32 oz spray bottle to npt adapter 1/4 3/8 1/2"

I needed a reservoir to test a water manifold and have access to a supply of water bottles.

I made room for a 24x2.4mm o ring because pet threads probably aren't meant to seal below the water line and i needed my bottle flipped upside down.

No o-ring on the npt end since its a low/no pressure application so I recommend PTFE tape if you use this.
