Help with pipe connection & terminology
All--
Another dummy question, this time concerning pipe connections. I need to connect a male 7/16"-24 to a male 1/2"-18. How do I do that? What is (are) the proper name(s) of the component(s)? (I got lost in the weeds.)
Picture of what I want to connect . . .
Thanks!

Type "pipe fittings chart" into Google images and you'll find lots of help, like this...

Re: Help with pipe connection & terminology
The needle valve is threaded in 1/4" compression (ferrule) sleeve, which is 7/16-24, with a 20 deg seat.
The fitting next to it is 1/4" NPT, which is 18TPI, and would measure about 1/2". (1/4" pipe measures .54" OD)
I know of no single adapter to connect the the two together.
They do make needle valves, in 1/4"NPT x 1/4" compression tube. Might be the way to go?

This is why God made solder

Re: Help with pipe connection & terminology
It's called a " Reducer Pipe Coupling "
normally they have a 1/8 or 1/4" reduced sized, so a 1/2 to 3/8 would be common
Your 7/16" thread is weird , so you may have to get a 1/2 to 3/8 and open up the small end

The vendors are screwy.. this is listed as a elbow , but it is not

Thank you for the help! That will get me going.
Bill S, solder is how I've always done it in the past. All my soldering stuff is in a box I have yet to unpack. Looks like that box might be next.

Re: Help with pipe connection & terminology
If that is a 1/4-inch compression fitting on the valve, I'd see about soldering a 1/4-inch tube into the male-to-male coupler and use the compression fitting to couple the two together. If the hole in the M-to-M coupler is too small, drill it out half way. If it is too big, insert a wood dowel in the other end to the middle and tin 1/2-inch of the copper tube. Then stand the coupler on the dowel, flux the hole and set the tube, centered, in the hole. Apply heat to the end of the coupler until solder flows easily into the gap between the tube and coupler. But I guess I am a cheapskate with no knowledge of the pressures or tension between the pieces that might be involved.

Not likely a good candidate considering it is for 3/8" tubing.Bill Shields wrote: ↑Sun Feb 26, 2023 7:10 am https://www.mscdirect.com/product/details/01601665

Re: Help with pipe connection & terminology
Disassemble the valve
Cut the thread down to a smooth tube.
Bore the other fitting to match.
Solder them together
