Which type of connection is most commonly used for testing gauges?

The most commonly used type of connection for testing gauges is the 1/4" female connection. This size and type are prevalent in the industry for several reasons.

First, the 1/4" female connection provides compatibility with a wide array of pressure gauges, which are typically designed to use this standard size. This makes it easy to interchange gauges during maintenance or inspection without requiring specialized adapters.

Secondly, the design of the 1/4" female connection allows for a secure fit, which is essential for accuracy in pressure readings. A secure connection helps prevent leaks that can lead to inaccurate measurements, ensuring the safety and reliability of the system being monitored.

Moreover, the compact size of the 1/4" female connection is functional in many installations, particularly where space is limited. This small footprint enables easier integration in various setups, especially in boiler applications where multiple gauges may need to be installed closely together.

In contrast, the other connection types, such as screw-type or flanged connections, may also be used in different contexts but are not as standard or practical for testing gauges. Flanged connections are typically utilized in larger, high-capacity systems or for components requiring higher strengths, while screw-type connections may not provide the level of precision
