Reducing fitting with standard right-hand thread (DX)<\/b>, designed to connect 40-liter cylinders of non-flammable gases (Class A1, such as R410A, R404A, R134a, R407C) directly to recharge hoses and pressure gauges with a 5\/16″ SAE (1\/2″-20 UNF)<\/b> connection. Made of high-quality solid brass, it eliminates the need for multiple adapters, ensuring a direct, safe, and hermetically sealed connection that prevents refrigerant leaks.<\/p>\n

Strengths<\/b><\/p>\n

    \n
  • \n

    5\/16″ Direct Connection:<\/b> Allows for the immediate connection of R410A hoses (5\/16″ SAE) to 40-liter industrial cylinders.<\/p>\n<\/li>\n

  • \n

    Standard Right-Hand Thread (DX):<\/b> Fully compatible with standard valves for non-flammable refrigerants.<\/p>\n<\/li>\n

  • \n

    Zero Leaks:<\/b> Precision machining ensures maximum sealing performance at high operating pressures (e.g., R410A).<\/p>\n<\/li>\n<\/ul>\n
