Water Pump/Hose Adapter

This is for water pumps(in my case "Vida XL") or "steinbach" 3 way valve or these big pump valves(see picture). On the other end i want connect intex hoses(38mm).(see picture)

The goal was to maximize the water flow and i dont want to use all these bad fitting adapters anymore.

The only thing you have to buy is sealing rings ~52mm outside diameter. I reused the sealings from the bad fitting adapters. ;)

Bottom thread outside diameter is 59mm.
Top thread outside diameter is 47mm.
