Does the DKR-F hydraulic end, type ZBW140 (carbon steel, Y) require a specific flat gasket thickness for proper sealing with internal BSP thread and nut?

DKR-F hydraulic end, type ZBW140, carbon steel, Y Format . with internal BSP thread and nut using flat sealing . does require an additional flat gasket (DKR-F) for proper sealing. The description specifies flat sealing, which depends on a gasket compressed between the mating face of the hydraulic end and the counterpart. While no exact gasket thickness is stated in the provided description, proper sealing typically requires a gasket thickness that allows sufficient compression to fill microâirregularities without preventing metalâtoâmetal contact where designed. Recommended approach: - Use the flat gasket type specified by the hose/end manufacturer (DKRâF matching part), as they determine the correct material and thickness for this specific fitting. - If manufacturer data is unavailable, select a gasket of standard thickness for BSP flat face fittings (commonly 1.5â2.5 mm for soft gaskets on lowâtoâmedium pressure hydraulic fittings) and verify by assembly: gasket must compress evenly, produce no visible gaps, and not extrude into the port. - Perform pressure testing after assembly to confirm leakâfree performance at the systemâs maximum working pressure. For guaranteed guidance, contact the manufacturer or supplier of the DKRâF hydraulic end, type ZBW140, carbon steel, Y Format for the exact gasket specification.

Is a specific torque value recommended when tightening the nut on the DKR-F hydraulic end, type ZBW140, carbon steel, Y to ensure flat gasket sealing?

No specific torque value is provided in the description for tightening the nut on the DKR-F hydraulic end, type ZBW140, carbon steel, Y. Proper sealing relies on using the correct flat gasket and correct assembly/crimping procedure with a compatible crimping sleeve for the hose type. For reliable flat gasket sealing, tighten the nut evenly to compress the gasket without deforming it; follow hose/crimping tool manufacturer recommendations or consult the supplier for any torque specification. If no supplier value is available, perform a controlled assembly check: tighten progressively while inspecting gasket seating and then pressure-test the assembly to verify leak-free performance.

Can the DKR-F hydraulic end, type ZBW140, carbon steel, Y be used with metric hoses and sleeves, or is BSP-only compatibility required?

DKR-F hydraulic end, type ZBW140, carbon steel, Y Format is designed with an internal BSP thread and nut and flat sealing that requires an additional flat gasket. It is intended for crimping into hydraulic and industrial hoses using a crimping sleeve appropriate for the hose type. That description does not mandate sleeve standard (metric vs BSP) for the crimping operation itself. the crimp sleeve must match the hose outer diameter and construction. However, the hydraulic endâs threaded connection is BSP (internal BSP thread), so the mating port or adapter must be BSP. In practice you can use metric-dimensioned hoses and corresponding metric crimp sleeves as long as the sleeve and hose are compatible with the ZBW140 fittingâs tail geometry and crimping specifications. But the threaded joint requires BSP; metric-threaded ports would need an adapter to connect to the BSP-threaded nut.
