Nút bịt ren ống (đực) 1/2" và 3/4"

I faced the need to prepare my garden water supply for winter with negative temperatures. I removed the taps and realized that the holes would not be protected from dirt and debris. I decided to make these simple plugs with standard pipe threads 1/2" and 3/4".

This is my first simple model that can be useful to this community.
