CROSS

Copper Fitting Cross. It has four openings that can connect four pipes and is suitable for pipe systems with multi-directional connections. Copper has good electrical and thermal conductivity and strong corrosion resistance, making it suitable for water heating and refrigeration systems. The Cross design is very flexible in spatial layout and can be used for complex pipe layouts.There are usually a variety of sizes to choose from, such as 1/4 inch, 3/8 inch, 1/2 inch, etc., which are common in water heating and refrigeration systems. The installation method is usually through welding or crimping to ensure the sealing and strength of the connection. The four openings are all standard pipe diameters, which is convenient for use with other standard pipe fittings.The symmetrical design helps reduce the resistance of the fluid in the pipeline, improves system efficiency, and is more convenient during installation without special direction adjustment.

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.
