This Large Replacement O-Ring for Stud Dies is used to replace a worn out gasket. This part is compatible with the HandySnap® or Pres-N-Snap® Installation Tool and the SnapRite® system. This part replaces the O-ring on the inside of the stud, the surface mount stud, the socket die (which has a base attachment for a stud) that helps to retain a stud during the installation process.

This is not a replacement part for the O-ring on the outside of the upper dies or plunger for the HandySnap® or Pres-N-Snap®.
