Mueller Streamline a 18960 Refrigeration Ball Valve 3/8 in

Product Description

The MUELLER STREAMLINE a 18960 is a 3/8-inch pressure-rated refrigeration ball valve designed for use in refrigerant line applications. Built to the CycleMaster standard, this valve carries a maximum allowable pressure (MAP) rating of 775 psi, making it suitable for high-pressure refrigerant systems. It features FTG (fitting) end connections and a flow coefficient (Cv) of 4.00. Licensed HVAC and refrigeration technicians install this valve as part of system service, isolation, or line-set assembly work. The operating temperature range of -40 degrees F to 300 degrees F covers the full spectrum of commercial and residential refrigerant applications.

This valve is used in residential and commercial refrigeration and air conditioning systems where a reliable, pressure-rated shutoff or service valve is required. The 3/8-inch connection size is common in refrigerant suction and liquid line configurations. It is appropriate for new installations and retrofit service work on systems using modern refrigerants. HVAC-R technicians and refrigeration mechanics are the primary installers of this component.

Key Features

• Maximum allowable pressure of 775 psi for high-pressure refrigerant service
• 3/8-inch FTG end connections for standard sweat or press-fit installation
• Cv of 4.00 for predictable flow performance
• Operating temperature range: -40 degrees F to 300 degrees F
• CycleMaster pressure-rated design built for repeated open/close cycling
• Compatible with seal cap kit A 17842 for field servicing

Compatibility

Designed as an OEM-style replacement or new-installation refrigeration ball valve for systems requiring a 3/8-inch FTG pressure-rated shutoff valve in refrigerant line service.

Installation Notes

Installation should be performed by a licensed HVAC-R technician or refrigeration mechanic. Recover all system refrigerant and confirm system pressure is at zero before cutting into any refrigerant line. Follow applicable EPA Section 608 requirements for refrigerant handling. Use appropriate brazing or press-fit tools per the end-connection type and consult local mechanical codes for inspection requirements.
