Our PEEK finger tight fittings are available in six colours, for easy identification of tubing lines. They are rated to 350bar (5000psi) and can be used in virtually any type of 10-32 thread HPLC fitting detail on the market. PVDF fittings are chemically inert, and suitable for medium pressure applications. They will not constrict soft polymeric tubing as PEEK finger tightfittings sometimes do.
