Why are 3D drawings the same of your quarter turns for the sealed and non sealed fasteners?

The 3D drawings of our quarter turn turnlocks we provide are a simplified design.

they do not contain all the interial components.

for the HGR : high duty grommet retained series, there exist two versions: standard is non-sealed.

the 3D drawing of the sealed version of the quarter turn looks the same.

reason: there is a shorter spring with the Gasket Versions to allow the additional O-Ring.
If both parts are simplified or totally removed the remaining part looks the same as the non-gasket version
