Is the ISO-A hydraulic quick connector plug with GW BSP with valve, DRAGON, type IA suitable for agricultural hydraulic oil systems up to 350â¯bar?

Yes. The ISO-A hydraulic quick connector plug with GW BSP with valve, DRAGON, type IA is suitable for agricultural hydraulic oil systems up to 350 bar, provided you select the correct coupling size (working pressure depends on size). It is designed for power hydraulics and agricultural machinery, uses NBR seals compatible with hydraulic oil, is made of galvanized steel, rated for -20Â°C to +100Â°C, has a 4:1 safety factor, and flow ratings are given at a 3 bar pressure drop. Ensure the specific size/version you choose is the one rated to 350 bar.

Can the ISO-A hydraulic quick connector plug with GW BSP with valve, DRAGON, type IA be used with NBR seals at temperatures below -20Â°C?

No. ISO-A hydraulic quick connector plug with GW BSP with valve, DRAGON, type IA uses NBR seals with an operating temperature range from â20 Â°C to +100 Â°C. Below â20 Â°C NBR loses elasticity, becomes brittle and may leak or fail under pressure, so it is not suitable for reliable service at temperatures under â20 Â°C. For applications below â20 Â°C select a coupling with low-temperature compatible seals (e.g. FKM, HNBR rated for lower temperatures, or specialty lowâtemperature elastomers) and confirm compatibility with hydraulic oil and pressure requirements.

Q: Is the ISO-A hydraulic quick connector plug with GW BSP with valve, DRAGON, type IA compatible with other manufacturersâ ISO-A (euro) couplings?

Yes . the ISO-A hydraulic quick connector plug with GW BSP with valve, DRAGON, type IA is compatible with other manufacturersâ ISO-A (euro) couplings. The product is described as an ISO-A hydraulic quick coupling with shut-off valve and internal BSP thread, intended for power hydraulics and commonly used in agricultural machinery. It is explicitly noted as interchangeable with ISO-A quick couplings from other manufacturers, meaning it follows the ISO-A (euro) dimensional and performance standards. Materials and seals (galvanized steel, NBR), operating temperature (-20Â°C to +100Â°C), working pressure (up to 350 bar depending on size), safety factor 4:1, and flow rating at a 3 bar pressure drop align with typical ISO-A specifications, supporting interchangeability.
