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 35740-30K services eight individual bores in Chrysler 845RE, ZF8HP45, ZF8HP55 and ZF8HP70 valve bodies which use internal end plugs to isolate valves from solenoids. These double O-ringed end plugs replace damaged OE plugs and restore pressure containment to the bores.

Also included are single O-ringed end plugs that service the three 13mm bores in these valve bodies.

• Prevents loss of critical pressure
• No machining or special tools required
• Services all 11 bores where end plug sealing is critical for proper function
