The Mountain High Cylinder Neck Extender is used in applications where clamping at the cylinder neck is desirable.
It attaches between the bottle and the valve.

There are times when there is not enough area at the cylinder neck to allow clamping.
Our Cylinder Neck Extender extends the area between the cylinder neck and the valve allowing clamping in this area.
This is used mostly to fit AL- cylinders in Schempp-Hirth gliders.

Includes a filtered pass-through port and all required o-rings for sealing.
Cleaned for Oxygen service.
