My local BBQ person was unable to help tonight. Here's my problem: I have a new grill and am installing it in an island with NG piping (currently plugged). So I need to figure out what type of gas line (will any do?) to connect the grill to the T. Do I use 3/8" or 1/2"? Do I use pipe sealant or not?
Thank you!
Thank you!

it's a NG grill right ? not LP...
3/8 would be fine, use flare connections not compression. sealant is used on pipe threads but not the flared portion of the fittings. include a shut off valve in the installation that's easy to get to.

Yes - I am talking NG here. When would 1/2" be used instead of 3/8"? Tubing length is 5'. Can I go buy this length flex line at a hardware store and the appropriate connections (i.e., 1/2" to 3/8") and do it myself? Also, I'm glad you clarified when to use or not use the sealant. How do I know if a fitting is flared or not?
Also, the T does not have a shutoff. I'm assuming this is code, so should I install a shutoff between the T and tubing? I'll attach a picture as soon as I can link one.
Thank you!

Yes, you want to install a shutoff valve.
Personally, I'd use 1/2" pipe, although it's probably not necessary.
I'm presuming this is outdoors? I'd run 1/2" galvanized pipe to the back of the grill near the floor, then install the shutoff valve.
Use a flex connector to make the connection to the grill. Get a flex connector of suitable length and the compression fittings that fit the flex connector. You may need only a short flex connector since most gas grill make the gas connection at the base of the grill.
Use teflon tape or thread compound on all the screw fitting, but not on the compression fittings that go to the actual flex connector connections.
You don't want the gas pipe moving around, so you may need to use some plumbers tape screwed into a wall and going around the gas pipe to hold it securely in place.
Turn your new gas shutoff valve off and turn on the gas supply. Soap out the fittings with a solution of dishwashing detergent and water ---- use about 1:4 detergent to water. Use a spray bottle or a paint brush to soap out the fittings.
After you light off the grill, soap out the fittings downstream of your new shutoff valve.
