The correct step after slipping the nut on the tubing is to insert the end of the tubing into the correct-sized hole in the flaring block. This is a crucial part of creating a flare on the tubing that will ensure a proper seal when connecting to another component.

By inserting the tubing into the flaring block, you’re preparing it to be shaped into a flare that can effectively mate with fittings. This step is essential for applications where the integrity of the connection is vital, such as in hydraulic or pneumatic systems.

Cutting the tubing to the desired length is typically an earlier step, as you want to ensure the tubing is the appropriate size before working on flaring it. Applying tape to the threading of the nut and lubricating the nut may be helpful in specific contexts, but they are not the immediate next steps after positioning the nut. The focus here is to establish a functional flare as the next step in the process.
