Metric Hydraulic Hose Fittings: Powering Performance in a Globalized World

Metric hydraulic hose fittings charts are your roadmap to navigating the vast world of these essential components. These charts provide a wealth of information, empowering you to select the perfect metric fitting for your specific hydraulic system needs.

Decoding the Metric Hydraulic Hose Fittings Chart:

A typical metric hydraulic hose fitting chart will typically include several key columns:

• Fitting Series: This identifies the specific fitting style or family (e.g., S Series, ISO 6149). Each series has its own characteristics and pressure ratings.
• Dash Size: This indicates the hose bore size (inner diameter) that the fitting is designed for. Common dash sizes include -4, -6, -8, etc., with higher numbers corresponding to larger diameters.
• Thread Type: This specifies the type of thread used on the fitting, ensuring compatibility with your hose or component. Examples include ISO 1179-1 (metric parallel), ISO 9974-1 (metric tapered), etc.
• Body Style: This describes the fitting’s configuration, such as straight, elbow (45° or 90°), tee, reducer, or flange. Each style serves a specific purpose in directing flow within the hydraulic system.
• Material: This indicates the material used to manufacture the fitting (e.g., steel, brass, stainless steel). Material selection depends on factors like pressure rating, operating environment, and fluid type.
• Pressure Rating: This specifies the maximum pressure the fitting can safely handle. Choose a fitting with a pressure rating exceeding the maximum pressure in your system.

Beyond the Basics:

Some charts might include additional details like:

• Dimensions: This provides specific measurements of the fitting, such as overall length, thread diameter, and wrench flats, which can be helpful for installation purposes.
• Part Numbers: These unique identifiers allow you to easily locate and order the specific fitting you need from a manufacturer or supplier.
• Torque Specifications: These indicate the recommended tightening force for the fitting’s threads to ensure a secure and leak-proof connection.

Utilizing the Chart for Informed Decisions:

Here’s how you can leverage a metric hydraulic hose fitting chart:

1. Identify System Requirements: Determine the hose size (dash size), thread type (compatibility), and pressure rating required for your hydraulic system.
2. Consult the Chart: Look for fittings that match your hose size, thread type, and pressure rating needs. The chart will display compatible body styles and materials to choose from.
3. Consider Additional Factors: Beyond the basic specifications, consider factors like space constraints (fitting body style), desired flow direction (elbows, tees), and potential environmental concerns (material selection).
