1/2" 3-Way (L-Port) Ball Valve, NPT Female Brass Ball Valve with Seal Tape

Can't find these 3-way valves local. Needed one to install a heater in a side by side UTV. Worked great.

I use this valve for the output of my shop air compressor to depressurize the regulator and air lines when the shop is not occupied. One end port connects to the tank and the other end port is the exhaust. You can install a muffler or just leave the exhaust open. The center port goes to the regulator. Blow through the valve to make sure it is right. One valve position sends air to the regulator, and the other stops air to the regulator and vents the regulator and hose to atmosphere.

Like all others said, poorly made threads so every connection point leaks

I have used it daily for a month or so with no complaints. I expected it to ether go straight through or go out the side, but that isn't possible. Tha path of the water will always take a 90° turn. Depending on handle position will choose which two neighboring ports will be connected, which will leave the 3rd port closed off.

I used these for a bypass to my air cooler for my compressor. The valve body seems to be working fine. I don't really have a way to confirm there's no leaking with my configuration, but if there's a leak, it's not noticeable in my setup. However, the threads are not NPT, and it is extremely difficult to stop leaks. Especially to the cheap adapters. However, even the high quality true NTP pipe and adapters took an extreme amount of torque, even with tape and pipe dope. I was eventually able to eliminate all the connection point leaks, and for the price, and what you get, i think they're a decent value.

Upgraded old camper leaking 3 way valves, worked perfectly.

Works well

This was so perfect for what I needed it for. I would buy it again. It arrived quickly and in perfect condition.
