The correct minimum size for factory-installed tubes on outlets is 1/4 inch NPS. This size is established to ensure proper flow rates and pressure for various medical gases used in healthcare settings.

Using a tube of this size allows for adequate delivery of gases such as oxygen, nitrous oxide, and medical air without the risk of obstruction or pressure loss that may arise with smaller diameters. It balances the requirements for safety and efficiency in the medical environment.

This specification is critical as the medical gas supply system must be capable of meeting the varying demands of medical procedures while providing a reliable source of gas at the point of care. Larger diameters may be convenient in certain applications, but the 1/4 inch NPS is the established minimum to ensure compatibility with standard equipment and practices in medical gas installations.
