The Anti-twist Flangeless Fittings have a one-to-one nut and ferrule, which allows the tube to remain in place during the twisting of the nut. It can eliminate twisting and loosening of the fitting and keeping the tube tight even during vibration.

Anti-twist Flangeless Fittings are standard fittings with elbow threads, which can be used without tools and are economical and durable. Just put the nut and ferrule on the tube and screw them into the connection.

Anti-twist Flangeless Fittings are chemically and organically resistant and are made of PPS for the nut and ETFE for the ferrule. Anti-twist Flangeless Fittings are quick and easy to install. Available in five sizes of 1.6/2.0/2.5/3.0/3.2mm outside diameter tube.
