EasyLok™ fittings are composed of a knurled stainless steel nut and a double ended PEEK™ ferrule

• Double ended ferrule seals at two points
• Knurled to make finger tightening easy

These fittings are compatible with any standard female HPLC fitting including Swagelok®, Parker™, Waters®, Valco®, and Whatman®.

The PEEK™ ferrule slides over any 1/16" OD tubing to its required position, while the nut is finger tightened. Unlike stainless steel, the PEEK ferrule will not crush the tubing and can be easily readjusted for quick column changes. The unique double ended ferrule design seals at two points to prevent leaks. The fittings are compatible with any standard female HPLC fitting, including Swagelok®, Parker™, Waters®, Valco® and Whatman®. EasyLOK fittings are recommended for use with SGE GLT™ columns.
