How did J and K valves get their name?

[Ber Rabbit]

I read, on the board I believe, that the names came from their identifying letters in the Sears/Roebuck catalog. Does anyone know if there is merit to this? If there is does anyone have a catalog with the valves in them? I would like a copy (photocopy is fine) to put into my OW lectures.
Thanks!

I heard it was from a catalog but I don't know if it was a sears catalog. I can't help you with the copy though cuz the only copy of the sears catalog we have is out back in the outhouse.

They were named after the inventors: Jay Cousteu and Kay Ballard.

OK, I lie.

Hey Mike, if that catalog's been in the outhouse that long please tell me it wasn't put there to satisfy sanitary purposes :klo:

That catalog has been "Red Flagged" and cannot be distributed!!!!

I was told once that the J valve was becuase on the old equipment of the wire than ran down the BC (with the loop on the end ) looked like a "J".

And the newer K valves had a "K" look to them.

Of course this could have been some ego driven dive shop owner
who just enjoyed hearing himself talk and make his students think that.


A google search found a posting on another board that suggested
it was a ScubaPro catalog code designation for J valve and the next
valve was K because it was next in alaphbet. Don't know how a "H" valve
fits into this order though

It was the 1953 Aqualung catalog. I don't have that, but I do have a copy of the 1955 catalog. I'll drop a photo copy in the mail on Monday. Look on page 7. The k valve is $7.95, the J is $30.00.

There were no BCs then.

The old AT Packs or water gills harness had a horseshoe bladder around it
that I would consider a BC.... they connected to the harness with
steel rings around the tanks (steel 72's) and had the J valve with
the long wire to switch to reserve at around 500psi.
