1. Product Description
COPPER FITTING CROSS is designed for four-way fluid diversion or confluence in pipeline systems. It supports multi-pipe cross-connection and is suitable for complex scenarios such as water heating, refrigeration, and industrial pipelines to achieve efficient fluid transmission and flexible layout.

2. Product Features
High-purity copper material: Made of high-quality copper, it has excellent corrosion resistance, thermal conductivity and ductility, supports welding and brazing processes, and ensures long-term stable use.
Four-way interconnection design: The cross structure provides four equal-diameter or variable-diameter interfaces to meet the needs of multi-pipe cross-connection, simplify system complexity, and save installation space.
High sealing performance: The socket connection is combined with the welding process to eliminate the risk of interface leakage and adapt to medium and low pressure fluid transmission environments.
Multi-function compatibility: Suitable for cold water, hot water, gas and non-corrosive liquid media, compatible with various pipeline systems.
