SEC99AA-60C Johnson Controls ARMORED CAPILLARY

Overview

The Johnson Controls SEC99AA-60C UltraCap Armored Capillary is a high-performance capillary assembly designed for use as a reliable pressure connection in commercial refrigeration and air-conditioning applications. Featuring a 60-inch length, this component utilizes a small-orifice capillary to minimize pressure pulsations and a brass armor sleeve to protect against abrasion and vibration-induced fatigue. It is equipped with two straight 1/4-inch SAE female flare fittings, including a built-in Schrader valve depressor in one end for direct connection to access ports without extra adapters.

Features

• UltraCap armored design provides enhanced durability, mechanical protection, and kink resistance.
• Small-orifice capillary design effectively dampens and minimizes pressure pulsations.
• Copper capillary construction inside the sleeve ensures no effusion of refrigerant to the environment.
• Two straight fittings with 1/4-inch SAE female flare connections ensure a secure, leak-free installation.
• Integrated Schrader valve depressor allows for positive valve actuation and direct connection.
• Broad compatibility with all common non-corrosive refrigerants.
