Air Arms Quick Fill Conversion Kit for S3/4/500/*10 EV2 & ProTarget

Upgrade your standard Air Arms cylinder fill port to a Gauge and Quickfill unit, allowing for a front-mounted gauge allowing a fill reading once regulated. The built-in gauge and rotating collar ensure convenience and protection against dust and dirt. 

The kit includes the fill probe, featuring a 1/8" BSP thread for easy connection to your dive bottle or compressor whip. The quick fill unit securely tightens once the air cylinder is filled, eliminating the need for excessive tightening.

If you are using a quick connector coupler on your filling device, we also supply fill probes that plug straight in to these. To view them please see our other items.
