Anyone converted any of the Crosman bulk fed guns (111 through 116) to use the male one way Foster nipples?
Crosman 11x converted to Foster

- Start date
I would check with Baker Airguns or Mac1 as they seem to have lots of adapters for the older guns.

The crosman bulk guns thread is 1/8” ip straight thread...it’s a shallow thread and seals on the gasket at the bottom of the thread..screwing in a foster with a tapered thread might not engage enough to hold securely...

BSPP thread Foster male will work very well iiid you remove the Filling Head Spring Washer so that the Foster fitting sits flush on the sealing washer. The check valve in the Filling Head does the sealing . I also works well if you use the Filling Head without it's parts inside and use a BSPP Foster with a check valve. I either case, only need to screw in the Foster tight by hand and then a slight tighten with a wrench. Just leave the Foster in place all the time with a cap on it to keep out dirt.
