R410A quick coupler adapter for mini split HVAC systems

Air conditioner charging port adapter – R410A HVAC,Converts 5/16″ SAE charging/vacuum ports to accept 1/4″ SAE gauge hose sets. Brass construction with swivel tip. PTFE/rubber gaskets prevent leaks. 45° angled and straight options.

R410A Quick Coupler Adapter – 5/16″ Female to 1/4″ Male Flare

Our R410A Quick Coupler Adapter converts 5/16″ SAE charging and vacuum ports on mini split systems to accept standard 1/4″ SAE gauge hose sets. It solves the compatibility problem between newer R410A equipment and older manifold gauge sets, enabling refrigerant charging, evacuation, and pressure testing without replacing existing tools.

Made of heavy-duty brass with a full swivel tip for easy access in tight spaces. Deeply knurled coupler nuts allow finger-tightening. Available with PTFE and rubber gaskets to ensure a leak-free seal.
