Federal Mogul FP590GB312B Intake Manifold Gasket for Mack E6 E7 E-Tech ASET Engines

The Federal Mogul FP590GB312B is a heavy-duty intake manifold gasket engineered for select Mack diesel engines, including the E6, E7, E-Tech, and ASET series. This gasket seals the critical interface between the intake manifold and the cylinder head, preventing vacuum leaks and maintaining optimal airflow to the combustion chambers.

Constructed with a stamped steel core bonded with rubber along the gasket's edges, this design delivers dimensional stability while providing localized conformity around coolant and oil passages. The steel carrier resists blow-out under pressure, while the rubber edging accommodates minor surface imperfections and joint movement to reduce the risk of fluid leakage.

Key Features:

• Direct-fit replacement for Mack E6 (2VH–4VH), E7, E-Tech, and ASET series diesel engines
• Steel-bonded rubber construction for strength and reliable sealing
• Resists thermal cycling, vibration, and pressure fluctuations common in heavy-duty diesel applications
• Two (2) gaskets required per complete engine installation
• Meets or exceeds OEM sealing specifications

OEM Cross-Reference Numbers: 590GB312B, 590GB312, 590GB312A, 590GB355, 25099902, 4103-5200540584, 4103-5010284154, 4103-5000840882

Replacing a worn or damaged intake manifold gasket is essential to restoring proper compression, preventing coolant contamination, and maintaining long-term reliability in Mack diesel powertrains. This gasket is also a core component of several complete engine gasket kits for these engine families.
