Propane Line capping?

Hi. I recently bought a used truck camper. It had a fridge and a stove. The fridge did not work, but as far as I can tell, the stove does. I removed the fridge, but now I have an open propane line. I know I can just run a single line now and that's the ultimate goal.

But in the mean time, can I use a ball valve water line shut off to cap the old line to the old fridge?
By cutting the nut part off and putting the ball valve fitting on the end. Which would in theory work. My thought is, if the ball valve can stop water, would it stop propane?
  • Valve by itself is not legal... it still needs a plug installed.

    Standard fitting hardware will have the plug you need. Any hardware. IF you still have it take the solenoid valve from the fridge. Else measure the nut's opening

    This is the easiest/cheapest and BEST way to cap off a LP line. Doug

    PS, BRASS, not copper:B
  • Yup, looks like this. It’s in the plumbing section with all the other brass fittings.

  • I would use a proper gas fitting that caps the existing threaded end fitting.
    Or if needed attach the proper compression fitting to attach the cap.

    I would not attach a valve. Especially one made for water.
  • LPG **** valves are affordable and proven. They usually have a twist dial-like wheel on the side. Is a trip to the hardware store a burden?
