When you are installing or replacing a Johnson Controls SEC99AB-36 UltraCap Armored Capillary, you need a component that withstands the constant mechanical stress of commercial refrigeration environments. This 36-inch HVAC pressure control hose is engineered with a small-orifice 0.06" internal diameter to effectively dampen refrigerant pressure pulsation, protecting your sensitive PENN pressure-actuated controls from erratic readings and premature wear. The brass armor sleeve is a specific design choice for technicians dealing with high-vibration equipment, as it provides a rugged barrier against abrasion and structural fatigue. Featuring a 1/4" SAE female flare connection with an integrated Schrader valve depressor at both the straight and 90-degree ends, this capillary ensures a secure, leak-free interface without refrigerant effusion. Compatible with all non-corrosive refrigerants, it supports a maximum working pressure of 600 PSIG and a burst rating of 3,000 PSIG, making it a reliable standard for commercial HVAC applications and industrial cooling systems. Key Benefits for the Technician: Vibration Resistance: The brass armor prevents mechanical rubbing and fatigue-related leaks in high-vibration compressor housings. Pulsation Dampening: The 0.06" precision capillary orifice stabilizes needle movement and control response in pressure-sensitive switches. Ease of Routing: The combination of a straight fitting and a 90-degree elbow allows for tight-clearance installations in packed mechanical rooms. Universal Compatibility: Designed specifically for use with the PENN line of pressure controls and standard 1/4" male flare fittings. Extreme Temperature Range: Rated for operation from -50?F to 350?F, ensuring performance in both low-temp refrigeration and high-ambient conditions. Common Questions: Does this capillary require additional gaskets or seals? No. The 1/4" SAE female flare fittings use a forged brass nut and copper stem to create a metal-to-metal seal against standard male flare connectors. A torque of 8?10 lb-ft is recommended for a secure seal. Can this be used for ammonia systems? No. This unit features copper and brass construction and should only be used with non-corrosive refrigerants. Ammonia will cause rapid corrosion of the copper capillary and brass sleeve. Is the Schrader depressor removable? The SEC99AB-36 includes integral, break-away Schrader valve depressors designed to remain in place for standard pressure control interfacing.
