Additional Info:
The 58819‑01‑1 Two‑Piece PEEK Tubing Connector Nut is a low-pressure flangeless fitting designed for connecting 1/8 inch OD polymeric tubing in HPLC systems and other fluid handling applications. Featuring a two-piece construction, this fitting provides improved grip, alignment, and repeatability during installation.
This design includes a large head for better handling and a short overall length, making it especially useful in tight instrument spaces where clearance is limited. The finger-tight configuration enables quick, tool-free connections while maintaining reliable sealing performance when used with compatible ferrules.
Manufactured from natural (unpigmented) PEEK, this fitting offers enhanced chemical resistance, mechanical strength, and low extractables, making it suitable for sensitive analytical applications.
