HVAC Copper Cross – 4-Way Equal & Reducing for Refrigeration,C12200 wrot copper, ASME B16.22 compliant. C x C x C x C sweat-end design for 4-way connections. Sizes 1/4″ to 2-5/8″ OD. Equal and reducing configurations. Max pressure 700 psi. Leak-proof, corrosion resistant.
Our Copper Cross is a precision-engineered wrot copper fitting designed to connect four lengths of copper tubing at a 90-degree branch angle in air conditioning, refrigeration, and heat pump systems. Manufactured from high-purity C12200 phosphorus-deoxidized copper, it provides a secure, leak-proof junction for 4-way connections in refrigerant circuits.
The cross features a sweat-end (C x C x C x C) design with precision-machined cup connections, ensuring a consistent capillary gap for reliable brazing with Sil-Fos or comparable alloys. The seamless, one-piece wrot construction eliminates weld seams, reducing potential leak points in high-pressure refrigerant circuits. Available in equal and reducing configurations to accommodate different branch line sizes.
