Additionally, the thread references many ways to transition from metric to inch and vice versa with readily available fittings. For example:
- Use Unifit - Threads into NPT, Rc, and G
- 5/16" OD is the same as 8mm OD but 5/16" OD fittings are available in NPT threads.
If you work with pneumatics and especially if you work in an environment with a mixture of NPT, Rc, and G threads then you will most likely find this tool useful.
