Oxygen system in ASW-27 ASG-29

Recently acquired an ASG-29 (ASW-27-18)and unable to mount O2 regulator on bottle behind seat back. Not enough room with seat back in aft position. How have other 27/29 owners solved this problem? Flex high pressure line? If so, where was it purchased?

Thanks

Mine fits great right on the bottle. MH system. In both a 27 and a 29. Do you have the right bottle?

I just posted what you may be looking for on the Yahoo ASW27 newsgroup, including a photo.

We do have the correct O2 bottle. Did not want to cut seat back.

I am a dealer for Mountain High Equipment and have installed several ASW-27 systems. Contact me at: info (at) mmfabrication )dot) com if you don't get the information you need from RAS.

The ASW-27/29 will only accept a steel cylinder of a particular size, and the regulator mounts at a 90 degree angle to the cylinder. It usually has sufficient clearance to the seatback (if the regulator is angled slightly outboard). The interference is usually the large cast aluminum handle that opens the valve on the cylinder. Either remove the retaining screw on the handle and only use it to open and close the cylinder valve before and after flight (use a string to keep it attached so you don't lose it) or make a simple one-wing handle that will not interfere with the seat back. If you need a handle and don't want to make one yourself, contact me.

What is your serial number? I have 29004. It has a euro bottle size and I still have not been able to get one that fits (from all the usual suspects). I have to use a small Mountain High Bottle and fill every day. Ugg.

Serial number 29055

Handle removed, but not enough clearance with seat back in aft position. Tried all orientations for regulator/bottle

Stupid Question - Is the bottle all the way
in?

There's a housing to hold the bottom of
the bottle, but the bottom tends to miss
leaving the bottle a couple inches farther
out than it should be.

Contact John Murray at Eastern Sailplane. As the former Schleicher dealer for many years he has both the experience and the O2 bottles to help you. Take a D steel cylinder, but not every D cylinder will work. John measures the cylinders and keeps the ones that work. MH has a Kevlar cylinder Which is smaller than the allotted space, which will work when wrapped with foam or vacuumed packed survival kit and is much lighter than the steel, but a bit small for western flying.
