You mean to connect the fill probe to your hand pump?One of these badboys should do the trick:https://www.pyramydair.com/product/air-venturi-male-quick-disconnect-1-8-bspp-female-threads-steel-rated?a=3550The EDgun probe comes with the 1/8" threads. I dont know why they don't just start making all the probes one piece with a male foster. Or just make everything quick disconnect!
Most manufacturers use a probe fill system, it's only the americans that use fosters,.....maybe they should change to probes
The reason they don't use one piece probes is that a large part of the world screws the 1/8 BSPP 8mm fill probe into their micro whip hose. I send the guns out with an adaptor. Personally I like fill probes, keeps the gun looking clean, Edgun probes fit many other brands
