HPLC EasyLok Fittings

Quick and Easy HPLC Connections

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

Features and benefits

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

Recommended applications

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