Gas Grill line: Frozen connectors - loosening techniques?

zarkbuilder

I have to replace an outdoor flexible NG line that connects the grill to the NG supply metal pipe. Metal pipe/Gas grill line connection is a quick-disconnect - no problem. done.

Inside the grill, the flexible gas line is screwed to the grill (regulator?) with 2 separate nuts. One of these seems to be an adapter. With the cold weather, neither nut will move. NO GAS. Grill line is disconnected from supply. So, its safe for heat.

How to loosen frozen nuts? (yeah, I cant make any jokes here…….)

Heating the nuts slowly? Will WD40 (et al) work below freezing temp? rubber mallet? or do I bribe my nephew who lifts weights every other day at The Gym, but can't "carry" a conversation unless he saw it on Snap Tok? ;-))

The connection at the regulator is reverse (left handed) thread. Now you might need your nephew because you made it super tight. Don't forget to use a counter wrench on the regulator.

THANK YOU! Yes, it was reverse thread. compensated nephew with several well-grilled burgers. win-win. I attached a new longer flexible gas line that allowed greater movement away from wind. Is there any DIY test/check I can do at the gas shut off valve due to age? It is 4 seasons exposed and I place an open bucket on it in the winter. Thank you again.

I have several NG quick disconnect connections and never do anything with them in the winter, other than use the appliances. If your valve is only 4 years old I wouldn't expect it to have any issues.

For what it's worth, some areas require a tether to the grill to keep it from pulling on the hose no matter what happens.
