• Stem Seal Pliers: Extends around the valve stem into restricted areas to clamp the seal securely for clean removal or installation — without damaging springs or seals.
• Safe, Pressurized Design: The valve is held closed by pressurized air, preventing it from dropping into the combustion chamber during service.
