Johnson Controls SEC99AB-24 Armored Capillary

The Johnson Controls SEC99AB-24 is a professional-grade UltraCap Armored Capillary engineered for high-reliability pressure connections in commercial refrigeration and HVAC systems. Designed to interface seamlessly with PENN pressure-actuated controls, this 24-inch assembly features an internal copper capillary with a 0.06" ID, protected by a rugged brass armor sleeve. This construction is specifically built to mitigate pressure pulsation and provide superior abrasion resistance against the constant vibration inherent in compressor housings and rack systems. This model, which is technically identical to the SEC99AB-24C, simplifies field installation with its versatile configuration: one straight female flare fitting and one 90-degree elbow, both equipped with 1/4" SAE connectors and Schrader valve depressors. The armored capillary tubing ensures zero refrigerant effusion, maintaining system integrity across a wide temperature range of -50?F to 350?F. Rated for a maximum working pressure of 600 psi and a burst pressure of 3,000 psig, the SEC99AB-24 is a durable alternative to standard copper pigtails, compatible with all common non-corrosive refrigerants.

• Vibration Protection: The brass armor sleeve shields the copper core from mechanical wear and fatigue caused by high-frequency system harmonics.
• Pulsation Dampening: The 0.06" small-orifice design effectively smooths out pressure spikes to protect sensitive control bellows.
• Leak Prevention: Solid copper internal tubing eliminates the porosity issues often found in synthetic hoses, ensuring no refrigerant loss.
• Installation Flexibility: The combination of a straight and 90-degree fitting allows for clean routing in tight mechanical compartments.

Common Questions & Technical Insights Is the SEC99AB-24 compatible with R-410A and R-290? Yes, the UltraCap series is compatible with all common non-corrosive refrigerants; however, always verify that your system operating pressures do not exceed the 600 psi working pressure limit, especially in high-side R-410A applications. What is the benefit of the integrated Schrader depressors? The built-in depressors allow for direct connection to service ports without the need for additional adapters, ensuring the internal valve is actuated immediately upon tightening for accurate pressure sensing. Can I use this as a permanent replacement for a standard copper pigtail? Absolutely. Many technicians prefer the armored capillary assembly because it is less prone to work-hardening and kinking during maintenance compared to traditional 1/4" copper lines.
