Does the AGR-F hydraulic end, type ZBZ140 (carbon steel) require a specific flat gasket size for proper flat sealing with BSP external thread?

Yes. The AGR-F hydraulic end, type ZBZ140, carbon steel (with external BSP thread and flat sealing) requires a specific flat gasket for proper flat sealing. The product description explicitly states that flat sealing ârequires the use of an additional flat gasket (AGR-F).â For reliable, leak-free sealing you must use a flat gasket sized to match the BSP external thread seat and the AGR-F end face dimensions. Using the correct gasket material and exact seat diameter/thickness specified for ZBZ140 ensures proper compression, sealing performance, and longevity when crimped into hydraulic hose assemblies. If you need the exact gasket dimensions, refer to the manufacturerâs technical drawing or part specification for AGR-F hydraulic end, type ZBZ140, carbon steel.

Is a specific flat gasket thickness required for the AGR-F hydraulic end, type ZBZ140, carbon steel to ensure proper flat sealing with BSP external thread?

For the AGR-F hydraulic end, type ZBZ140, carbon steel, no single universal flat gasket thickness is specified in the provided description. The fitting requires an additional flat gasket for proper flat sealing with the BSP external thread, but the correct gasket thickness depends on the mating port geometry, surface finish, and compression provided by the assembly. Use a gasket material and thickness that achieve full contact and compression without over-compression or gaps-commonly thin metallic or reinforced flat gaskets selected to match the BSP thread face and flange dimensions. Confirm final gasket choice and thickness with the hose/fitting manufacturer or by testing under assembly torque and pressure conditions to ensure leak-free sealing.

Which flat gasket material is recommended for AGR-F hydraulic end, type ZBZ140, carbon steel, with BSP external thread?

For AGR-F hydraulic end, type ZBZ140, carbon steel with BSP external thread (flat sealing), the recommended flat gasket material is NBR (Nitrile Rubber) with a steel-reinforced washer or a bonded metal-reinforced elastomeric gasket. NBR offers excellent resistance to hydraulic oils, good sealing under compression, and suitable temperature range for typical hydraulic and industrial hose applications. If higher temperature or better chemical resistance is required, consider Viton (FKM) bonded to a metal washer. For standard hydraulic service, choose NBR bonded to a thin steel or copper washer sized to match the flat sealing face of the AGR-F hydraulic end, type ZBZ140, carbon steel.
