Technical Notes

The HX83 turbocharger gasket is a C-shaped metallic seal designed for specific housing interfaces on Cummins QSK50 engines. The visible profile includes a circular hole on one lobe and a semi-circular notch on the other, which helps align the seal with the turbocharger flange during installation.
