10 Pack 1/2 Inches x 8 Inches Black Malleable Steel Nipples Fitting, DIY Steampunk Industrial Vintage Style.

These are the pipes used to make the Sanlaki 3d printed gunstock for VR gaming, and they are great quality for that purpose.I had to knock off a star though because mine arrived a little rusty and that rust transfered to my hands and onto the 3d parts of the printed gunstock as I was assembling it, which is kind of disappointing. Since I 3d print though I have lacquer and can just coat the pipes, but it feels like I shouldn't have to do that with a brand new product.Other than that though, I am very happy with their quality and they will server their purpose very well.

I was expecting schedule 40 nipples and did not notice anything that said what thickness these were. So, I wasn't planning to use them for water, oil, or gas, but I was expecting standard schedule 40 wall thickness. It was a fun challenge welding on these nipples. After I blew a hole in the first nipple I made some adjustments and they worked out just fine. These are great for wheelbarrow repair, but not so much for plumbing.

These will not match with other 1/2" pipes that are 8 inches. It comes in at 7 3/4" which can throw off your structure if mixed with other vendors who do measure a true 8 inches.

These are advertised as 8 inches, but are only 7 3/4 inches long. Were not long enough for my purposes so had to return them.

These pipes are thinner than a normal 1/2” pipe

These look good and work well. Great price and no issues with them at all.
