I have several vintage tank valve styles available.  I am always getting new and different stuff in so please check back or ask.  Shipping to USA for one valve is $5.50.  Shipping for 2 up to about 6 valves will be $10.50.  I cannot certify any of these valves for diving and even if they are NOS I must insist they be rebuilt prior to use.

I have a lot of US DIVERS K and J valves in stock.  They are 25.00 each in good condition.  I have some in lesser condition that can be had for 15.00 each (not pictured).

I have several VOIT J valves to choose from.  The top three pictured are $30.00 each and the rough ones are $10.00 each.  Or $100.00 plus shipping will take all 5 if they are still available.

This Seamco J valve is NOS.  It has some shelf dust but it is brand new and never in the water.  The first $40.00 plus shipping takes this rare one.
