1/2-20 UNF-F X 1/4 FL-M CONN - Mastercool

The Mastercool 90363 connector is a precision-engineered adapter designed for professional automotive and industrial applications. This robust fitting facilitates the connection between systems utilizing a 1/2-20 UNF female thread and those requiring a 1/4-inch male flare connection, providing a secure and leak-free interface. It is an essential component for technicians working with various fluid and gas handling systems where reliable transitions are critical.

Key Features

• Precision Machining: Manufactured to exact specifications for a perfect fit and consistent performance.
• Durable Construction: Built from high-quality materials to withstand the rigorous demands of professional environments and frequent use.
• Versatile Connection: Features a 1/2-20 UNF (Unified National Fine) female thread on one end and a 1/4-inch male flare connection on the other.
• Leak-Resistant Design: Engineered to create tight seals, minimizing the risk of leaks in critical applications.
• Professional Grade: Designed for longevity and reliability, meeting the standards required by professional mechanics and industrial technicians.

Applications

The Mastercool 90363 connector is ideal for a range of professional tasks, particularly in automotive air conditioning, refrigeration, and hydraulic systems. It can be used to connect pressure gauges, charging hoses, vacuum pumps, and recovery units to various service ports or system components. Common use cases include adapting older R12 AC service ports (which often use 1/2-20 UNF threads) to modern R134a or general HVAC equipment that typically uses 1/4-inch flare fittings. This connector ensures compatibility and efficient operation during diagnostics, charging, and maintenance procedures.
