This pump is absolutely outrageous. Have they given away for Christmas. The recipient is retired and does not look particularly good. That's why he wanted such a valve with locking lever (car valve), so he has both hands free for pumping. So I have spent much time later to get such an adapter or the like. Unfortunately none. The manufacturer offers something not on and the accessories I have found nothing. Unfortunately .... So back it. Would keep them happy. Absolutely high quality.
