The success of the K-Series filter is directly attributable to the innovative quick-connect fittings that are incorporated into the design. These fittings are unique in two ways. First, they allow for the installation of the inline filter in a matter of seconds. Inlet and outlet tubes are simply snapped into place and secured using a patented collet system. Second, the fittings are molded directly into the filter body and cap as a single unit. This reduces the chance for weeping or seepage.

PurePro® K-Series inline filter has molded quick-connect fittings that are easy to insert and remove the tube, the photo on the above shows the quick-connect fitting and the below shows the tube and locking clip fitted.
 

Replacing the filters is one of the easiest to do. The K-Series inline filter features 1/4" quick-connect compression fittings that allow for installation and replacement in a matter of seconds without the use of tools.
