    Various adapter models are required to fill gas cylinders with differing cylinder valves. The TK350-TN350 quick release system by WEH® ensures quick and easy WEH adapter changes. The bayonet lock releases the first adapter immediately and connects to the next adapter just as quickly. You save time and money. The 360° TD1 swivel joint is a perfect choice for moving a depressurised WEH® adapter into the perfect connection position. The swivel joint also prevents the filling hose from twisting.
