25 Pcs Black Carbon Steel Pipe Plug Fitting Assortment Kit, 5 Sizes 1/8" 1/4" 3/8" 1/2" 3/4" NPT Male Internal Hex Thread Socket Pipe Plug for Sealing Pipe Port

look good and fit good

I am building a restomod of sorts and there are quite a few vacuum and sensor ports that I will not be using, but I hate the look of brass and I didn't want any plugs sticking out like traditional NPT plugs. these Plugs look great and fit perfectly, all you have to do is add the sealant of your choice and sit back and enjoy the cleaner look.

The KUANVE 20 Pcs Stainless Steel NPT Pipe Plug Fitting Assortment Set has all of the common sizes for general household, and Light Industrial applications. KUANVE offers this set made of Stainless, Brass and Iron. I opted for Stainless Steel for my application, High Carbon Steel Manifold. The pipe plug profiles are NPT tapered, they are made of quality materials. I used the 1/4", 1/2", and 3/4" on my project with no issues. I am very happy with the quality and quantity of the product.

Nicely machined

This is a nice set. You get all the common sizes for SAE (non metric). They have a hex recess for use with standard Allen wrenches. To use them you just tape them with some Teflon tape and install them. The threads seem smooth and they thread in well.
