A detailed question about closing off a gas stove connection?

Question

My grandfather put in this hook-up when my parents built their house, in case we wanted to add an extra stove. We have an electric stove there now and want to close off the line for safety reasons. Here is a photo of the pipe. We want to put a nut on the end, but I'm pretty sure there aren't fittings that match with the hose hook-up. We're trying to get the end of the pipe off to get to a standard thread. The thing won't budge. Any suggestions (reverse thread, etc.)?

Answer 1

You may need to use two pipe wrenches.   They are right-hand threads for sure (I can see that as well in the image), so be sure you turn the pipe to the left as viewed from the end of the pipe (i.e. looking up).    You can then put a plug into the end of the valve - be sure to use pipe thread sealing compound on it.

Answer 2

use two bigger wrenches (brass if possible) leverage is your friend.  non-sparking metal tools is your angel.

you will need thick tephlon tape or dope made specifically for gas lines on the thread for the cap.

better yet, let me sleep at night... have a licensed plumber do this.

Answer 3

If this pipe is as it appears to be, tight against a cement block wall, then you may have to remove it from the feed line farther up near the ceiling where you may be better able to get a wrench on the pipe.  It would appear, the way it looks in the picture that you wouldn't be able to get a pipe wrench completely on the pipe itself.   If that 's the case, it's going to be next to impossible to get it apart without going  higher up.   If you have to do that, just be sure to turn off the main valve outside, if there's no way to shut it off inside.  Once you get it loose, as a couple of the other folks have said, just get a plug to put inside female threads, or a cap to put over male threads, whichever winds up on the end.   You can take the valve right out of the line if you have to.   All pipe threads are right handed threads.  Righty tighty, lefty, loosey.  You can check the plug or cap with a little soapy, sudsey water.

iit looks like you have a standard gas shut off with a short nipple attached the piece at the end is the compression fitting for the gas flex line get two strong people two good size pipe wrenches and try to un s***w the compresson fitting first if that dosnj't work grab hold of the bottom of the gas vaalve and unscrew the nipple if you get the compression fitting off get a cap of the same size and s***w it on ,if you get the nipple off get a plug of the same size and s***w it in ,in either case make sure to use pipe dope on the threads so there are no leaks
