The Johnson Controls SEC99AA-24 UltraCap Armored Capillary is a 24-inch pressure connection engineered for high-demand refrigeration and air conditioning applications. Featuring a 1/4" SAE female flare on both ends, this 0.06" internal diameter capillary is fully compatible with all common non-corrosive refrigerants. It utilizes a 1/8" OD copper tube protected by a durable brass armor sleeve, which provides essential resistance against abrasion and fatigue in high-vibration environments. Both ends are configured with straight fittings and include integral Schrader valve depressors to ensure seamless interaction with service ports. Rated for a maximum working pressure of 690 psig (4,757 kPa) and an operating temperature range of -50?F to 350?F, the SEC99AA-24 armored capillary (identical to SEC99AA-24C) is a reliable solution for connecting pressure-actuated controls, such as those in the PENN line, while effectively minimizing pressure pulsations through its small-orifice design. Professionals rely on this refrigerant pressure line for its leak-proof construction and rugged field performance. Key Benefits for Technicians: Vibration Resistance: The brass armor sleeve shields the copper tube from abrasion and mechanical stress caused by compressor vibration. Pulsation Dampening: The 0.06" small orifice naturally reduces pressure fluctuations to protect sensitive control components. Universal Compatibility: Designed for use with all standard non-corrosive refrigerants and 1/4" SAE male flare connections. Zero Effusion: Internal copper construction ensures refrigerant stays contained without environmental leakage. Flexible Installation: 24-inch length allows for proper coiling and anchoring to maintain system integrity. Common Questions & Technical Support: Is the SEC99AA-24 compatible with high-pressure CO2 systems? This model is rated for common non-corrosive refrigerants with a maximum working pressure of 690 psig. It is not recommended for high-pressure R-744 (CO2) applications exceeding this limit. What is the difference between the SEC99AA-24 and SEC99AA-24C? There is no technical difference; the SEC99AA-24 and SEC99AA-24C are identical parts with the same specifications and fittings. Are the Schrader depressors removable? These units feature integral depressors designed for standard pressure port engagement; refer to the specific configuration if a non-depressor end is required for the control side.
