Anderson Metals - 56103-04 Brass Pipe Fitting, Coupling, 1/4" x 1/4" Female Pipe

It is a very well made product. I would buy it again!

Works just fine

I had to make an extension pipe for a propane manifold. This coupler saved the day! The hex nut fittings they make are 2nd to none. I have been using Anderson Metals products for quite awhile now. I have never had one fail! I recommend these to anyone that has a plumbing job.

I purchased a propane quick connect hose, and then discovered I could not connect to a LPG generator from a 5th Wheel quick connect outlet. This double female coupling allowed me to make the connection. I removed the safety quick connect valve, installed the coupling, and attached a 1/4 inch male quick connection, which I inserted into the generator safety coupling valve. Difficult to find on Amazon, and local hardware stores were clueless on LP quick connections.

I got perplexed installing a water hammer arrestor. The water hammer arrestor was labeled "1/4" O.D." But its male fittings were 1/4" inside diameter (I.D.). I couldn't understand why this 1/4" I.D. female coupler slid over the male fittings. The male fittings were 0.43" and this female couple is 0.455". After spending way too much time searching on the Internet I put on my mask and went to Home Depot. The plumbing aisle employee told me that the water hammer arrestor had a compression fitting. I went home and found a YouTube video explaining how to connect compression fittings. Twenty minutes later I'd installed my water hammer arrestor, with no extra parts. So I never used this brass coupler but it looks nice. :-)My pipe is 0.25" inside diameter and the outside diameter of the male threads are 0.43". This coupling has an inside diameter of the female threads of 0.44". It slides right over my pipe without engaging. Apparently there are different plumbing "standards" where "1/4-inch" means different sizes. The specs should say what the diameter of the threads are and what pipe it threads onto.

Needed this to complete the conversion of a Weber Q model to connect to my camper's LP system.

There's not much to say about something like this, but this is well made with no burrs or imperfections. I used it for an air tool connection, and though the threads are not very deep on either side, I simply used some Teflon tape sealant and accomplished what a rubber o-ring or washer otherwise would have. Would buy again if needed. This will last a lifetime, ​though.

purchased one. it arrived one day earlier then stated, was in perfect shape, and fit my 3/4" male pipe perfect. so i ordered two more. they also arrived earlier than stated. thank you.
