Anyone have any experience installing Disco Boss valves into air tubes. My O-rings keep getting chewed up on the Fill adapter threads. I'm using #016 rings with the proper silicon lube. Tried both Duro 90 and Viton rings. I don't have a problem with the gauge port assy and that uses the same size O-ring. This is driving me nuts!
