No, Partisil™ HPLC columns are a complete column and no extra end fitting kit is required.
This column has the standard compression end fittings, WCS.
It is the Partisphere™ which is a cartridge type HPLC column and needs an end fitting kit.
It has a unique void sealing hardware named WVS. All WVS cartridge columns are shipped without end fittings and an require end fitting kit. The idea of a cartridge system is to have one or two sets of end fittings that are removable and can be used interchangeably on the cartridges as you install them on the instrument.
