What Adapter For
Your answer

Garden hose to 1/2 inch pipe adapter

If the pipe has threads on the outside, use a 3/4" MHT x 1/2" FIP brass adapter: it screws onto the pipe and your hose screws onto it. Garden hose thread is about 1-1/16" across and 1/2" pipe thread 0.84", so they won’t screw together.

  • One end takes your hose, and the other screws onto the pipe.
  • If the pipe is connected to a water supply, shut the water off first.
  • Wrap thread tape around the pipe’s threads only, the same way the threads spiral (clockwise as you look at the end), starting at the first thread. Don’t tape the hose end. It seals with its rubber washer.

Hose thread is about 1-1/16" across and 1/2" pipe thread is 0.840", so one can’t screw onto the other.
