Most people know that billet aluminum is a lot tougher than plastic and that toughness means fewer problems over the long haul. So, replace your fragile plastic factory air bleeder screw with the longer lasting billet aluminum PPE Air Bleeder Screw. Damage and distortion that comes naturally with a plastic unit from routine servicing will no longer be a problem because PPEs Air Bleeder Screw features a Nitrile O-ring and billet aluminum construction.
_ Machined air channel on threads to bleed air (Beware of imitation bleeder screws without air channel)
_ Bio diesel compatible Nitrile O-ring
Available for 2001-2016 Duramax diesel engines
Bleeder screw works perfectly with Water Level Sensor Wrench.
