Gas Flex Connection Between Burner and Manifold

[joe4444]

I ordered 3 "1/2" O. D. (3/8" i.d.) 304 Stainless Steel - Gas Flex Connectors" with the "3/8"fip x 3/8"fip" connections from http://www.plumbingsupply.com/gasconnectors.html. They are to go between my gas manifold and hurricane burners with "Natural Gas Conversion Kit for Blichmann Floor Burner" on my new single tier. Both the needle valve/orifice and the output from each of the 3 T's in the gas manifold are 3/8" male flare fittings.

The flex lines do not actually come as pictured, as the ends are 1/2" female flare and there is a 1/2" male flare (by 3/8" female flare) that screws in.

The problem is that the threads on the 3/8" female flare are too deep, and when screwed into the 3/8" male flare connected to the manifold (http://www.homedepot.com/p/t/100617...toreId=10051&N=5yc1v&R=100617064#.UUKJGheOSSo), there is still a gap between the flare fittings that are suppose to form the seal.

Did I order the wrong parts? Or is there anything I can (cheaply) do to fix this?

Thanks so much.

The 1/2"FL x 1/2"MIP isn't 3/8" female flare. It is 3/8" FIP.

Here is what you need to make those lines work.

Edit: I get it now. Replace the adapted that came with the hose with the one you linked to. Thanks so much.


I guess I am still a little confused on the terminology. I understand pipe thread fittings, but maybe not the difference between pipe thread and flare and FIP/MIP.

So would that "3/8 FEMALE FLARE X 1/2 MALE FLARE BRASS ADAPTER" screw onto the home depot part between it and the flex tubing piece? If so, what is the difference between this piece and the one I already have and am trying to screw into?

The attached photo is what came from the plumbing supply that I was trying to attach to the fitting from home depo.

I'm a little dense at this stuff, thanks for the help.

You got it.
