Catalog Number - 45208-F-ETFE

The 45208‑F‑ETFE Single‑Cone Ferrules (10/Pack) are designed for use with flangeless tubing connector nuts to create secure, leak‑free connections in low-pressure HPLC systems and fluidic applications. These ferrules are specifically sized for 1/8 inch OD polymeric tubing and are essential components for proper sealing in flangeless systems.

Featuring a single-cone design, these ferrules swage (compress) onto the tubing at a single point, providing a strong mechanical grip that prevents tubing slippage while ensuring a reliable seal.

Manufactured from ETFE (ethylene tetrafluoroethylene), these ferrules offer excellent chemical resistance and higher mechanical strength compared to softer materials, making them ideal for applications requiring consistent sealing performance.
