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, CP4626, CP5623, and CP6093 series master cylinders. Not for AP CP7854/CP7855 or CP6465 rear-pivoting 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.
