Midline Valve 6I342 Steam Radiator Valve; Air Vent Temperature Control; 1 in. FIP x Male Union; Brass

Worked well good construction. I was replacing an 80 year-old valve so it fits slightly different than the old one. I was able to get it to work.

Previous kne started leaking water. Checked very throughly with eyes and used even sharp knife to locate the crack but couldnt find. So decided to just replace because valves crack if radiator moves or swings. After pulled it out, I was able to find the crack on inner side of closing thread. This product has much thicker connecting thread area so it should hold more securely. I didnt have to tighten as hard as old one. It had a good grip of turns and sealed fine. This is a nice product with reasonable price.

Works

Good quality and trusted brand. Easy to install

I installed four of these on hydronic radiators in a house I moved into that was built around 1900. I'm sure the radiator valves were original, and they were completely non functional. I took a chance, and installed these without removing the original spud from the radiator. Three out of four mated up properly with no leaks. The fourth had the tiniest of leaks (like a drop every four hours) and I had to fiddle with that to get it right. Having adjustable radiator valves transformed the performance of my heating system and got rid of a huge imbalance in temperature from upstairs to downstairs. Yes, if you haven't done this before, it can be intimidating, and you need a couple of good pipe wrenches and a length of pipe to get the proper leverage, but these ancient valves came off with no damage and I did not need to heat the joints up with a torch. Just applied smooth and steady pressure.

Worked perfectly.

Direct replacement for my ancient radiators valve.

Used these to replace all valves on my old radiators. These are quality valves and have a good seal of them. I already notice a difference my radiators are much more efficient.

I can control the water going to my rad now
