Nigo Industrial Co. 2451DE Series Forged Brass Ball Valve, Standard Port, Rated to 600WOG, MALE x FLARE (1/2" MIP x 1/2" FL)

The valve is exactly what I needed to install a shut-off for my water heater. It appears to be good quality and works well. Only negative is that it took a long time to arrive.

they work fine.

Not much to say, but it works as it should and was well manufactured with no sharp seams or bad threads.

This valve has 1/2 inch Male pipe thread and 1/2 inch flare fitting without needing additional adapters. The extra adapters add additional connections which are subject to leaking which is not good for gas connections. Quality valve and good price.

Great valve except that it has a steel screw that may rust holding the handle in place.

Good quality threads, no leaks (but my application is low pressure), handle turns easy.

Gas valve works as described with a 1/2 inch male pipe thread to a 1/2 inch male flare on the other end. Easy to turn on and off, no sticking what so ever.

Bought four of these for a project. Have them on a four port gas manifold. Valves are small enough to screw onto the manifold without hitting each other and valves open/close without interfering with each other.
