Adapter for 40L Cylinder Valve | W 21.7 x 1/14″ Female Thread to 1/4″ SAE Male Thread

High-precision reducer fitting designed to connect standard 40-liter cylinder valves with a W 21.7 x 1/14″ connection to piping and pressure gauge assemblies with a standard 1/4″ SAE connection. Made of high-quality solid brass, it ensures a reliable, airtight seal and prevents gas leaks during charging, transfer, and maintenance operations on HVAC/R systems.

Strengths

• Perfect airtight seal: Precision machining to prevent refrigerant leaks.

• Maximum durability: Sturdy construction resistant to high operating pressures and wear from continuous tightening.

• Universal compatibility: Ideal for connecting standard 1/4″ SAE hoses to large-capacity industrial cylinders (40L).

Recommendation: Before tightening, always check that the internal seal is intact to ensure maximum safety at high pressures.
