Aftermarket replacement complete male fill valve for the Benjamin Kratos air rifle.
Common source of leaking this spare replaces the complete unit on the rifle and is already assembled.

Complete unit with internals already installed.

Converts it to a standard Forster fitting – an improvement on the original filling adaptor (which will not work with this). If you do not already have one of these they can be purchased here,  we also stock a suitable dust plug cover here.
