Johnson Controls SEC99AD-36 Armored Capillary

The Johnson Controls SEC99AD-36 Armored Capillary is a professional-grade pressure connection solution designed for high-vibration refrigeration and air conditioning systems. This UltraCap armored capillary features a 36-inch length with a 0.06-inch internal diameter (0.062" ID), specifically engineered to handle pressure pulsation that can compromise standard tubing. The SEC99AD-36 (identical to the SEC99AD-36C) utilizing a 1/4" SAE female flare fitting at both ends, with the first connection housing a straight depressor for easy access to Schrader valves, while the second remains a straight fitting without a depressor for direct control mounting. The robust brass armor sleeve protects the internal copper capillary from mechanical abrasion and fatigue, ensuring zero effusion of non-corrosive refrigerants. With a maximum working pressure of 600 psi and a broad temperature range of -50°F to 350°F, this refrigerant capillary tube is the standard for connecting pressure-actuated controls in demanding commercial environments.

Key Benefits

• Vibration Resistance: The brass armor sleeve effectively dampens mechanical vibration, preventing metal fatigue in the copper capillary tubing.
• Pulsation Dampening: The 0.06" internal diameter acts as a natural snubber, protecting sensitive pressure controls from rapid system spikes.
• Leak Prevention: High-integrity SAE female flare connections and armored construction eliminate refrigerant effusion common in lower-quality lines.
• Versatile Compatibility: Fully rated for all common non-corrosive refrigerants used in modern HVACR applications.
• Direct Fit Replacement: Serves as a 1:1 replacement for SEC99AD-36C, ensuring seamless integration with existing Johnson Controls/PENN controls.

Common Questions

Is the SEC99AD-36 compatible with R-410A systems?
Yes, as long as the system pressure does not exceed the 600 psi maximum working pressure rating, the SEC99AD-36 is compatible with R-410A and other standard non-corrosive refrigerants.

What is the difference between SEC99AD-36 and SEC99AD-36C?
Technicians should note that the SEC99AD-36 and SEC99AD-36C are functionally identical parts with the same technical specifications and 1/4" female flare fittings.

Does this armored capillary include a Schrader valve depressor?
This specific model features a straight fitting with a depressor on one end and a straight fitting without a depressor on the opposite end to suit standard control-to-port configurations.
