Idex® Super Flangeless™ Fitting Assemblies, 1/4-28 and 5/16-24 Flat Bottom

Flat-bottom fitting assemblies withstand high pressures
  • Eliminates tubing twist that can loosen connections
  • Resistant to loosening through vibration
Super Flangeless™ fitting assemblies are an excellent choice for tubing assemblies and will stay tight even through vibration. One-piece PEEK fittings are reusable that require no swaging. Two-piece fittings come with ferrules 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.
