Cometic Nissan QR25DE 2.5L 90.0mm .040 inch MLS Head Gasket for 02-06

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example for your 2002-2006 Nissan Altima or Sentra with the QR25DE 2.5L engine. When you're rebuilding the top end or replacing a blown head gasket, you need a seal that can handle the heat and pressure of modern engines without needing extra sealants. This gasket is built for that job.

It's constructed from multiple layers of stainless steel, which gives it strength and helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C) and works well with different engine block and head materials, like aluminum heads on cast iron blocks. The center layer is also stainless steel and can be varied in thickness; this particular gasket is 0.040 inches thick with a compressed operating thickness of 0.036 inches, and it has a 90mm bore, fitting your QR25DE engine perfectly. This design means it can handle the shearing forces between different metals and provides a reliable seal right out of the box.
