Propane Quick Disconnect Problem

At the end of my propane line there is a rectangular housing that has one quick disconnect, and a plug at the end of the supply line. I purchased a quick disconnect and fitting today to replace the end plug. When I tried it, the propane would not feed to my BBQ. I had already removed my regulator from my BBQ, as Iíve been using it on a quick disconnect in the middle of the trailer for some time now. At first I thought it was a defective quick disconnect, but it worked on the one for the refrigerator coming off the same housing.

My two questions are:

1). What is that housing called?

2). Is the end connection different from the side connections? Maybe the side hole is restricted, and the end one is not, causing too much flow to the appliance causing an automatic shut off? The regulator is at the tank, so this wouldnít make sense to me.

Iíve attached a pic. The blue tape is covering the end connection hole. Never mind the C Clamp, it is there so add support while I removed the end plug.

That block appears to be just a "T" for the gas line made such as to be able to bolt it to the frame.
If both halves of the quick coupling are not perfectly matched they may connect but not push in far enough to allow gas flow. You may have to buy a complete matched quick coupling.

Thanks TT. I think you may be correct about the connection not being good for some reason. I will try a new QD, and if still not good buy a set where they come together. I didnít add, I was trying to diagnose it going between one that I knew worked and th new one. One time the new one worked, then I bolted it up and never worked again, even after unbolting from frame. The ball as opening as I could see it when it was apart, so the male to female may not have been siting well enough.

I would suggest to recruit someone to help you to turn gas on while you check the opening where the blue tape is to determine if the side connection, as you call it, is energized...Or better yet use a gauge...

As far as the quick disconnect is concerned both the male & female should have a part number on them so you can distinguish if it can be matched to another fitting, whether male or female...Also make sure you have a GAS quick disconnect and NOT a WATER quick disconnect...They are different...Or at least that is what I was told...

Good luck...

Thanks Tommie. I did get it at an RV shop. I will take your other suggestions. Thanks!

Looking at your picture, I noted that it is like mine. I too had a struggle with the propane coming to my Grill when connected.
There is an on / switch on the fitting. Note the tab in the picture that is sticking toward you. You need to have that turned off to insert the snap fitting into place. It will not seat. Once the extended hose is fitted, now turn on the gas using that switch.

Thanks Wildasindrive, I use it as you described. Iíve been using the bbq with the factory installed QD in the middle of the trailer, but that location is inconvenient as it puts me near my entrance door and sometimes smoke will go into the trailer.

Iím hoping to get this QD installed near the end of the trailer so I can keep the bbq in the rear. If not, I will buy a 12í extension hose to go with my 10í hose and run it out o the rear. Iíll be attempting it again on Tuesday with another QD first.

Steve, are the connectors all the same brand/make? In other words, all from the same company?
I had trouble getting some to work awhile back. Come to find out they're not all the same. Even ones for LP. I ended up getting all my fittings from Camco. End of problem.

Thanks Lloyd. Tt said the same thing basically. I bought the pieces separately so that could be the problem. I already have the hose, so I would have to buy the hose with the QD male and the QD again all of the same I guess. Thanks.

You should be able to buy the setup in my picture and screw it onto your hose. If I'm understanding what you are saying correctly, it should work that way.
