Color-Coded Nuts for Flangeless 1/4-28 Connections

color-coded flangeless nut
  • Polyacetal - economical alternative to PEEK
  • Compatible with all 1/4-28 flat-bottom ports
  • For 1/16" or 1/8" OD tubing
  • True fingertight - no tools required

Polyacetal flangeless nuts in combination with the inverted ferrule do not require a flanging tool. A hand-tightening procedure makes leak-free seals.

With this fitting system, the inert ETFE ferrule is the only part besides the tubing which comes into contact with the fluid stream - the nut is never in contact. Six colors are available.
