It leaked air straight out of the box but managed to sort that just by adding a bit more ptfe tape and tweaked the rear nut where the adaptor sits. Placed back on the shelf for a fee days before needing it again and it decided that it was gonna leak again 🤦🏼♂️ Ended up stripping the entire tool down as far as I could go, reassembled............. and it still leaked. Chucked it in the bin and ordered a more expensive one. You buy cheap, you buy twice
