Dually valve extension issue, question

When I buy the flexable extension kits they come with long and short ones in the kit. I usually buy 2 kits so that I can use the long ones for both the inner and outer tires. I use large hose clamps to go around the center cone of the wheel or liner and mount the small L shaped bracket to hold the end of the hoses. Ialso install these with a small set of channel locks because if you don't the O ring inside will not get squised enough for a good seal.
Just my .03 (inflation)
