Why should you avoid applying excessive force when assembling glass joints?

• A. Excessive force can crack or shatter glass.
• B. Force helps ensure a tight seal.
• C. It prevents lubrication.
• D. It reduces assembly time.

Answer: (C)

Excessive force is avoided because glass joints are fragile and can crack or shatter under stress, especially at the fine connections where parts mate. The safer approach is to align the joints carefully and seat them with gentle twisting or turning, rather than forcing them together. A small amount of lubricant is used on glass joints to reduce friction, help the pieces slide together smoothly, and promote a consistent seal without needing to apply brute force. Forcing a joint can damage the glass, misalign the joint, or push contaminants into the system, whereas proper lubrication and gentle, controlled assembly lead to a reliable seal with far less risk. If a joint feels resistant, stop, check alignment and cleanliness, and retry with appropriate technique rather than applying more force.
