I am making a stand up desk with a galvanized pipe frame. After having originally purchased pipe fittings at Lowes and then returning them I ended up purchasing these Anvil pipe fittings. There is a drastic difference between these and the pipe fittings at Home Depot or Lowes.The Chinese made piece of crap pipe fittings purchased at Home Depot or Lowes come very greasy and after properly cleaning has the tendency to rust.In comparison, the pipe fittings purchased from Anvil are noticeably higher quality and are so clean that you could lick them. Trust me, I was so excited when I received them and noticed the quality that I did (do not try this at home).Do you want to spend time cleaning and removing rust or do you want to start your project immediately after receiving your pipe fittings?It is truly difficult to say much about a steel pipe fitting nipple, but here goes: It looks like it will work exactly as it was designed and planned to work, as well as for my needs. Additionally, delivery was timely and product is exactly as advertised/ordered under Amazon Prime. Perfection!These are premium fittings with correctly machined threads, and are clean and ready to install. The imported fittings from the box stores often have short threads (less thread engagement) and are packaged in "mystery" oil. The cost difference is negligible - go for Anvil.fineGreat pipe, needed it for protecting cabling run along a wall. Cheaper to use pipe rather than buy waterproof cable.Needed this for an outside railing the price was right much cheaper then the big box storesexactly as describedProduct ok, but shipping shortages made me miss my project
