Does the AGR-F Hydraulic End ZBZ140, Carbon Steel require an additional flat gasket for proper sealing with the external BSP flat-thread connection?

Yes. The AGR-F Hydraulic End ZBZ140, Carbon Steel requires an additional flat gasket for proper sealing with the external BSP flat-thread connection. The product is designed with an external BSP thread that uses flat sealing, and the description specifies that optimal tightness is achieved by using an additional flat gasket (AGR-F).

Is the AGR-F Hydraulic End ZBZ140, Carbon Steel compatible with BSP flat-thread ports of different standards (e.g., BSPP vs BSPT) without modifying the fitting?

AGR-F Hydraulic End ZBZ140, Carbon Steel: No. The AGR-F Hydraulic End ZBZ140 uses an external BSP thread with flat sealing (BSPP-style flat face) and requires an additional flat gasket (AGR-F) to achieve proper sealing. BSPP (British Standard Parallel Pipe) flat-face ports and BSPT (British Standard Pipe Taper) threads are different standards: BSPP provides a parallel mating surface for a flat gasket seal, while BSPT relies on a tapered thread to achieve a metal-to-metal or sealant-assisted seal. Because the ZBZ140 is designed for flat-face BSPP-style sealing, it will not reliably seal against BSPT (tapered) ports without modifying the port or using an adapter. Attempting to connect ZBZ140 directly to BSPT risks leaks and improper mechanical engagement. To ensure compatibility without leak risk, use matching BSPP flat-face ports or an appropriate adapter designed to convert between BSPP flat-face and BSPT taper while preserving the required flat gasket seal.
