Bought this for my portableWeber 386002 Q 100 Portable Propane Gas Grill; works perfectly with 20lb propane tanks.Works like a charm, but CAUTION: If you plan on disconnecting the 20lb tank with the hose, you may receive some propane blow off. THIS IS OK! It is just the build up within the 5 foot hose.HOW TO RESOLVE THIS ISSUE:Towards (or at) the end of cooking, close the propane nossel to off while keeping the grill turned on high. This will burn off all the leftover propane in the line. I usually turn it off within 3 minutes left of cooking as to not waste it; sometimes it'll continue burning, slower and slower, for 5 minutes after.
