This SAA 1/8 BSP Long Reach Adaptor is also known as an extended quick Disconnect 1/8 BSP adaptor. Designed to easily fill airguns with hard to reach fill ports, like those on the FX Impact and FX Crown. And also most air rifles with the fill nipple sunk into the rifle stock. You get a nice grip on the textured sleeve, making connecting and disconnecting a breeze.
The adaptor features 1/8 BSP male threads, with a release collar close to 30.5mm long. When you have a fill station that uses a quick connect coupler, you need this long reach adaptor to connect to it safely and securely. If this coupler does not fit, you won't be able to fill your rifle at all. Most fill stations require a 1/8" Female Standard Male Nipple to be added to this coupler to connect to it.
The 1/8" Female Standard Male Nipple is one of the most used filling parts. It's also known as a ST-N1 Microbore female nipple 1/8" bst. Very handy when filling various brands of PCP air rifles, as it works in union with the micro coupler.
