SEC99AB-18C Johnson Controls ARMORED CAPILLARY

Overview

The Johnson Controls SEC99AB-18C is a high-reliability UltraCap armored capillary assembly designed for pressure connections in refrigeration and air conditioning applications. It connects seamlessly to standard 1/4 inch SAE male flare connectors, such as those found on PENN pressure-actuated controls. The rugged brass armor sleeve protects the internal copper capillary tube from physical damage, vibration, and abrasion in demanding commercial HVAC/R environments, while the small-orifice design minimizes pressure pulsations to extend service life and maintain measurement accuracy.

Features

• Armored brass sleeve design provides superior protection against mechanical damage and vibration-induced abrasion.
• Internal copper capillary tube guarantees zero refrigerant effusion to the environment.
• Small-orifice capillary minimizes pressure pulsations from compressor operations.
• Versatile configuration features one straight fitting and one 90-degree elbow fitting.
• Equipped with breakaway Schrader valve depressors on both ends to facilitate straightforward installation and positive valve actuation.
