Female Garden Hose to 1/2 Inch Hose Barb

thingiverse

3/4-11.5 NH (Standard garden hose thread in the US and Canada) to 1/2" hose. This design can accept a standard garden hose washer to create a seal between the drain connection and this adaptor, but this may not be required in some cases. This was designed for a small indoor air conditioning unit, but will work in many drainage applications. As this is a 3D printed part, I wouldn't advise putting it under any real pressure.
