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

Yes. The AGR-F hydraulic end, type ZBZ140, carbon steel, zinc-nickel, with an external BSP thread and flat sealing is designed to require an additional flat gasket for proper BSP external thread flat sealing. Use a flat gasket sized to match the BSP thread diameter and the sealing face dimensions of the AGR-F fitting (commonly matching BSPP/BSP threads such as 1/4", 3/8", 1/2" etc.), ensuring the gasket material is compatible with hydraulic fluid and the zinc-nickel coated steel. For reliable sealing, select a flat gasket whose inner diameter clears the thread bore, outer diameter covers the seating face, and thickness/compression properties suit the application. If available, refer to the manufacturerâs specification or the hose/fitting datasheet for the exact gasket inner/outer diameter and thickness for the specific BSP size of the AGR-F hydraulic end, type ZBZ140, carbon steel, zinc-nickel.

Can AGR-F hydraulic end, type ZBZ140, carbon steel, zinc-nickel, be used with standard BSP flat gaskets or does it need a special gasket?

AGR-F hydraulic end, type ZBZ140, carbon steel, zinc-nickel, requires a flat gasket for sealing the external BSP flat thread. It is designed for flat sealing and specifically states the need for an additional flat gasket (AGR-F). Therefore you must use a flat gasket compatible with BSP flat-face connections; standard BSP flat gaskets that match the size and pressure rating may be used, but confirm correct dimensions and material compatibility for your application.

Is a specific flat gasket size required for AGR-F hydraulic end, type ZBZ140, carbon steel, zinc-nickel?

Yes. AGR-F hydraulic end, type ZBZ140, carbon steel, zinc-nickel requires a specific flat gasket for proper flat sealing on the external BSP thread. The product description explicitly states that flat sealing "requires the use of an additional flat gasket (AGR-F)." To ensure leak-free performance, the gasket must match the AGR-F dimensions and material compatibility for the BSP male thread and the sealing face of the ZBZ140 fitting. Use a gasket sized for the exact BSP thread diameter and pressure rating of the hose assembly, made from a compatible material for hydraulic oil and the zinc-nickel plated carbon steel surface. If in doubt, confirm the exact flat gasket size with the manufacturer or supplier, quoting AGR-F hydraulic end, type ZBZ140, carbon steel, zinc-nickel.
