The 1/4-28 Pre-Torque Flangeless Fitting is a durable and super-handy connector for microfluidic systems. It is available in four sizes for tubing with 1/16" (1.6 mm), 2.0 mm, 2.5 mm, and 1/8" (3.2 mm) rigid tubing OD and is sold in a convenient 10-pack.
General
This Pre-Torque Flangeless Fitting is a high-performance solution designed to create a secure, high-pressure seal with rigid tubing. Its unique pre-torqued design ensures a perfect, leak-tight seal every time by preventing the common problems of over- and under-tightening. While the fitting body is manufactured from PEEK (Polyetheretherketone), the internal ferrule is made of ETFE (Ethylene tetrafluoroethylene). This combination of materials leverages the robust mechanical strength of PEEK with the excellent chemical resistance and low friction of ETFE, making it a top choice for demanding lab scenarios and machine assembly.
Features
- Pre-Torque Design: A defining feature of this fitting is its unique pre-torquing mechanism. It is designed to prevent both under- and over-tightening, therefore avoiding leakage. The nut will click or stop turning once the optimal seal is achieved, guaranteeing a leak-tight connection without the risk of crushing the tubing or damaging the receiving port.
- PEEK & ETFE Construction: The PEEK nut provides exceptional mechanical strength and pressure tolerance, while the ETFE ferrule offers a high degree of chemical inertness to a vast range of aggressive solvents, acids, and bases. This ensures the connector will not degrade over time and will not leach contaminants into your samples.
