SEC99AA-18C Johnson Controls ARMORED CAPILLARY

Overview

The Johnson Controls SEC99AA-18C UltraCap Armored Capillary is designed for use as a reliable pressure connection in refrigeration and air conditioning applications. It features a small-orifice copper capillary that minimizes pressure pulsation, surrounded by a durable brass armor sleeve that provides excellent mechanical protection against abrasion caused by equipment vibration. The copper construction ensures there is no effusion of refrigerant into the environment, offering a secure, leak-free connection.

Features

• UltraCap armored capillary design for enhanced mechanical and abrasion protection.
• Equipped with two straight fittings at both ends.
• Includes integral Schrader valve pin depressors in both ends.
• 1/4-inch SAE female flare internal connectors for secure installation.
• Premium copper tubing paired with a protective brass outer sleeve.
• Resistant to vibration, preventing early wear and material failure.
