Fast, Fuss-Free PCP Filling

The Best Fittings Quick Coupler Socket takes the hassle out of charging pre-charged air rifles. Instead of unscrewing and rethreading adaptors every time you fill a different gun, you simply snap probes in and out, saving time and protecting delicate threads.

Standard Fit, Wide Compatibility

Built around the industry standard 1/8 inch BSP thread, the socket works with fill probes and hoses that share the same fitting, and is compatible with Foster 12FS, 12FSS and 12MS straight-thru quick snap couplers used across the airgun world.

Rated for Real PCP Pressures

The socket is safe for use on pre-charged equipment up to and including 300 BAR, or 4500 psi, so it comfortably handles the pressures of modern PCP rifles, buddy bottles and pumps.

Ideal for Multi-Rifle Shooters

If you run more than one PCP, a quick coupler socket lets you move between them in seconds with the right probe for each. Browse more outdoor shooting and PCP filling gear.

Frequently asked questions

What does a quick coupler socket do?

It lets you switch between different fill probes in seconds by snapping them in and out, rather than unscrewing and rethreading adaptors each time you fill a different rifle.

Will it fit my fill hose?

It uses the industry standard 1/8 inch BSP thread, so it connects to hoses and probes with a matching 1/8 inch BSP fitting. It is compatible with Foster 12FS, 12FSS and 12MS couplers.

What pressure is it rated to?

It is safe for use on pre-charged equipment up to and including 300 BAR, which is 4500 psi, covering the vast majority of PCP air rifles and bottles.

Is it worth it if I only have one rifle?

It still speeds up connecting and disconnecting your fill line, but the biggest benefit comes if you own several PCPs with different probes, letting you swap between them quickly.

Do I need matching plugs?

Yes. Each fill probe or adaptor needs a matching quick coupler plug to snap into the socket. Best Fittings starter kits typically include plugs and seals to get you going.
