Hmmmmm. So I've noticed this in the past, but recently was the first time it became an actual issue. I could not insert it into the fill line due to the burr that had been raised. Presumably this is caused by the ball detents pushing on the collar when pressure is applied over and over again. They dig into the material and push it back little by little.
The foster fitting in the pic is brass, but I've even noticed the same phenomenon on stainless steel fittings, but to a lesser extent.
Either way, guess I'm done buying brass foster fittings.
