Is the DKR-F hydraulic end, type ZBW140, AISI 304 steel compatible with standard BSP female fittings and which flat gasket thickness is recommended?

Yes . the DKR-F hydraulic end, type ZBW140, AISI 304 steel uses an internal BSP (BSPP) thread and nut designed for connection with standard BSP female fittings. Sealing is achieved by a flat gasket (flat sealing), so a compatible BSP female must accept a flat-faced sealing surface and the appropriate gasket between the male face of the fitting and the female counterpart. Recommended flat gasket thickness: use a flat gasket of 0.5â1.0 mm thickness made of a suitable material for the application (e.g., NBR for general hydraulic use, FKM for higher temperature/chemical resistance). Start with 0.8 mm as a general-purpose choice; thinner (0.5 mm) may be acceptable for precise metal faces and lower pressure, thicker (1.0 mm) for older/rougher faces or higher sealing demand. Ensure gasket OD/ID match the fitting sealing faces and verify compatibility with fluid, temperature and system pressure.

Does the DKR-F hydraulic end, type ZBW140, AISI 304 steel require a specific torque value when tightening the nut for flat sealing?

No specific torque value is provided in the description for the DKR-F hydraulic end, type ZBW140, AISI 304 steel. The fitting uses flat sealing with an additional flat gasket and is designed for crimping with a sleeve appropriate to the hose type; final sealing depends on correct gasket seating and proper crimping rather than a specified nut torque. Follow the hose/crimp sleeve manufacturerâs crimping specifications and general good-practice tightening-ensure even compression of the flat gasket, avoid over-tightening that could damage threads or gasket, and perform pressure testing to verify leak-free assembly. If a torque value is required, obtain it from the hose, gasket, or assembly equipment manufacturer.

Can the DKR-F hydraulic end, type ZBW140, AISI 304 steel be used with metric-threaded BSP adapters?

No. The DKR-F hydraulic end, type ZBW140, AISI 304 steel is specified with an internal BSP thread and nut, flat sealing that requires an additional flat gasket. It is designed for use with matching BSP-threaded fittings; using metric-threaded BSP adapters would create a mismatched thread interface, risking improper sealing, thread damage, and hydraulic failure. To ensure correct mechanical engagement and flat sealing with the required gasket, use adapters with the same BSP thread form and size as the DKR-F ZBW140.
