Try seeing if the neck of a typical soda bottle fits, they're 28mm, you may have to file the threads off but worth a go....... the only trouble I'm having is finding an adaptor to fit on my schnozzel bag for fast inflation. internal dia is roughly 28mm
just tried and its too tight but thanks could still be on to something hereTry seeing if the neck of a typical soda bottle fits, they're 28mm, you may have to file the threads off but worth a go.
no, how do u mean?You tried the cork in the shopping bag way?
aye I have a similar set up for my xthermOk found a vid a few years with a guy using a cork and shopping bag. You snip the corner off a plastic bag and place a cork with a hole drilled in it half way through the hole and tie with a cable tie. You inflate the bag like a pump sack and press the cork into the mat valve and squeeze the bag
