Is the ISO 6150B Quick Coupling Plug with Hose Tail, GROMELLE DN 5.5 compatible with standard 6 mm pneumatic hoses and fittings?

ISO 6150B Quick Coupling Plug with Hose Tail, GROMELLE DN 5.5 is not fully compatible with standard 6 mm pneumatic hoses and fittings without checking the exact inner/outer diameters and thread/connection type. DN 5.5 indicates a nominal diameter close to 5.5 mm, and the hose tail is sized for that diameter, so a 6 mm hose may be a close fit but could be either slightly loose or tight depending on the hose wall thickness. The coupling supports working pressures up to 16 bar and offers high flow (700 l/min at 6 bar), so performance is suitable for typical 6 mm hose applications if a proper seal is ensured. Recommendation: verify the hose's inner diameter and outer diameter at the barbed end and confirm the hose tail dimensions or use a compatible adapter/clamp to ensure a secure, leak-free connection.

Can the ISO 6150B Quick Coupling Plug with Hose Tail, GROMELLE DN 5.5 be used safely in compressed air systems operating at temperatures below -20°C or above +100°C?

No. The ISO 6150B Quick Coupling Plug with Hose Tail, GROMELLE DN 5.5 is specified for reliable operation within the temperature range of −20°C to +100°C. Using it below −20°C or above +100°C would exceed the manufacturer's stated limits and could compromise materials, sealing performance and safe operation in compressed air systems. For applications outside this range, select a coupling rated for those temperatures or consult the manufacturer for suitable alternatives.
