1/4″ SAE x 5/16″ SAE Adapter Fitting

Precision brass adapter fitting, designed for quick conversion between standard 1/4″ SAE (7/16″-20 UNF) and 5/16″ SAE (1/2″-20 UNF) connections. Essential for refrigeration technicians and HVAC installers, it allows standard 1/4″ equipment (traditional pressure gauges, vacuum pumps, scales, and charging hoses) to be connected to the service valves of air conditioners and systems operating with R410A refrigerant.

Strengths

• R410A Compatibility: Allows for the direct use of pressure gauges and hoses with a standard 1/4″ SAE connection on the standard 5/16″ service ports of R410A air conditioners.

• Integrated Depressor: An internal valve press calibrated to open the Schrader valve pin, minimizing refrigerant leaks during connection.

• High-Pressure Resistance: Sturdy forged brass construction, ideal for withstanding the high operating pressures typical of direct expansion systems.

Recommendation for use: Check the condition of the inner gasket regularly to ensure a perfect vacuum seal and prevent leaks during charging.
