Slurry tanker small pipe fitting

[Deere342]

We have an old slurry tanker with a spare 6" opening blanked off. We are think of using it as a large mobile water tanker for watering a nursery.

Looking at this NC tanker there is a smaller fitting to the right at the rear. What is this called? Who sells them? Struggling to find such a fitting on eBay or just the web.

Thanks.

All you need is to cut a hole in the square plate and weld in a piece of 2" BSP threaded end steel pipe,and fix on a 2" BSP gate valve , or the rotating ball type valve,
