Update: Enlarge hole in 70 yr old cinder block wall

atlarge54 · May 3, 2023

Thanks for all the tips. Here's how things went. While searching my toolbox for small masonry bits to enlarge the perimeter I found a couple mounted stones with 1/2" shank for a drill. They were 1.25" diameter with a nice conical point to guide into existing hole. Once I removed the existing tubing it only took a few minutes to enlarge the hole on each side of the block.

I found it interesting that the propane "professional(s)" that originally installed the regulator used pipe dope on the copper flare fitting.

Glad that it worked out for you.

I use a small amount of pipe dope on the threads of flare fittings. Acts as a never seize.

Sealant is also used / recommended on refrigerant flare fittings.

Propane pipe fittings are only supposed
to have pipe dope so I'm sure that is
what was on the truck.

I use pipe dope on pipe threads but not flare fittings. This regulator had dope on the flare fittings and the dope had squeezed into the gas path restricting flow and possibly causing debris in the system.
