Help with Hex Bushings


So we've been trying to install a new gas dryer, but the lines don't match up and we've been having a hell of a time finding the right size hex bushing.

We know one side is definitely 1/2" Female, but on the Male side 1/2" is just a bit too big and 3/8" is too small. Is there anything in between?

If anyone can help with this, that would be amazing.

Umm...I'm not sure. >_> I'm not great with this sort of thing, it's our first house.

Here's a picture of the gas line: http://i52.tinypic.com/2ezplc1.jpg

Does that help?

Sounds like you might need a 1/2 MIP x 1/2 flare nipple

Looks like you need a new gas flex.
This will be safer replacing all fittings that come when you buy a new gas flex.
Both ends need to be the same.

you have a pipe at the back of the dryer. You need a fitting that is female NPT to fit onto that nipple and flare fitting on the other end so the flex will seal onto that.

It will look something like this:

flare fittings for gas lines are standardized throughout the US. There should be no problem using various manufacturers products. As well, I can't say I have ever seen what you are suggesting. Maybe you could provide a link to a gas flex line that comes with the necessary adapters included.

Nap Love the photo.

Here is one from Brasscraft that will not match the one from Dorment
even thought the 1/2 side is a NPT

there is no way that all flair fittings for a gas flex is the same.
If you were installing Copper pipe all flair fittings would work.

Its a $10.00 part that is not worth have any chance that you could Have a gas leak.

yes, there is. Flare angles and thread dimensions have been standardized many years ago.

Now, there are a couple different flare angles used for different purposes but flares used for gas lines are standardized. As long as the parts purchased are intended for use with gas supply lines, they will match properly.

I see nothing wrong with what you have linked though. In fact, it appears the adapter is steel which would be preferable. Brass female fittings can split when overtightened.

The Flair angle may be the same.
But I have installed many stoves in my day and when the old stove was removed by the appliance company and they disconnected the old gas flex from the stove they would alway keep the IPS to Flair adaptor.
I have tried this many times its not the flair that will not match its the its the new male and female thread from each manufacture that was my issue.
The two thread were close but they were not the wright fit and with Gas Close is not OK!

sorry you have had that experience but the flare angle and fitting diameter as well as the threads both pitch and diameter both minor and major are all standardized. With cheap parts, you may experience a lack of quality that is necessary for a proper fit. When using quality parts, there should be no such problem.

Bottom line; the OP needs to be certain there is no leak once they have assembled their installation. Whether they purchase a line with adapter included or purchase an adapter separately, just make sure it doesn't leak once installed.

fair enough?

Standardized isn't necessarily standard. Where I work we build a lot of military equipment. We learned the hard way than even MIL-SPEC electrical connectors will often not assemble properly if all the pieces aren't from the same manufacturer.
