LDR Industries 310 CO-2 Coupling, 2-Inch, Black

I purchased 1/2" black malleable elbows from another seller here on Amazon that were improperly machined, causing the black pipe to bottom out before the threads sealed properly. Doing a pressure test, my propane black pipe distribution for my cabin wouldn't hold pressure.Discovering the problem was improperly machined elbows, I ordered these "LDR 312 E90-12 90 Degree Elbow, 1/2-Inch" and completely disassembled and reassembled my propane piping system. I was very pleased after all the effort to find that none of these elbows leaked. My system holds pressure as it should.Whether you're making furniture or building a DIY natural gas or propane black pipe system, these elbows are ideal for either. They are heavy duty and properly machined with a good finish and quality control. I highly recommend them.

As others have mentioned... a few times... the threads on many of the flanges are not straight. They're not perpendicular to the base. I ordered 16 of them and probably at least half were in some way warped or angled. It's just a desk, so they still work for what they are and I'll be able to adjust the threads and other pieces enough to be stable. But if I were building anything else, they wouldn't work.

Worked great . Some measuring so elbos and rods are attached with a little room to come apart when changing curtains out.

This product is NOT as described. I ordered 20 for a project and they all arrived with CHINA engraved on the outer face. Since they will be very visible where I intended to use them this was not acceptable to me. Had I known what they would actually look like I would not have considered ordering this product. The stock photos and descriptions do NOT reflect the actual product and I am not satisfied with what I received. The customer service was cordial but unhelpful.

I used these for building a pipe lamp switch

Great product!!!!

Perfect - exactly what it is advertised as . . . and for a decent price . . . which makes me wonder why these things are so freaking expensive at Home Depot and Lowes . . . it makes no sense! Thankful to find this outlet for them, as I use them for creating light fixtures and need them often . . .

Quality fittings

Good quality. No different from the ones you can get at Home Depot.

As advertised
