Designed for today’s high-efficiency air conditioning and heat pump equipment, this manifold provides precise pressure readings for charging, evacuation, diagnostics, and system troubleshooting.

Built with a forged brass body for long-lasting durability, the Series 41 manifold features sliding double O-ring pistons that reduce wear and ensure smooth valve operation over time. Long-life nylon seats provide dependable sealing, while full porting maximizes refrigerant flow capacity for faster and more efficient service.

The hose assemblies are UL recognized and rated for 4000 psi (275 bar) burst pressure and 800 psi (55 bar) working pressure (File #SA9737), making this gauge set suitable for high-pressure refrigerants and demanding service conditions.
