Tips for replacing a tank valve: Looking at the valve from the top, righty tighty, lefty loosey A torch can be used to loosen Lotctite Clamp the bottle near the top or bottom where you will less likely to distort the bottle Make sure the tank is empty Use a smooth jaw vise so you do not scratch the tank An old leather belt makes a nice clamp pad Use red Loctite when replacing the valve The replacement valve will have a small hole in the threaded area. This is to vent pressure in the event the valve is pulled when pressurized. Avoid getting Loctite in this hole.
Thanks Steve, I will throw my 2 opinions on some items, I am not a fan of using Red Thread lock on the valves as it make future servicing harder to do Blue (medium) is more than ample when considering to will put the valve back in and snug it down. Also using a torch only just enough to apply a light heat. Aluminum can change its chemical treatments and temper. Note aluminum gets softer the hotter it gets. Of course your not trying to make it glow. So don't heat to the point paint is starting to bubble. Keep the flame moving
