Brand new vacuum check valve and rubber seal for the vacuum brake booster on a 1965 through 1969 Lincoln Continental.
These are brand new, properly manufactured and ready to install.
Installation takes under 5 minutes. Simply pop the old seal and valve out using a flat bladed screw driver. Clean the installation surface and then insert the new check valve and seal.
I will pre-dress the seal and check valve with vacuum grease for smooth install and tight vacuum connection.
The original check valves commonly break because the plastic becomes brittle.
