Oxygen Filler Hose

[FlyWalt]

Hello everyone,

I am setting up my own O2 filling system for my portable tank. Does anyone happen to have a source for a filler hose called a pigtail that’s connects from the larger tank to my portable? Or a source for it.

The local gas shop has a VERY high price on these items so I thought I’d check here first. 
 

Thank you in advance,

Walt

Tim Olson, a builder of an RV-10 and an RV-14, details his cascade filling system here:  https://www.myrv10.com/tips/accessories/oxygen/index.html

 

I just bought the parts he calls out from weldingsupply.com.  I had to get the pigtail hose from Amazon.  It's a simple system, requiring you to connect and disconnect from each cylinder in turn.  It would be simple to add a valved manifold to tie everything together, but for as often as you need to fill a tank, this is plenty easy.

You can get them on amazon or ebay for reasonable prices.   All kinds of adapters, transfill hoses, etc., are available as well.
