R134 A/C Standard Imperial Interface – 2 Pcs Quick Coupler Adapter Set
The R134 A/C Quick Coupler Adapter set is an essential tool for technicians and DIY users working on household air conditioning systems. Designed to fit standard R134A refrigerant ports, these couplers feature an imperial interface and are ideal for charging, evacuation, and diagnostic servicing of air conditioners. Each set includes two precision-engineered couplers—one high-pressure (red) and one low-pressure (blue)—ensuring a secure and leak-free connection to the AC system.
Crafted from durable, corrosion-resistant materials, these adapters are built to withstand repeated use in demanding repair environments. Their quick-connect functionality saves time and ensures safety during servicing, making them a valuable addition to any toolkit.
While primarily used for AC maintenance, these couplers can also be used in compatible systems in garages, workshops, and even greenhouse climate-control systems, offering flexibility beyond traditional HVAC repair.
