Review on REGNHLIF Compressor Female Thread Fitting by Bradley Wacks

I used this on a short section of overhead power line but I had a leak. After spraying with soapy water I found a leak at the joint on the inside where this valve was. I tried to tighten the connection and the whole valve broke in 2 pieces (the female end came apart). I suspect there must have been a crack in the part that caused the leak. Maybe I overtightened it, but that's never happened to me.
