CO2 Copper Fittings
NDL’s CO2 copper fittings, made from C19400 high-pressure copper, are specifically engineered to meet the rigorous demands of CO2 refrigeration and HVAC systems. These fittings combine advanced material science with precision design to deliver exceptional performance in high-pressure environments.
Design and Features
- Exceeding Design Expectations
Our high-pressure copper-iron alloy fittings undergo burst pressure testing, consistently achieving results exceeding 3 times the design pressure. This exceptional strength ensures reliability in the most challenging applications, giving contractors and designers peace of mind. - Enhanced Strength Material
Made from a durable copper-iron alloy, the fittings offer added strength and long-term resilience. This robust material ensures reliable performance and extends the lifespan of refrigeration and HVAC systems. - High-pressure Reliability
With a secure and long-lasting design, these fittings are ideal for high-pressure applications like transcritical CO2 systems. Their reliability minimizes the risk of leaks, boosting safety and efficiency. - Stronger Joint Integrity
The fittings’ tight cup-side tolerances create stronger joints with tubing and simplify brazing. This precision reduces installation effort and ensures a secure, efficient connection. - Easily Identifiable
Each fitting is marked with “CO2 130 BAR” and its OD size, allowing for quick and accurate identification during installation or in the field. - Clean Packaging
Every fitting is poly-bagged to stay clean and contaminant-free before installation. This helps maintain system integrity while simplifying inventory management, as contractors can count boxes instead of individual fittings.
