I've searched and the only air gap that's not made of plastic I could find is this copper one but it still uses a nylon nut. It seems all of the air gaps I've used or seen, the nut will strip out when tightening, bumping or installing hoses. (I do install hoses before installing air gap.) Have any of you plumbers used this one or know of a high quality air gap that doesn't use a nylon nut?
