Hi Bo, to help you find your answer we recommend checking local codes or contacting your local plumber. When it comes to differing types of fuel and flammable liquids it's best to consult those with the most up-to-date knowledge of what your region's authorities have determined is the appropriate project materials. We hope this helps with your purchase.
Hi ROB, there is not a copper fitting that will fit inside of the existing copper tube. We recommend checking local code before starting your project, however you might look at the dielectric unions as a potential solution to your problem as they come with a copper sweat connection to a threaded iron pipe connection. We hope this helps with your purchase.
L is a heavier pipe than M. In household plumbing L is more commonly used. M can be used in lighter projects.
Hi Terri, we don't recommend using copper as a building material for this application. Copper tubing is soft and malleable and not designed for holding weight. If you like the copper look, we recommend using either galvanized or black fittings & pipe, cleaning them then spraying them with a copper metallic spray to try & get as close a look as possible. We hope this helps with your purchase.
Hi Nan, this is a hard length of Copper Type L tubing. Typically Streamline displays hard lengths with the straight tube (i.e. this items photo) and soft tubing by displaying a coil image. We hope this helps with your purchase.
Dear Nick, You are correct, type L (aka BLUE) pipe is thicker in the walls than the type M pipe(aka RED). The engineering specification is that L is 0.040" thick, and M is 0.028" thick, which is about 40% thicker for the L type. I had to research this because no human in the store knew what the difference between the two types were. As you probably already understand, the OD of the pipes must stay the same for L & M, so that the fit into elbows, tees etc remains constant for both types, thus the ID must be less for the Type L. Just to confirm for you, I just now remeasured the Nominal 1/2" copper pipe, type L (Blue) and here are the results OD = 0.625", ID = 0.545" thus the wall thickness is indeed 0.040". Now as to the organization of HD and their website data for products, I find gross contradictions and errors in about 30% of their data on the website. I believe that they are underpaying bored interns and high school students to input data, and most people don't pay attention or think about their answers or the work that they are inputting in the computer database. This forum (Q & A) will not correct the error that you found. I have done this by calling Home Depot and taking the time to get to a data base manager and tell them to correct the problem. They will fix it, but you will lose another 1/2 hour of your life, fixing their error. Good luck! Mr "Doitmyself"
Hi Rebecca, if this is intended for decorative vs utility use then you can use this outdoors. Just beware that exposure to the elements will begin to corrode this pipe turning it green. We hope this helps with your purchase.
The red is thinwall for heating pipe the blue is thicker wall for drinking water. Heating pipe is oxygen poor so it doesn't corrode as fast.
Hi Billboy, Mueller Streamline pipe is manufactured in the USA. We hope this helps with your purchase.
