Do I need to use the DKR-F Hydraulic End ZBW140, Carbon Steel flat gasket for proper sealing when installing Hydraulic End Z?

Yes. The standard Hydraulic End Z requires an additional flat gasket for proper sealing. Use the DKR-F Hydraulic End ZBW140, Carbon Steel flat gasket to ensure tightness and long-term durability of the internal BSP thread with nut and flat sealing. The gasket guarantees leak-free performance under demanding conditions and complements the carbon steel, zinc-coated fitting to provide a secure, corrosion-resistant connection when crimped with the correct sleeve for the hose type.

Can I use an alternative flat gasket instead of the DKR-F Hydraulic End ZBW140, Carbon Steel without compromising sealing and safety?

Short answer: No — you should not substitute an alternative flat gasket for the DKR-F Hydraulic End ZBW140, Carbon Steel without careful verification, because doing so can compromise sealing integrity and safety. Why: The Z-type hydraulic end is engineered to work with the DKR-F flat gasket to achieve the correct compression, material compatibility, and sealing geometry under hydraulic pressures and mechanical loads. The specified DKR-F ensures tightness and durability even in demanding conditions and is matched to the internal BSP thread, nut, and crimp sleeve assembly. Using an unapproved or different gasket risks improper sealing, leakage, accelerated wear, corrosion issues, and potential system failure or safety hazards. When substitution may be acceptable: Only if the alternative gasket is an exact match in dimensions, durometer (hardness), material (chemical and temperature compatibility with hydraulic fluid and carbon steel/zinc coating), and is certified by the manufacturer or by a qualified engineer for the ZBW140 assembly and operating conditions (pressure, temperature, dynamic loads). Recommended action: Use the specified DKR-F Hydraulic End ZBW140, Carbon Steel Format whenever possible. If you must consider an alternative, obtain manufacturer approval or a written engineering assessment confirming equivalence for sealing performance and safety under your application’s conditions.
