The pressure differential valve and switch used on several different 1967 - 1975 GM vehicles contains a pair of brass tube seats that can get damaged or deformed over time when fittings are installed and removed multiple times. Our kit includes a pair of brand new brass tube seats that will restore proper sealing surfaces. Be sure to check out our brake valve brass seat puller tool that you can use to remove your damaged seats. These seats measure 0.450" long x 0.432" wide x 0.380" wide. We also have single seats available.
These seats will also fit the GM 5460346 master cylinder used on 1967 Camaros equipped with front disk and rear drum brakes.
