Hello folks, it seems I only offer these around Christmas time & I have a few to sell if your interested, I have probably made over 50 of theses now & they are used for Jensen steam engines only with the 5/16-24 thread (most Jensen's) you simply remove the whistle & you can either use these to fire another engine from your boiler....or you can use to run your engine off of compressed air with a good quality silicone hose, I'll include (2) Teflon gaskets to help get the proper orientation, they're a handy little throttling valve that has precision adjustment.
I have 10 of the unplated brass body valves with either black or red handle (makes no difference to me ) and 2 that have been professionally nickel plated with either black or red handles, when these are gone ….they're gone, Unfortunately I don't have time to make anymore right now. these are my best yet, the nipple is all one piece brass turned down & tapered to 3/16"
brass body valve $44.00 inc shipping in the US
professionally Nickel plated valve $54.00 inc shipping in US
Just PM me if interested. payment by either PayPal (friends & family) check , or cash (they still make that ?)
a simple video of its use...
