I have a exped pump bag for my Exped Synmat UL7 and I have a BA Q Core SL, I was trying to find a way to attach the pump bag to the big protruding valve. I tried a few things, tubing that fits the inner diameter of the pump bag flat valve and another tube that fits over that tube to attach to the big valve. At the end of the day, it was all too clunky, weighed too much and it was a big bulky thing that I'd have to carry.
Solution: I had left over polycryo (duck brand), double sided adhesive and some shock cord. I fashioned a tube out of the polycryo with shock cord at both ends. I cinch one side of the tube to the pump bag and cinch the other side to the BA Q Core valve and use the pump bag. It takes about three bag full to get the q core blown up and another two breaths to get it super firm. It's better than taking 20+ deep breaths to blow it up. Hoping that this will help someone else.
Take a look at the pics!
