Back on hoses.
When you have made one you need to check it on an "anti-confusion" jig.

They are a set of connection blocks with the appropriate NIST on one end and the Schrader on the other.
This makes sure you have picked up the right bits from the connectors box and not put air on one end and oxygen on the other for example.
