1/4-28 Fingertight Nuts PEEK (Flangeless)

PEEK flangeless nuts in combination with our inverted ferrule do not a require 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. Ferrules are not included. Order separately.

• Compatible with all 1/4-28 flat-bottom ports
• Excellent chemical resistance
• For 1/16" or 1/8" OD tubing
• True fingertight - no tools required
