Does the Flange connection 90Â° SAE 3000 / GZ BSP, carbon steel, type C3 include mounting screws and an NBR o-ring for installation?

Yes. The Flange connection 90Â° SAE 3000 / GZ BSP, carbon steel, type C3 is supplied with mounting screws and an NBR o-ring seal for installation. The product description specifies a compact 90Â° SAE 3000 flange with external BSP thread, made of galvanized carbon steel, and includes the mounting screws and NBR o-ring.

Is the Flange connection 90Â° SAE 3000 / GZ BSP, carbon steel, type C3 suitable for hydraulic systems operating at -20Â°C to +100Â°C?

Yes. The Flange connection 90Â° SAE 3000 / GZ BSP, carbon steel, type C3 Format is specified for hydraulic systems and lists an operating temperature range of -20Â°C to +100Â°C, so it is suitable for use within that temperature window. Note that the sealing material is NBR (nitrile), which performs acceptably across this range but may lose elasticity below -20Â°C or above +100Â°C; ensure system fluids and application conditions (pressure, media compatibility, thermal cycling) match NBR and carbon steel with galvanization. If your system approaches the limits or uses aggressive fluids, consider verifying compatibility or selecting alternative seal/materials.

Can the Flange connection 90Â° SAE 3000 / GZ BSP, carbon steel, type C3 be used with different O-ring materials than NBR?

Flange connection 90Â° SAE 3000 / GZ BSP, carbon steel, type C3 is supplied with an NBR O-ring and is rated for operation from â20Â°C to +100Â°C. Whether you can use different O-ring materials depends on chemical compatibility, temperature range, pressure, and sealing requirements: - Temperature: NBR covers â20Â°C to +100Â°C. If your application requires lower temperatures (down to â40Â°C) or higher temperatures (above +100Â°C), consider alternatives: FKM (Viton) for higher temperatures (typically up to +200Â°C), EPDM for better low-temperature and steam/heat resistance (â50Â°C to +150Â°C, depending on compound), or silicone for low-temperature flexibility (down to â60Â°C) but limited pressure/chemical resistance. - Chemical compatibility: NBR resists oils, fuels and many hydraulic fluids. If the system uses phosphate esters, aggressive solvents, hot water/steam, brake fluids or certain hydraulic fluids incompatible with NBR, choose EPDM, FKM, or PTFE-based seals depending on the fluid. Check specific fluid compatibility charts. - Pressure and mechanical properties: O-ring hardness and compound affect extrusion resistance and dynamic sealing. Ensure the chosen material has adequate hardness and is suitable for the system pressure typical of SAE 3000 series connections. - Physical dimensions and gland fit: The flange likely expects the same O-ring cross-section. Replacing material is fine if the new O-ring matches size and is compatible with the groove and mounting screws provided. - Galvanized carbon steel body: No special restriction, but consider corrosion and galvanic compatibility in the system environment. Recommendation: You can use other O-ring materials than NBR if the material meets the temperature, chemical and mechanical requirements of your application and matches the original O-ring dimensions. Validate with supplier data sheets and, for critical systems, perform pressure and compatibility testing or consult the manufacturer.
