I just bought a Falcon straight stem and a Billiard smooth bowl. The bowl came with a plastic (or rubber) gasket ring. The issue is that the bowl doesn't screw on to the stem well - it just slips and doesn't stay. If I remove the gasket ring, it screws on well, but I am thinking that there will be smoke leak which I could check by blowing air through the stem. I have never owned a Falcon before. Is this a common issue with Falcon pipes - becasue peiple must be purchasing stems and bowls from different sources? Is something wrong with the stem or the bowl? I will appreciate any insight.
