Home Forums Hunting & Shooting Hunter's Campfire LP Gas line, need help

I need to run a new flex line from out of the wall to my new stove. Coming out of the wall is a 1/2 male connector, but per mfg. suggestion the flex hose should be 3/4. So I got a 1/2 to 3/4 expander but my question is can I use the basic expander below with the "beveled" nose of the 1/2" male connector? Gas is LP if it matters.

the bevaled male is made to seat against a fitting. personally I don't like it, and think you should put in a wood stove

This is for my range (stove) already got a wood burning insert.

Seriously though, can it work? I realize it's meant to sit against a fitting, but they don't make them from 1/2 to 3/4 and I'd rather not replace what's on the wall.

if the thread pitch is correct, snug it up and use a soapy water solution to check for bubbles, a match will work but i wouldn't recommend it. but seriously i would check with soap. and i don't think it will work being a taperd end but i just don't know I have never messed with gas supply
However you are alreay reduced to 1/2 supply line so i don't understand increasing the size back up to 3/4 you won't gain much if anything in volume, but i guess it would reduce pressure

NO! You are attempting to make a connection with incompatible fittings on a flammable fuel supply. Don't do it.

What you picture is a flare fitting type appliance connector with a running thread and a black iron (or malleable, if you prefer to call it that) reducing coupling. The black reducing coupling uses a tapered thread that, along with thread sealant, makes a gas tight connection. Take the time to get the right fittings and make a proper and safe connection.

That's a no fly. You need pipe thread to pipe thread in order to seal. I believe you have a flare there.

I believe the reason they are telling you to go 3/4" on your flexible connector is because the corrugations of the flex line are restrictive to the flow of fuel.

I'm curious, how many BTU's is the appliance you are trying to connect?

Listen to Bruinruin, Flare fittings have NO taper in them and will not seal correctly. yes you may wrap enough teflon tape around it to give a temporary seal but it WILL eventually begin to leak. Common and dangerous mistake.

JR, I sent you a PM.

You need a 1/2 male flare x 1/2 male pipe thread with into your 1/2 x 3/4 female pipe union. Then use a 1/2 x 12 flare swivel [looks like 2 flare nuts on short piece of copper tubing] to tie it together. Only tape tapered pipe thread and not flare fittings.

I even hate flex... Let alone cobbling together fittings that do not even speak the same language...

all gas fittings should be tested to 100 psi ,what you have is an accident waiting to happen and take your house with it ,listen to a quilified gas fitter

Sounds like the black pipe is my problem.

Would this be a better solution:
Go from my 1/2" flare to a 1/2" female flare swivel



Then get another flare that goes from 1/2" to 3/4" which will connect to 3/4" flex tube.

if your 3/4 flex tube has a female 3/4 pipe thread that should work,
i am not a quified fitter i have just done my own log house with LP gas with a qua fitter as backup,
remember LP gas runs at very low pressure but if tested to 100 psi should NEVER leak

"All gas fittings should be tested at 100 psi' is BS!!! Propane gas check is 10" water column for 10 min. Reason is 100 psi would blow the gas valves right off your range and destroy each gas control on each appliance. I am 1 of those "quilified gas fitters' or AS we like to refer to ourselves as 'certified'. The OP is working with an APPLIANCE connector which calls for 10" water column test [approx 6-7 psi]. Basic plumbing of house before appliance installation in construction can require higher psi testing if local building inspector requires it. When propane tanks are set at residence 10" WC @ 10min meets requirements.

yup but i tested befor hooking up to abunch of lights and fridge abd stove ,,your clarification is much appreciated and that is why i said a quified[certified ] fitter ,i left out an important part ,,
thank you for clarifing ,
norm

This is the kind of stuff that gives me nightmares! I corrected this very mistake on a range not very long ago. How the man of the house had NOT burned the house down and killed him, his wife, and their toddler with the resulting leak, I will never know. If you don't know a bell reducer from a half union, then PLEASE get a professional!

jr,
I work with gas also.
If you'd like to talk directly, you have my number.
