Which LP valve adapter do I need

KRum · April 24, 2016

I am installing a catalytic heater in my RV and the hose/regulator that came with the heater (top in pic) and the extend a stay valve (bottom in pic) do not match...

Is there an adapter I can get to link the two?.... I found this one on Amazon that might work but not sure?...

Not sure how the valve works but the threads on the right side of the valve look like they match the hose connector. Can the valve be turned? Considering the same type of heater so curious how this works out for you.

^^^ Yes the threads on the right would fit the heater hose connector but I can't use that one because it will already be in use to pass thru to the existing regulator.... See here... My assumption is I need the use the

"Grill Tee" to connect the heater

The system, connector and regulator, on top of the picture is designed to go from a tank (high pressure) to the heater (low pressure). If the regulator/connector is replaced with a line that connects directly to the low pressure system in the RV it would work.

if you know how to do that correctly, great, if not have a propane or RV shop do it for you. Normally a low pressure disconnect is used and that allows the heater to be put away during the warmer months.

There are several "how-tos" on the web showing how this is done.

on edit: This is one of the ways to do the mod. : http://www.loveyourrv.com/mr-heater-big-buddy-hooked-to-my-rvs-lp-gas/

Thanks Mike... I agree and understand your concept but I don't want to make such a perm & expensive connection... I want to have the option of removing the heater hose/regulator and attaching a grill and gas fire pit too...

I have already bought these connectors - where I have them aligned in my pic is where they could in theory connect if I have the right adapter to fit them together ;-)

yes. the end of the hose you picture is the end that goes to the bottle. on the valve, the top is the thread found on the 1 pound bottles. on the valve the one to the right is the thread found on 20 pound bottles. The one with a blue cap, i can't tell, but looks like the old internal thread on the 20 pound bottles. I am not sure this is the valve you need.

If you installed the extend a stay , then you could easily and very inexpensively accomplish what Mike described .

From the yellow handled ball valve to the gas pipe is what you'd need , along with what ever hose to connect your heater .

Or , using what you already have , the black hand nut portion of the regulator would be replaced with a nipple that would screw into the thread adapter of the tank tee .
