Does the DKR-F 45Â° hydraulic end, type ZBW340, carbon steel require a specific flat gasket material or thickness for proper sealing with internal BSP thread and nut?

Yes. The DKR-F 45Â° hydraulic end, type ZBW340, carbon steel with internal BSP thread and nut requires an additional flat gasket (DKR-F) for proper flat sealing. The fitting description specifies flat sealing and explicitly notes the use of an additional flat gasket; no integrated seal is provided. Use a gasket material compatible with carbon steel and hydraulic fluids (common choices: NBR (nitrile), PTFE, or metal-backed gaskets depending on pressure, temperature and fluid). Thickness and specific material should match the BSP flat-face sealing requirements and the nut/port dimensions . typically a thin flat gasket (0.5â2.0 mm range) suitable for BSP flat connections is used, but exact thickness and material must be confirmed from the hose/fitting manufacturer or the portâs dimensional spec to ensure correct crush and sealing for the operating pressure and fluid.

Is the DKR-F 45Â° hydraulic end, type ZBW340, carbon steel compatible with standard BSP flat gaskets or does it need a specific gasket size?

The DKR-F 45Â° hydraulic end, type ZBW340, carbon steel requires an additional flat gasket for its flat sealing BSP connection. It uses a flat sealing face with internal BSP thread and nut, so you must fit a flat (BSP) gasket. Use a gasket sized to match the specific BSP thread and sealing face of the ZBW340-standard BSP flat gaskets may fit if they match the exact BSP thread size and face dimensions; if unsure, verify the BSP thread size of the fitting and select a matching flat gasket for proper sealing.

Can DKR-F 45Â° hydraulic end, type ZBW340, carbon steel be used with reusable flat gaskets or only single-use ones?

DKR-F 45Â° hydraulic end, type ZBW340, carbon steel Format uses flat sealing and explicitly requires an additional flat gasket (DKR-F). Whether a reusable flat gasket can be used depends on the gasket design and manufacturer recommendations: flat metal or metal-backed gaskets are often reusable only if undamaged and if the sealing faces remain perfect; soft (rubber, cork, PTFE) or crushable flat gaskets are typically single-use because they deform to form the seal and will not reliably reseal after removal. Given the fittingâs carbon steel, galvanized construction and its specification for a flat gasket, you should follow these rules: - Use the gasket type specified by the fitting/hose manufacturer (preferred). They will state if a reusable gasket is acceptable. - If the supplied or specified gasket is a crushable or elastomeric flat gasket, treat it as single-use. - If a metallic or reusable-rated flat gasket is specified and shows no damage, it may be reused, but only if torque and sealing surfaces are inspected and comply with reassembly specs. - For critical hydraulic applications, best practice is to replace flat gaskets on reassembly to ensure leak-free performance and safety. If you donât have manufacturer guidance for DKR-F 45Â° hydraulic end, type ZBW340, carbon steel Format, assume single-use flat gaskets unless you can confirm the gasket material and reuse rating.
