The Johnson Controls SEC99AA-36 is a professional-grade UltraCap Armored Capillary assembly designed for high-pressure refrigeration monitoring and control applications. Engineered for durability, this 36-inch armored capillary tube features a 0.06" internal diameter and is terminated with 1/4" SAE female flare fittings on both ends. This specific configuration includes straight fitting angles with integrated valve depressors, ensuring seamless integration with standard service valves and pressure switches. As a direct equivalent to the SEC99AA-36C, this component provides reliable vibration dampening and pressure equalization in demanding HVACR environments. The stainless steel armor protects the internal copper capillary from mechanical damage and work-hardening failures, making it a standard choice for refrigeration pressure control lines where system uptime is critical. Contractors utilizing Johnson Controls refrigeration parts will find this assembly compatible with a wide range of non-corrosive refrigerants, providing a robust solution for connecting pressure transducers or mechanical controls to the main refrigerant circuit. Key Benefits for Technicians Vibration Resistance: The armored design mitigates the risk of fracture caused by compressor harmonics and thermal expansion. Internal Valve Depressors: Both straight fittings include depressors to allow for pressure readings without removing the core. Universal Compatibility: The 1/4" SAE flare connection fits standard access ports on commercial refrigeration racks and AC units. Precision Bore: A 0.06" I.D. ensures accurate pressure signal transmission with minimal refrigerant volume. Interchangeability: Fully compatible and identical in specification to the SEC99AA-36C model. Common Questions & Technical Insights Is the SEC99AA-36 compatible with all common synthetic oils? Yes, the materials used in the UltraCap Armored Capillary are compatible with most standard and synthetic refrigeration lubricants, provided the refrigerant itself is non-corrosive. What is the primary difference between the SEC99AA-36 and the SEC99AA-36C? Technically, there is no performance difference; the SEC99AA-36 and SEC99AA-36C are identical in length, fitting type, and internal diameter. Does this capillary assembly include the necessary gaskets? These female flare fittings rely on a metal-to-metal seal or standard copper crush washers/gaskets depending on the specific application requirements on the job site.
