Reliable sealing solutions for heavy-duty earthmoving and industrial power units.
When it comes to engine overhauls, the integrity of your cylinder head sealing is non-negotiable. Our 7E3772 (also known as 7E-3772) engine head gasket is specifically engineered for the Caterpillar 3306 engine series. Whether you are operating a D6 crawler, a 966 wheel loader, or a stationary power generator, this gasket ensures a high-pressure seal that prevents coolant leaks and maintains optimal combustion chamber compression.
This 7E3772 replacement follows strict OEM standards, using a multi-layer steel or composite structure depending on the specific application needs, ensuring durability under extreme thermal cycles.

Signs of failure include "milky" oil (coolant contamination), white smoke from the exhaust, or external coolant weeping from the head-to-block mating surface. If your 3306 engine is overheating under load, inspect the 7E-3772 gasket immediately to avoid catastrophic cylinder head cracking.
Our 7E3772 utilizes an OEM-standard tri-metal structure. It is trusted by repair shops and equipment fleets worldwide for its ability to handle the rigors of construction and mining environments.
Always follow the Caterpillar service manual for the 3306 engine. Clean the block surface thoroughly. Improper cleaning is the number one cause of new gasket failure. Our technical team can provide the specific bolt tightening sequence upon request with your purchase.
