Which type of connector should connect the medical air compressors to their intake and outlet piping?

• A. Compression
• B. Insulated
• C. Flexible
• D. Dielectric

Answer: (C)

Vibration control and the ability to accommodate movement between equipment pieces are essential when tying a medical air compressor to the intake and outlet piping. A flexible connector is designed to absorb compressor vibrations, allow small misalignments, and handle thermal expansion and contraction without transferring stress into the rigid piping. This helps prevent leaks, fatigue of joints, and excessive noise, keeping the medical gas system reliable and safe.

Rigid compression fittings would transmit vibration and stress directly into the piping, increasing the risk of leaks and failures. Insulated connectors focus on thermal insulation rather than providing movement, and dielectric connectors are meant for electrical insulation, not gas piping connections. Therefore, a flexible connector best meets the need for protecting the system from vibration and movement.
