What should be done to the ends of a cut tubing?

• A. Roughen the surface for better adhesion
• B. Seal it with a cap
• C. Deburr it to remove sharp edges
• D. Coat with a protective layer

Answer: (C)

Deburring the ends of a cut tubing is essential for ensuring safety and functionality. When tubing is cut, the edges can become sharp and jagged, which poses a risk of injury during handling or installation. Removing these sharp edges through a deburring process creates a smooth finish, reducing the risk of cuts or damage to other components when the tubing is connected to fittings or other parts of a fluid system.

In addition to enhancing safety, deburring also improves the fit and sealing capability of the tubing, which is critical in fluid systems where leaks could result from improper connections. A smooth edge allows for better engagement with fittings, thereby promoting a tighter seal and overall integrity of the system.

While other actions, such as sealing the tube with a cap or coating it with a protective layer, have their respective uses, they do not address the immediate concern of sharp edges that can result from cutting. Roughening the surface may help in adhesion applications, but it is not relevant in this context, where the focus is on safety and proper fittings. Therefore, deburring is the most appropriate action to take with the ends of cut tubing.
