I'm installing a new water heater and need to install a gas shutoff valve (with flare end) connected to flexible gas line. The flex line instructions say: Do not use Teflon ® tape or pipe sealant on any flare ends because you will not obtain a leak-free seal. Keep flare end of fitting free of grease, oil and thread sealant. I just want to double check that means no dope on the flare end threads too, not just the flare itself, correct? And I assume that's because the flex tube is compressed to the valve flare for a tight seal - no need for thread sealant. Attached Images   Last edited by diggerdave; 02-09-2009 at 10:33 PM.
