Super Flangeless™ ferrules combined with nuts are an excellent choice for tubing assemblies and will stay tight even through vibration. Ferrules come with lock ring to hold the ferrule in place, preventing the nuts from sliding off in tubing assemblies. The lock ring also allows tightening without twisting the tubing.

This TinyTight Ferrule made of PEEK and stainless steel is used with a 6-40 threaded nut and tubing with a 1/16" outer diameter. It delivers a precise pressure range, and is an easy to use alternative for Lee Company 062 MINSTAC fittings systems.
