Material: PEEK

Features:  Integrated ferrule / Flat head fitting.

Integrated ferrule:

Simplified Installation:

One-Piece Design: An integrated ferrule eliminates the need to handle separate components, simplifying the installation process and reducing the likelihood of assembly errors.

Time Efficiency: It saves time during setup, allowing for quicker and more efficient installation compared to fittings that require a separate ferrule.

Consistent and Reliable Sealing:

Optimal Alignment: The integrated ferrule ensures precise alignment with the tubing, providing a more consistent and reliable seal.

Leak Prevention: By eliminating the potential for misalignment or improper seating of a separate ferrule, the integrated design helps prevent leaks.

Flat head fitting:

Consistent and Secure Sealing:

Uniform Pressure Distribution: The flat head helps distribute pressure evenly across the sealing surface, ensuring a consistent and secure seal that prevents leaks.

Reliable Connections: This design minimizes the risk of uneven tightening, which can lead to leaks or fitting failure.

Reduced Risk of Overtightening:

Controlled Torque: The flat head design makes it easier to control the amount of torque applied, reducing the risk of overtightening, which can damage the fitting or the tubing.

Protection of Components: By preventing overtightening, the flat head design helps protect the integrity of both the fitting and the connected components.

Manufactured in PEEK:

Chemical Compatibility: PEEK is highly resistant to a wide range of chemicals, including organic solvents and acids commonly used in HPLC applications. This ensures compatibility with various solvents without degradation or leaching.

Inertness: PEEK is inert and non-reactive, minimizing the risk of introducing contaminants or altering sample integrity during chromatographic analysis. This property is crucial for maintaining the purity and reliability of analytical results.

Temperature Stability: PEEK fittings can withstand high temperatures typically encountered in HPLC systems, ensuring stability and reliability under varying operational conditions. This thermal stability prevents deformation or failure due to heat exposure.

Mechanical Strength: PEEK exhibits excellent mechanical properties, including high tensile strength and stiffness. This strength allows PEEK fittings to withstand the pressures and stresses associated with HPLC systems, ensuring long-term durability and reliability.

Dimensional Stability: PEEK maintains its dimensional stability even under fluctuating temperature and pressure conditions. This property ensures consistent performance and a secure fit over time, reducing the risk of leaks or fitting failures.

Lightweight: Despite its strength and durability, PEEK is lightweight compared to metals such as stainless steel, which can simplify handling and installation while reducing overall system weight.

Biocompatibility: PEEK is biocompatible and widely used in medical and pharmaceutical applications. In HPLC systems, this property ensures that PEEK fittings do not interact with biological samples or pharmaceutical compounds, maintaining sample purity and safety.
