Is the ISO-A Hydraulic Bulkhead Socket with Valve, Metric GZ, DRAGON IA compatible with other manufacturers' ISO-A euro couplings?

Yes. The ISO-A Hydraulic Bulkhead Socket with Valve, Metric GZ, DRAGON IA is fully compatible with ISO-A (euro) quick couplings from other manufacturers. It is designed for full interchangeability, uses standard ISO-A dimensions and sealing (NBR), and meets common hydraulic requirements (working pressure up to 250 bar, -20°C to +100°C). Manufactured from galvanized steel for durability and corrosion resistance, it will integrate smoothly into existing ISO-A euro coupling systems.

Can the ISO-A Hydraulic Bulkhead Socket with Valve, Metric GZ, DRAGON IA be used with hydraulic systems operating at temperatures below -20°C or above +100°C?

The ISO-A Hydraulic Bulkhead Socket with Valve, Metric GZ, DRAGON IA is specified to operate in a temperature range from −20°C to +100°C. Using it below −20°C or above +100°C is outside the manufacturer's stated operating limits and is not recommended. Operating beyond these temperatures may compromise the NBR seals (leading to hardening, cracking or loss of elasticity at low temperatures and swelling or softening at high temperatures), reduce material performance of the galvanized steel components, and jeopardize pressure ratings and leak-free operation. If your application requires service outside −20°C to +100°C, consult the manufacturer or supplier for alternative sealing materials (e.g., FKM/Viton or EPDM) or specially rated couplings designed for extreme temperatures, and perform appropriate testing or validation before use.
