate Pressure Gauge

Quickly check and adjust regulator intermediate pressures by plugging the Deluxe IP Gauge into the low pressure QD BC hose. The gauge makes precise IP adjustment faster with an easy-to-use bleed (twist in either direction) that gives a quick vent and an over-pressure relief valve set at 200 psi. The large 2-inch diameter gauge has a protective rubber boot and dual scales (PSI and BAR), with an accuracy of 1.5% throughout the entire range.
