SEC99AB-48C Johnson Controls ARMORED CAPILLARY

Overview

The Johnson Controls SEC99AB-48C is a 48-inch UltraCap armored capillary designed for use as a reliable pressure connection in commercial refrigeration and air conditioning applications. It connects directly to standard refrigeration and HVAC service ports, serving as a pressure transmission line for controls. The small-orifice capillary acts to minimize pressure pulsations, while the copper capillary inside the sheathing guarantees that no refrigerant effuses into the environment.

Features

• Armored brass sleeve protects the internal capillary line from kinking, vibration-induced abrasion, and mechanical stress.
• Small-orifice interior design helps mitigate and dampen pressure pulsations within the line.
• Features a high-quality copper interior tube that prevents refrigerant effusion.
• Includes a breakaway integral Schrader valve depressor in both ends for secure and immediate valve engagement.
• Configured with one straight fitting and one 90-degree elbow fitting to facilitate flexible system routing.

Applications

The SEC99AB-48C is widely utilized in commercial HVAC/R control systems to establish a secure pressure connection between the main refrigerant lines and pressure-actuated control mechanisms, such as the Johnson Controls/PENN lines of controls. It is particularly suited for installations subject to high vibration or demanding physical environments, such as commercial supermarket refrigeration, cleanrooms, and large-scale industrial air conditioning systems where secure capillary protection and line flexibility are required.
