Adapter for 40L Cylinder Faucet | Right-Hand Thread W 21.7 x 1/14″ DX Female to 5/16″ SAE Male

Reducing fitting with standard right-hand thread (DX), 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) 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.

Strengths

• 5/16″ Direct Connection: Allows for the immediate connection of R410A hoses (5/16″ SAE) to 40-liter industrial cylinders.

• Standard Right-Hand Thread (DX): Fully compatible with standard valves for non-flammable refrigerants.

• Zero Leaks: Precision machining ensures maximum sealing performance at high operating pressures (e.g., R410A).

Safety Warning: This fitting has a right-hand thread (DX) and is intended for Class A1 (non-flammable) refrigerant gases. It is not suitable for cylinders containing flammable or mildly flammable A2L gases (e.g., R32, R1234yf, hydrocarbons), which require a left-hand thread (SX).
