Question Banjo fittings for DH.

[happy-diver]

These are brand new chrome plate

I would not imagine anything so primitive with oring face sealing in other indudustry

The standard banjos are far too broad with a chamber with metal washers for sealing
unlike the scuba hollow bolt you see sealed internally extra hose adapters with orings


"These are brand new chrome plated brass banjo fitting so you can use a SPG on your double hose. You must have a long yoke to use the banjo fitting. If you are not sure what style of yoke you have email me some photos and I can tell you. I also have a limited number of long yokes for sale for both two and single stages. Please check the site for availability. This banjo is 3/8 threads to work with your vintage pressure gauge. If you want to use a modern gauge using 7/16 an additional adapter is needed."

Is this different fittings, or both sides of the same

These are mine. One with the adaptor.
Both identical, just different sides.

Check with Rob at the Scuba Museum. He has had used, NOS, and new manufacture models.

Yes, I found one either on eBay or one of the vintage DH shops. Just so you know, I had to get a long yoke off a calypso 1st stage so I could get it to fit with my DH Mistral and vintage 72.

A word of warning - There are still some modern valves (pro-valves) that won't work...

 

[happy-diver]

Yeah I thought the longer recess was to clear the valve, with less to clear on the DH side

So a quick update. I put the banjo fitting on my vintage pressure gauge only yo realize that my banjo fitting wouldn't fit with the yolk on my Mistral regulator. After much hemming and hawing ( not really crazy that something I dive twice a year is such a PIA money pit). I realized I have a mid-sixties first stage with a longer yolk. After spending a bit of time trying to loosen a nut that hadn't been touch in fifty years, I swapped the yolks and put the new yolk on the DH and got the gauge on the tank and opened the valve.... Only to hear air escaping from the gauge hose (it didn't used to do that...)

Will a modern HP hose fit on a vintage Banjo fitting and gauge.

Yes, but you will need a 7/16"F to 3/8"M adaptofitting
