Question by: Ralph T on Oct 1, 2025, 7:35 AM
Will this plug work with standard quick disconnect fittings?
Answer by: Customer Support on Oct 3, 2025, 8:27 AM
This plug is compliant with US Industrial Interchange and A-A-59439 standards, so it should work with any fitting that meets those same standards. It's also ISO 6150 Series B certified.
Question by: Harvey A on Dec 30, 2025, 6:26 AM
does this plug work down to negative 40 degrees or is that just for the coupler half
Answer by: Customer Support on Jan 1, 2026, 6:52 AM
The plug itself is rated down to -40 degrees, so that cold temperature rating applies to this component. Carbon steel construction and Buna-N seals handle that range without issue, making it a solid choice for outdoor or cold-storage hydraulic setups where temperatures really bottom out.
