MH: O.D. wall is a rubber material

MH(S)H: O.D. wall is metal with a reinforced inner metal case- The double lip configuration is no mere coincidence; it serves a dual purpose that enhances its effectiveness. The primary lip faces outward, bravely confronting the harsh external environment to prevent dirt, water, and other contaminants from infiltrating the system. Meanwhile, the secondary lip guards against the escape of lubricating oil, ensuring that the machine's moving parts are adequately nourished. This harmonious partnership between the two lips ensures not only the longevity of the seal but also the efficiency and reliability of the equipment it protects.
- In addition to its durability and compatibility, the RC7YC spark plug also offers excellent performance. With a strong and consistent spark, this spark plug ensures smooth and efficient combustion, leading to improved throttle response and overall engine power. This can result in better fuel efficiency, increased horsepower, and a smoother running engine.

- The rear valve cover gasket, an often-overlooked component in an engine's intricate machinery, plays a pivotal role in ensuring optimal performance and longevity. This small but crucial element seals the connection between the engine block and the valve cover, safeguarding essential lubricants and preventing oil leaks.
Cassette seals are designed to maximise grease or oil retention and protection against liquid or solid contaminants. These seals are provided with their own bushings in which dirt is kept out and oil/grease kept in by a multi-lip seal.
- Moreover, die-cut silicone gaskets are known for their excellent electrical insulation properties. They protect electrical connections from environmental factors, ensuring safe and efficient operation in electronic devices and equipment. This feature, coupled with their resistance to ozone and UV radiation, makes them a popular choice for outdoor applications.
Heat resistance

318 valve cover gasket. The old gasket must be carefully removed, and the surface of the valve cover and cylinder head cleaned before installing the new gasket. It is important to torque the bolts to the specified requirements to ensure a proper seal and prevent any leaks.

Silicone oil seals, which are also called VMQ, have strong resistance to temperature, which ranges from -140 degrees Fahrenheit to 392 degrees Fahrenheit. They are also resistant to ozone, light, and harsh weather conditions. Silicone is frequently used in hydraulics and pneumatics, as well as in the food and medical industries. Due to the material’s transparency and flexibility, it’s commonly chosen for the manufacturing of o-rings, molded parts, and flat seals, as well as electrical insulators.
What Are Oil Seals?

Finding oil spots under a parked vehicle can be both worrying and stressful for any vehicle owner. If the seal’s leak is small, oil may start to accumulate on the underside of the engine. But as the leak gets bigger, the oil leak will become visible in the front side of the engine.
