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.

Sonnax 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
