The ME Series REF Joints are precision-engineered copper branch piping kits, designed to accurately and reliably divide refrigerant flow in VRF systems operating with R410A refrigerant. Each complete set includes matching liquid and suction tee joints with pre-assembled reducers, engineered for a perfect, secure fit right out of the box
This pre-configured system minimizes on-site brazing, drastically reducing installation time and the risk of leaks or contamination. Manufactured from top-grade copper and featuring high-quality XLPE or ArmaFlex® insulation, the ME Series ensures optimal thermal stability, prevents condensation, and delivers robust, durable performance for the life of your HVAC system.
