Hey Guys!
This is a very strong 1 inch pipe adapter for water pipes. I made this so i could use some old 1 inch water pipes as the legs of my new workshop desk!
You could probably also use this for a pullup bar or something similar...be creative!
The threads are a DIN G33.249x2.309 and a 1'' NPT, the other 2 Versions have no thread but you could glue something in!
If you need a different thread let me know and i will update it with other threads!
