Sonar Dual Outlet Isolation Captured O-Ring Manifold (300 bar) -

Sonar Dual Outlet Isolation Captured O-Ring Manifold (300 bar) - Not Oxygen Clean. The Sonar Dual Outlet 300 Bar Isolation Captured O-Ring Manifold is designed and manufactured for long life and heavy use. It has a 215 mm (8.5 inch) centre to centre crossbar spacing that fits any diameter scuba cylinders using standard tank bands.

The manifold consists of left and right modular valves with an isolation crossbar. There are is a captured O-ring on each end of the isolation crossbar (similar to how the O-ring of a DIN regulator is captured by the DIN valve outlet).

You are ready to get a set of doubles and need a durable, high flow, convertible, isolation manifold. The new Sonar Dual Outlet 300 Bar Manifold with captured O-ring Isolation crossbar is the one you need. Sonar has always been known to make one of the most durable, high flow valves systems on the market and they have proven to do it again with this Isolation Manifold.

The modular barrel design connectors incorporate double O-ring seals known for their robust reliability. The valves come with standard 300-Bar DIN outlets and 3/4" NPS neck thread inlets that fit nearly all modern Australian standard scuba cylinders, like standard aluminium 80s, or LP or HP steel cylinders. The manifold is Nitrox ready up to 40% oxygen, bagged from the factory with EPDM O-rings for immediate use with enriched air equipment.

Precision machined from high-quality marine brass, the manifold will give years of service and corrosion-free operation.

The two valves have a standard 3/4" NPSM thread to fit most Australian Standard aluminium and steel tanks/cylinders/bottles. WARNING: Please ensure that you are fitting the valves to the correct cylinder. If in doubt please ask.

Manifold Oxygen Cleaning:

This valve is Nitrox ready up to 40%. If you are planning to use this manifold on cylinders with Enriched Air Nitrox (Nitrox) mixes from more than 40% up to 100% oxygen, it's essential for the safety of the twin-cylinder user, and the person filling the cylinders, that the manifold be oxygen cleaned and prepared with special O-rings, seats, and grease designed for exposure to pure oxygen. The cylinders should then be banded with the familiar yellow and green Nitrox band/wrap/sticker, and an Oxygen Clean 'In Test' inspection sticker applied. The Scuba Doctor can do all of this for you as an add-on service.

What is the difference between DIN "200 Bar" and DIN "300 Bar" valves?

The Deutsches Institut Für Normung (DIN) is a German standards-setting organization similar to our American National Standards Institute (ANSI) and Compressed Gas Association (CGA). DIN 477 is a specification that recommends cylinder valve outlet and connector designs for specific types of gases and pressures based upon safety considerations. These various designs have deliberate incompatibilities to preclude the possibility of errors when handling different types of compressed gases at differing working pressures.

The two valve outlets and connectors of interest for divers are the DIN 477 No. 13 and the DIN 477 No. 56 (formerly No. 50), both designated for use with compressed air. The DIN 477 valve and regulator fittings are most widely used outside the U.S. The regulator first stage DIN connector is a male screw type, and instead of clamping onto the outside of the valve as does the yoke, it screws directly into the female DIN outlet of the valve. The sealing O-ring is held at the end of the regulator connector rather than in the face of the outlet. The DIN 477 system, with its captured o-ring design, has proven to be very reliable for use with SCUBA.

Outlet/Connector #13 is from DIN 477 part 1 - for cylinders with test pressure ratings up to 300 bar and is commonly referred to in the SCUBA industry by the slang term "200 bar", probably because most cylinders with 300 bar test pressures have working pressures in the 200 bar range.

Outlet/Connector #56 is from DIN 477 part 5 - for cylinders with test pressure ratings up to 450 bar and is commonly referred to in the SCUBA industry by the slang term "300 bar". The two designs are nearly identical, but the #56 valve outlet is deliberately deeper so the shorter #13 connector will not be long enough to seat properly. This is a safety feature to prevent connecting a low-pressure device to a high-pressure supply.

It's important to understand that the "200 bar" or "300 bar" descriptions are just slang terms that have nothing to do with the pressure ratings of the outlets and connectors themselves!
