Have a look through this thread

Thanks. The "plumber" at HD tried a 1/8" fitting but couldn't get it to thread into the back of the coleman fitting more than 1 turn. Can't remember if the spring was still inside or not. I think I'll buy a 1/8" to 1/4" NPT fitting and see if I can gently get them to mate. I just hope he didn't cross thread them...

Hi Mister,
I went to a private store that sells and installs propane appliances, fireplaces, etc I went through their fittings bin and found a nipple that worked, I believe it is 1/8" NPT nipple.

Here is my thread from a few years ago -
I ordered several model 250 propane quick connects that fit my Crusader, had the local propane place make me a 20ft hose with the quick connects on it. I then went to the hardware store and bought a 3/8 female flare to 3/8 female pipe thread adapter. this adapter threaded right onto the propane inlet on the grill! Worked great and only cost about $1.50 not including the longer hose, works fine with the short hose, too. The OEM connector had a needle that depressed a recessed Schrader valve on the regulator end allowing propane flow only when fully engaged. the flare adapter threaded right over the needle so no cutting or anything just a wrench and some thread tape.

If you refer back to page 4 and look at the pictures I posted, I'll go thru the assembly of what I have.

There are no universal part numbers for the fittings, but I'll go over what they all are...

First off, everything is 1/4" inside diameter.

The hose I use was cut to length at 10'.

Starting with the male/female quick connect fittings end of the hose, they are standard fittings and can be bought at a RV dealership or online. The ones from the propane shop had a different inside diameter on the male end and would not work with the female end on the trailer.

The T-valve is a 1/4". The male quick connect threads right into this. The female end is connect to the t-valve with a 1/4" nipple.

The t-valve is connected to the hose with another 1/4" nipple and a 1/4" hose barb. Then you have the hose itself, and on the other end is another 1/4" hose barb. Into this hose barb you thread a 1/4" male pipe. Then comes a 3/8" OD 1/4" ID elbow. Then you have a 1/8" male pipe x 1/4" male pipe reduced. Into the 1/8" end is the regulator assembly (minus the regulator) from Coleman.

Hope this helps. I tried to go from one end of the hose to the other and hope I didn't get too confusing along the way.

Dave.

Locally I couldn't find a 1/8" male to 1/4" anything so I had to buy a 1/8" male to male nipple, a 1/8" female to 1/4" female and I added 1/4" 90. I ordered a Camco 59903 quick connect to 1/4" male but I'm not 100% sure this is the correct fitting for my application. If that works I'll order a 10' Camco quick connect hose to give myself a bit of reach and flexibility.

But... And I can't believe I did this. I was trying to put the spring back in the Colman adaptor for that small valve inside and BOING! It went flying inside my truck... So until I manage to find that from whatever crevis it's hiding in, I'm on hold...

If you use the 3/8 female flare to 3/8 female pipe you don't need any part of the regulator. You just slip the female flare over the male end of the grill and it threads right on. Then your male quick connect threads onto the 3/8 NPT.

I would not worry about the continous flow valve. I took mine out and threw it away, it is required when using the little bottles as they don't have a shut off on them and if you disconnect the fitting from the grill they will just flow till empty. With the roadtrip you have the control valves that shut the gas off in the grill and the main shutoff on the QD hose. I always shut off the hose when the grill is not in use so I figured why have that silly little valve in the line.

[Mister]

Thanks for all the help. I managed to get the parts together. I'm still waiting on the 1/4" npt quick connect. After that I can test it on the rig.

[Mister]

I finally got all the parts together. Thanks to all of you that helped me. I haven't tested this yet but I'll update when I do. The image below hopefully will help any future builders of this adaptor.

[Mister]

Here's the finished product. As a few others have mentioned the maximum output seems reduced a bit. However the grill still heats to 600 degrees in under 10 mins on high so I really have no complaints. Thanks for all the advice.

Is the Coleman brass connector a proprietary fitting, I don't seem to be able to locate an specs on it, like it's a big secret.

They're are following John Deere's Corporate practices, on how to screw the customer, and deny them service. lol

Is the Coleman brass connector a proprietary fitting,

It seems to be... I have tried to find one for the last three years...

I just searched again and found this...
