R-410A Adapter – Seamless Transition from 5/16" to 1/4" for Mini-Split Systems

Our company’s R-410A Adapter is the perfect solution for HVAC professionals working with mini-split and ductless systems. This adapter converts a 5/16" SAE female port (commonly found in R-410A systems) to a 1/4" SAE male connection, allowing standard charging hoses and manifold gauges to be used safely and efficiently.

Brass Construction, Built to Last
Manufactured using precision-machined forged brass, this adapter ensures corrosion resistance, high pressure endurance, and reliable leak-free sealing in harsh field conditions.

Threading & Compatibility

• 5/16" SAE Female (Quick Coupler) side connects directly to R-410A mini-split service ports.

• 1/4" SAE Male Flare side allows compatibility with standard hose fittings, making it easy to charge, vacuum, or test pressure.

Built-in Valve Core Depressor
The integrated depressor pin ensures automatic opening of Schrader valve cores — enabling smooth refrigerant flow without manual pin adjustments.

Compact & Convenient
Designed for service professionals, the straight-line build allows access to tight spots in HVAC installations, saving time and hassle.
