1/2 tuuman metallirengaspohja 58030

This little metal base is exactly what I needed to turn a spare sprinkler head into a proper lawn soaker. The 1/2-inch threading fit perfectly, and the heavy-duty ring feels solid enough to handle years of backyard abuse.

I screwed a spare impact head onto this ring and it made a way better sprinkler than the plastic one I had. The metal is thick enough that it doesn't wobble when the water's on full.

The metal threading bit into my old brass sprinkler head without stripping, which was my main worry. It's stayed put through a full summer of watering the back field, no leaks at the joint. Solid little piece for the price.
