Yoke connection hose with tire filler. Nice to have in the car or shop so you can use a scuba tank to fill your car tires.
*Safety note... you do NOT want to hook this up and just open the tank valve... you'll blow the hose. You need to hook it up, connect to tire and slowly crack the tank valve slightly. The valve will be needed to control how much gas is coming out of the tire filler fitting.
