Anderson Metals54056-0806 Brass Tube Fitting, Reducing Union, 3/8" x 1/2" Flare

I bought an Avenger wall heater which was Not as warm as I thought it would be but is a very sturdy heater. I found out that old heater was hooked up to copper tubing. So I needed Anderson Metals Brass Tube Fitting, Reducing Union, 3/8" x 1/2" Flare that is available at Amazon. I used Mr. Heater One-Stop Universal Gas-Appliance Hook-Up Kit to go from heater to brass tube reducing. I never put in gas lines before but with yellow tape put on clockwise on all male fixtures It was real easy. I put soap bubbles in all attachments and no leaks. I had to wait about 2 minutes pushing on startup knob before LP gas go to furnace but this fitting was exactly what was needed. This was the only place to get one of these fittings lowes home depot did not have them.

Exactly what I needed!I looked everywhere. I should have known to start here. I did go back to check other places again. This place has it all.I can't believe this was the only place.Quality is great! Flares fit good and tight.Very happy!!! I bought the nuts from them too, perfect fit, good quality!They saved my cooling tube extension!

I bought a 5/8 by 3/8 flare reducing union. What I received was something marked 5/8 by 3/8. So far so good, right? I have a 5/8 OD flare female and another 5/8 OD flare male fitting. They fit together perfectly.Edit: I decided to measure the reducing union but had to resort to a tape measure (I don't own calipers). The Anderson metals measured 7/8in thread to thread on the larger end, and that technically is correct according to SAE 45° sizing. I went and measured my other 5/8 OD equipment and found them to be 15/16in thread to thread. I've never been more confused in my life. I've finally discovered that 5/8in flare isn't just 7/8in. There's another 5/8in flare size that refers to 15/16. This 15/16 is some kind of newer revision used in gas appliance line hookups. It's still confusing and extremely poorly documented, to a dangerous degree. I don't think it's fair to give this product a bad review because of the disorganized nature of the flare fitting industry. Perhaps it will work for you, but be aware that this 5/8 flare measures 7/8.

Good quality product and works as intended. Box stores rarely carry a selection of brass, so this was nice to have a quick delivery when needes.

3/8 maleX1/2 male brass fitting, right size and installed.

1/8 mpt by 3/8 flare fit perfect on my fish fryer the hose went out and a new one that I bought didn't have where it would hook straight to it so I had to buy the adapter to go on it and it works great

5/8 to 3/8 flare fitting. Came in 1 day early. Works perfect. Hook up my outside gas line to a small propane tank with regulator. Saves $$!

scratches and pitting on flare faces. poor quality.
