Is the ISO-A Hydraulic Bulkhead Socket, Metric GZ, Valve, Push Pull, Type IA compatible with other ISO-A quick couplings from different manufacturers?

Yes — the ISO-A Hydraulic Bulkhead Socket, Metric GZ, Valve, Push Pull, Type IA is fully interchangeable with ISO-A quick couplings from other manufacturers. Designed to the ISO-A (euro coupling) standard, it ensures cross-brand compatibility and flexible integration across hydraulic systems. Its push–pull mechanism provides automatic disconnection under accidental hose tension, and the internal shut-off valve prevents fluid loss. Constructed from galvanized steel with NBR seals, it operates reliably from −25°C to +100°C at up to 250 bar, with a 4:1 safety factor and optimized flow characteristics (measured at a 3 bar pressure drop), making it suitable for demanding agricultural and industrial applications.

Can the ISO-A Hydraulic Bulkhead Socket, Metric GZ, Valve, Push Pull, Type IA be used with biodegradable hydraulic oils or other non-mineral fluids?

The ISO-A Hydraulic Bulkhead Socket, Metric GZ, Valve, Push Pull, Type IA is specified and engineered for use with hydraulic oil and features NBR (nitrile) seals. NBR is compatible with many mineral hydraulic oils but has limited compatibility with some biodegradable and non-mineral fluids (e.g., certain esters, polyalkylene glycols, phosphate esters) which can cause swelling, hardening or accelerated wear of NBR seals. Therefore: - If the biodegradable or non-mineral fluid's compatibility with NBR is confirmed (manufacturer data sheet or compatibility chart showing NBR safe), the coupling may be used. - If the fluid is an ester-based, PAG or other synthetic type without proven NBR compatibility, do not assume compatibility — seals may degrade and compromise performance and safety. Recommendation: Verify the specific fluid’s compatibility with NBR seals (or request alternative seal materials from the supplier, such as FKM/Viton or EPDM, if available) and confirm suitability with the coupling manufacturer before use.
