Foster male-to-G1/8 BSP male adapter with valve

Foster male, stainless steel adaptor to G1/8 BSP male treads, with o-ring valve.

This robust quality foster male quick connect adapter, is made of thick wall, solid stainless steel and has male G1/8BSP treads.

The o-ring powered valve can be set up for slow and fast filling and by setting the preload loose or thighter; it is perfect for tethered shooting on an external regulator because there is no spring power of the fill valve to overcome. Not to be compared with the cheap china stuff! It can be used with an o-ring (provided) under the collar of the adapter to seal or you can use it with an bonded seal.
