These Lockheed kits include both the primary and secondary annular* seals. These kits fit the old Lockheed "tin can" style masters as well as newer AP Racing CP2623, CP4400, CP4623, CP5623, and CP6093 series master cylinders.

Lockheed used the shape of the nose on the front of the master cylinder to identify bore sizes on the old "tin can" style master cylinders.
