1/4" Graphite Vespel Ferrule

The 1/4" Graphite Vespel Ferrule is a high-performance sealing solution designed for gas chromatography (GC) applications. Composed of a 60% Vespel / 40% graphite composition, it delivers an optimal balance of sealing integrity, durability, and ease of installation. Designed for vacuum and high-pressure environments, this ferrule requires minimal torque, ensuring a secure, leak-free seal with reusability. With a temperature stability of up to 400°C, it performs reliably in high-temperature transfer lines and demanding GC-MS workflows.
