The Johnson Controls SEC99AA-60 is a high-performance UltraCap Armored Capillary assembly designed for critical pressure control applications in commercial HVACR systems. Built with a 60-inch armored length, this component features a 0.06-inch internal diameter capillary that ensures precise dampening of pressure pulsations. Both ends are configured with 1/4" SAE female flare fittings in a straight orientation, each including a built-in Schrader valve depressor for direct connection to access ports without the need for additional adapters. This model is technically identical to the SEC99AA-60C, providing a robust solution for connecting pressure transducers, low-pressure cutouts, or high-limit controls to the main refrigeration circuit. The armored stainless steel braiding provides essential mechanical protection against vibration-induced fatigue and abrasion, which is common in compressor compartments. For contractors performing HVAC pressure control installation, the SEC99AA-60 offers a reliable, leak-resistant connection that handles high-pressure refrigerants while maintaining system integrity under heavy cycles. Key Benefits Enhanced Vibration Resistance: The armored capillary tube construction prevents work-hardening and fatigue failure caused by high-frequency compressor vibration. Universal Compatibility: Equipped with standard 1/4 inch SAE female flare fittings and depressors to fit most standard refrigeration service ports. Precision Pressure Dampening: The 0.06" I.D. minimizes gauge flutter and protects sensitive control instruments from hydraulic shock. Extended Reach: The 60-inch length provides ample slack for routing around hot discharge lines and internal components in large rooftop units or rack systems. Field Interchangeability: Direct replacement for the Johnson Controls SEC99AA-60C, ensuring seamless refrigeration parts replacement. Common Questions Is the SEC99AA-60 compatible with all common refrigerants? Yes, the materials and construction are compatible with standard HFC, HCFC, and CFC refrigerants, including R-410A and R-134a, making it a versatile HVAC capillary tube fitting. Do I need to install a separate Schrader depressor? No, this assembly comes with straight capillary tube with depressor tips on both ends for immediate engagement with access valves. How does the SEC99AA-60 compare to standard copper capillary lines? The armored coating provides superior protection against kinking and rupture compared to bare copper, specifically in high-vibration environment where HVACR technical specifications demand high durability.
