OE end plugs are designed to prevent critical pressure loss by capping the bore, while also functioning as a spring or valve stop. Repetitive spring motion, valve impact and fluid pressure variations cause wear between the end plug and bore mating surface, allowing vital pressure to escape the circuit. O-ringed end plug kit 35740-45K services three individual bores in ZF8HP50, ZF8HP75 and Chrysler 850RE valve bodies which use internal end plugs to isolate valves from solenoids. These double O-ringed internal end plugs replace damaged OE plugs and restore pressure containment to the bores. Also included are single O-ringed end plugs that service the two 13mm bores in these valve bodies. * Prevents loss of critical pressure* Services all 5 bores where end plug sealing is critical for proper function* Drop-in Zip Valve parts install quickly and easily [Learn More About Zip Valve Drop-In Repairs]/zip_valve
