Best Fittings Extended Quick Coupler Socket 1/8" BSP Thread to Quick Connect

This item attaches to the end of your filling whip and gives you the ability to quickly swap between fill probes or attach direct to a foster fitting. 

This item is ideal for FX  Impact air gun owners as it allows for easier connecting/disconnecting from the foster fitting on the air rifle, which can be tricky if you use the one that comes with the air rifle.

This item comes with a 1/8th BSP thread at the rear.

This item should be compatible with most filling devices but please check before purchasing.

The decanting adapter is a male to male foster fitting which allows the connection of another Quick Connect Coupler

The BSA and Weihrauch/HW fill adapters connect straight into the coupler and into your rifle, no need to adapters.
