Product Information

The OMS Yoke AirStream 1st Stage conversion to DIN is a regulator accessory from OMS used to change an OMS AirStream first stage from a yoke (INT) tank connection to a DIN connection. It is cataloged under OMS Regulators and Accessories. Stocked under DiveCatalog item number OM50203; contact us to confirm the OMS factory part number.

Who it is for

This part is listed for divers who own an OMS AirStream first stage built with a yoke connection and who need to breathe from cylinders fitted with DIN valves. DIN connections thread into the cylinder valve rather than clamping over it, so the same first stage can be used on DIN-valved cylinders. It is also useful for dive shops, instructors and service technicians who maintain a mixed set of yoke and DIN cylinders and want their AirStream first stages matched to the valves they actually use.

Frequently Asked Questions

What does the OMS OM50203 conversion do?

It converts an OMS AirStream first stage from a yoke (INT) tank connection to a DIN connection. Yoke first stages clamp over the cylinder valve, while DIN first stages thread into it, so the conversion lets the same AirStream first stage be used on cylinders fitted with DIN valves. Stocked under DiveCatalog item number OM50203; contact us to confirm the OMS factory part number.

Will this fit any first stage, or only the OMS AirStream?

It is intended for the OMS AirStream first stage; contact us to confirm it fits your regulator before ordering. Before ordering, check that your first stage is an AirStream and that it currently uses a yoke (INT) connection. If you are not sure which OMS first stage you own, call DiveCatalog at 888-701-4017 or start a chat and we will help identify it.

Can I install the DIN conversion myself?

We recommend having the conversion done by a qualified regulator service technician. Changing the tank connection on a first stage means opening a high pressure assembly, so the finished regulator should be reassembled to specification, pressure tested and leak checked before it is dived.

Should I choose DIN or stay with yoke?

Choose based on your cylinder valves: DIN threads into the valve, yoke clamps over it. Converting lets one AirStream first stage serve DIN valves.
