WK fire extinguisher tanks (hoping to convert)

[1978davidw]

does anyone know of a place to purchase bushings for WK fire extinguisher tanks to convert them over to scuba? Im looking for the 1" NPT to 3/4 NPS or if absolutely necessary 1/2 NPT. i picked up 3 of these tanks for free and wanted to add them to my vintage diving equipment as these were commonly used in scuba.

HP bushing can be gotten from McMaster-Carr. You won't find any 1" taper pipe thread to 3/4" straight pipe thread, 1" to 1/2" taper pipe is your best bet.

Follow the Captian's advise

Bump bottom WK fire extinguisher tanks can be very (very) negative

Make certain the bushings are HP and not LP brass plumbing bushings.

You should be able to find those fittings in Ti if you want to save weight. A company like swagelok might carry them or if you have the money do custom fittings.

I second McMaster-Carr! I just ordered some this morning. McMaster-Carr

If you are interested in a couple of bushings with a pair of tanks, bands, and a harness attached let me know. They're the one's in the second pic in the following thread:

Anyone have a couple 1/2" valves they would like to part with?

How big are the tanks?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The second set of tanks in your picture are O2 bottles used in WW11 era air craft--they are very positive.

Fire extinguisher bottles are generally bump bottom and very negative- Almost too negative for comfortable diving..

Cut off the bottoms and they make great bells...our home and yard is full of SCUBA bells...
