Fluid Connectors

Selection of Fluid Quick Connectors

The selection of quick connectors generally follows the “STAMP” principle, which stands for Size, Temperature, Application, Media, and Pressure, to choose the appropriate quick connectors.

1: S (Size): Consider the quick connector's diameter, installation dimensions, structural type, and mounting interface.

2: T (Temperature): Understand the temperature of the fluid medium and the ambient temperature to select suitable sealing materials.

3: A (Application): Take into account the operating conditions of the quick connector, whether it's for static or dynamic connections, whether it will be connected and disconnected under pressure, and the interchangeability of the quick connector.

4: M (Media): Clearly identify the type of medium used in the system, as it relates to whether the main material of the quick connector and the sealing components are compatible with the medium.

5: P (Pressure): Clearly define the maximum operating pressure of the system and the maximum pressure drop allowed through the quick connector.

Key Points for Selecting Test Couplings

1. The Characteristics of the Testing Medium

Different testing mediums require varying testing couplings for compatibility. Therefore, when purchasing testing couplings, it's essential to understand the characteristics of the medium being measured, such as temperature, pressure, flow rate, and the medium's acidity or alkalinity.

2. Considering the Measurement Environment

Different measurement environments demand different testing couplings for compatibility. For instance, some mediums might be corrosive, and certain situations could necessitate high-temperature or high-pressure testing couplings for adaptation. Consequently, when purchasing testing couplings, it's crucial to clearly define the specific requirements of the measurement environment.

3. Addressing Measurement Precision Requirements

Diverse measurement precision requirements call for testing couplings for compatibility. Thus, when selecting testing couplings, it's important to specify the exact measurement precision and then choose an appropriate testing coupling model accordingly.

4. Budget and Maintenance Costs

Different models of testing couplings come with varying prices and maintenance costs. Hence, when purchasing testing couplings, it's necessary to consider suitable models based on one's budget constraints.
