Is the 90° SAE 3000 Flanged Connection / BSP Female, Carbon Steel, Type D3 compatible with hydraulic systems using mineral and synthetic oils?

Yes. The 90° SAE 3000 Flanged Connection / BSP Female, Carbon Steel, Type D3 is compatible with hydraulic systems using both mineral and synthetic oils. It is made from galvanized carbon steel and supplied with an NBR O-ring, which is commonly compatible with a wide range of mineral and many synthetic hydraulic fluids. Its operating temperature range of -20°C to +100°C also covers typical hydraulic fluid service temperatures. Note: For specific synthetic formulations (e.g., phosphate esters, certain water-glycol blends or highly aggressive fluids), confirm NBR compatibility and material suitability with the fluid manufacturer or provide fluid details for verification.

Does the 90° SAE 3000 Flanged Connection / BSP Female, Carbon Steel, Type D3 require specific torque values for mounting screws to ensure a leak-free seal with the supplied NBR O-ring?

The 90° SAE 3000 Flanged Connection / BSP Female, Carbon Steel, Type D3 does not list specific torque values in the provided description. However, because it is supplied with mounting screws and an NBR O-ring intended to create a leak-free seal, proper torque is important to ensure correct compression of the O-ring without damaging the flange, screw threads, or seal. Recommended practice: - Follow the screw/fastener manufacturer’s specified torque for the screw size, grade and thread engagement used. - If manufacturer torque data for this exact assembly is unavailable, use standard torque charts for the screw material and size, and apply conservative torque to start, increasing incrementally while checking for uniform flange contact and O-ring compression. - Use a calibrated torque wrench and tighten in a star or cross pattern to ensure even loading. - After initial assembly, perform a pressure/leak test at working pressure and recheck torque after a short service interval. If you need precise torque figures, request the screw size, grade and thread details from the supplier or ask the manufacturer for recommended mounting torques for the Type D3 assembly with the supplied NBR O-ring.
