Welcome to CYLEX’s premier solution for high-purity fluid handling systems. Our PFA Bead-Lock Compact Tee Fitting is meticulously crafted to meet the rigorous standards of industries where contamination and failure are not an option. This fitting delivers unmatched performance, ease of installation, and space efficiency.
Key Features & Benefits:
● Superior Material: Manufactured from high-purity, virgin PFA. Offers excellent chemical resistance to virtually all aggressive media and operates across a wide temperature range (-190°C to 260°C / -310°F to 500°F).
● Secure Bead-Lock Connection: The patented mechanism (compatible with major brands) firmly grips the bead on your PFA tubing, providing a strong, leak-free, and vibration-resistant seal that won’t fail under pressure.
● Space-Saving Compact Design: Its low-profile geometry allows for installation in incredibly tight spaces, simplifying complex manifold designs and freeing up valuable real estate in your equipment.
● Quick-Connect Functionality: Dramatically reduces installation and maintenance time. No special tools required for connection—just push until it clicks. A special disassembly tool allows for easy removal and reconfiguration.
● For High-Purity Applications: The inert, non-stick surface of PFA minimizes particle shedding and prevents fluid adhesion, ensuring the integrity of your ultra-pure water, chemicals, and process fluids.
Technical Specifications:
