Why are these brass connectors binding up?
I have a M+F pair of connectors I want to use to make a ~air tight connection through a thick piece of rubber. Want to screw the parts together far enough that the hex-nut section of each part will act as a flange, and crimp the rubber in between.
However, I can not get the parts to thread together far enough. At about 1/2 the length of either, the connectors start binding up. I can only get the two about 1/4" away from being fully seated.
Are pipe connectors manufactured with a slight taper to create this? Or something else?
