Standard R134a Gas Quick Adapters Kit Coupler Male Fittings

Material: Brass body, stainless steel spring, NBR seal ring

Interface type: metric thread (e.g. G 1/4″, G 1/2″, etc.)

Working pressure: up to 4.0MPa

Operating temperature: -30°C to 120°C

Applicable refrigerant: R134a, R404A, R410A, R1234yf, and R22

High Efficiency and Convenience：Achieves plug-and-play within seconds without the need for tools. It enables quick switching between maintenance equipment and streamlines processes such as refrigerant charging and leakage detection.

Safety and Reliability：Dual-seal design ensures zero leakage. The check valve prevents backflow, and high-pressure models are equipped with a pressure relief function.

Precise Adaptability：Dedicated interfaces for different refrigerants, distinguished by color and shape, completely eliminate incorrect connections. It is compatible with equipment from multiple brands.

Durability and Cost-effectiveness：Made of corrosion-resistant brass or stainless steel, with fluororubber seals that resist aging. It offers a long service life and requires minimal maintenance.

Versatility：Suitable for a wide range of scenarios, including household appliances, automotive, and industrial refrigeration systems. Some models integrate functions such as pressure display.

Quick couplings play a vital role in refrigeration systems. They are used to connect and disconnect refrigerant lines, such as in the installation, repair and maintenance of air conditioners, refrigerators, freezers, automotive air conditioners and industrial refrigeration equipment. Thanks to its fast connect and disconnect characteristics, quick couplings can significantly reduce system downtime and increase work efficiency.

Body: Brass, because of its good mechanical properties and corrosion resistance, is the ideal material for the manufacture of quick joints.

Spring: Stainless steel, provides excellent elasticity and durability, ensuring that the joint will maintain good performance after many connections and disconnections.

Seal ring: NBR (nitrile butadiene rubber), suitable for most refrigerants and working environments due to its good oil and temperature resistance.
