I BOUGHT THIS TO REPLACE AN OLD ADAPTER I HAVE. THE QUALITY HAS DECREASED. THIS MATERIAL IS NOT AS THICK AS THE OLD TYPE AND HAS A PLAIN O-RING FOR THE ADAPTER INSTEAD OF THE OLD CAP RIMED STYLE. DURING INSTALLATION THE SCREWS ARE PUSHED THROUGH THE PLATE DUE TO THE THINNESS OF THE MATERIAL. NO NEED TO SAY THIS LEAK IS VERY BAD AND I NEED TO REUSE MY OLD ONE.
