Standard PEEK internal unions enable easy connection of transfer/solvent lines. Completely inert and biocompatible, they are usable with most common organic and inorganic HPLC solvents without risking corrosion, metal contamination, or protein degradation that might occur with stainless steel.
Small diameter bores ensure low dead volume connections. These unions have the standardized Valco fitting details with a smooth transition of the taper into the threaded part. Connections to these PEEK unions can be made with any 10-32 fitting that uses polymeric ferrules.
PEEK unions are available in body-only versions as well as complete with VICI-Jour PEEK one-piece fingertight fittings ready to connect to any 1/16" OD tubing.
