PEEK HPLC Fittings

Peek (polyetheretherketone) fingertight fittings are convenient, inert, and biocompatible. Use these fittings with 1/16 in. O.D. PEEK, stainless steel, titanium, Tefzel, or PTFE tubing. PEEK fittings are compatible with all HPLC solvents (avoid concentrated sulfuric and nitric acids), and can be used at temperatures to 150° C. Unlike stainless steel ferrules, PEEK ferrules do not permanently lock into place on the tubing. This allows you to interchange fittings with tubing and columns, from manufacturer to manufacturer (e.g. from Agilent to Waters), and still form a zero dead volume, leak-free connection. All fittings in this section can be used with internal fittings provided by most major suppliers.
