SEC99AD-48C Johnson Controls ARMORED CAPILLARY

Overview

The Johnson Controls SEC99AD-48C is a 48-inch UltraCap armored capillary tubing assembly designed to function as a reliable pressure connection in refrigeration and air conditioning applications. It features a small-orifice copper capillary inside a brass armor sleeve that protects against vibration-induced abrasion while effectively minimizing pressure pulsations. Equipped with a straight flare fitting on one end and a 90-degree elbow flare fitting on the other, this durable tube ensures tight, leak-proof connections without refrigerant effusion.

Features

• Vibration Resistance: Heavy-duty brass armor sleeve guards the internal copper line against mechanical wear and friction.
• Pulsation Dampening: Engineered with a small internal orifice to reduce high-pressure pulsations from the compressor.
• Leak-Proof Architecture: Continuous copper core prevents refrigerant escape, maintaining system efficiency.
• Smart Fittings: Includes one straight female flare fitting and one 90-degree elbow fitting for versatile positioning.

Specifications

• Tube Length: 48 inches (1,219 mm)
• Inner Diameter: 0.062 inches (1.5 mm)
• Outer Diameter: 0.125 inches (3.0 mm)
• Fitting Size: 1/4 inch SAE Female Flare
• Maximum Operating Pressure: 600 psig to 690 psi
• Burst Pressure: 3,000 psig
• Operating Temperature Range: -50°F to 350°F (-46°C to 177°C)
• Materials: Forged brass nut, copper stem, copper tubing, and brass sleeve

Applications

• Commercial refrigeration and HVAC systems requiring dependable pressure sensor hookups.
• Connective links for pressure-actuated controls, such as Johnson Controls or PENN line switches.
• High-vibration environments where traditional bare copper capillary tubes are prone to rubbing and failure.
• Systems utilizing any common non-corrosive refrigerants.
