Metric hose fittings are sized and measured using the metric system of measurement. Here are some key points to understand:
1.Thread Size: The size of metric hose fittings is primarily determined by the thread size. The thread size refers to the diameter and pitch of the threads on the fitting. Common thread sizes for metric hose fittings include M8, M10, M12, M14, M16, M18, M20, and so on. The size is usually expressed as "M" followed by the thread size (e.g., M12).
2.Thread Pitch: In addition to the thread size, metric hose fittings also have a specific thread pitch, which refers to the distance between threads. The pitch is usually expressed in millimeters (mm) and is denoted after the thread size (e.g., M12x1.5). The pitch value indicates the number of millimeters the fitting moves forward or backward with each full rotation.
3.Measurement Tools: To measure the size and pitch of metric hose fittings accurately, you can use specialized tools such as thread pitch gauges and calipers. These tools help determine the diameter, pitch, and thread profile to ensure proper fitting selection and compatibility.
4.Connection Type: In addition to the sizing and measurement, it's important to consider the connection type of the metric hose fitting. This includes whether it is a male or female fitting, the shape of the sealing surface (e.g., flat face or cone), and any additional features such as O-rings or sealing washers.
When working with metric hose fittings, it is crucial to match the fitting size, pitch, and connection type with the corresponding components, such as hoses, adapters, or equipment, to ensure a proper and secure connection. It's recommended to consult the manufacturer's specifications or seek professional guidance if you are unsure about the sizing or measurement of metric hose fittings.
