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

Yes. The ISO-A Hydraulic Quick Coupler Socket, Metric GZ, Valve, Push-Pull, Type IA is fully interchangeable with ISO-A (Euro) couplings from other manufacturers. Designed to the ISO-A standard, it uses the common push-pull mechanism and metric external thread, ensuring mechanical and functional compatibility across brands. Its galvanized steel construction, NBR seal, 250 bar working pressure, 4:1 safety factor and -25°C to +100°C temperature range mean it will reliably mate with other ISO-A components in agricultural and industrial hydraulic oil systems while maintaining safe, leak-free performance.

Can the ISO-A Hydraulic Quick Coupler Socket, Metric GZ, Valve, Push-Pull, Type IA be used safely in agricultural equipment operating below -25°C or above +100°C?

No. The ISO-A Hydraulic Quick Coupler Socket, Metric GZ, Valve, Push-Pull, Type IA is specified for an operating temperature range of -25°C to +100°C. Using it below -25°C or above +100°C would place the coupling and its NBR seals outside their rated limits, risking seal hardening, leakage, loss of sealing integrity, material embrittlement or accelerated wear of galvanized steel, and possible malfunction of the push-pull valve mechanism. For safe operation outside the specified range, consult the manufacturer for alternative materials/seals (e.g., FKM/EPDM) or a coupling rated for the required temperatures.
