Over time, the seal lip(s) will wear a shallow groove into the shafting due to the pressure the seal imposes upon it. Visible scoring on the shaft indicates a genuine possibility that the seal will not perform as well as intended. The potential for lubricants leaking out and particulates working their way through the seal drastically increases when placed over a worn location.

Conventional spark plugs have been the go-to choice for decades, but they come with their limitations. They can suffer from carbon buildup over time, which reduces their ability to ignite the fuel effectively. This can lead to decreased engine performance, increased fuel consumption, and even engine damage if left unchecked.

3. Combination Metal-to-Oil Seal Combination seals combine the features of both face-type and cartridge-type seals. They consist of two metal rings that are pressed together, with a sealing element sandwiched between them. The outer ring of the seal is designed to fit into a groove in the housing, while the inner ring remains in contact with the rotating shaft. Combination seals are commonly used in applications where both high pressure and temperature conditions are present.

Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.

This is one of the frequent reasons for oil seal failure, and this is majorly because of the volatility of any of the elastomer’s constituents. These causative constituents may be part of the elastomer formulation, or gases that got entrapped in the elastomer during the molding process. The deceiving fact about this failure is that sometimes the oil seal won’t show any visual sign of out-gassing, however, sometimes when the out-gassing is extreme, they shrink.

In addition to its excellent temperature resistance, it is also resistant to ozone, light, and weather conditions. Silicone can be typically found in the food and medical industry as well as in hydraulics and pneumatics. It is often the preferred material for o-rings, moulded parts and flat seals but is also commonly used for electric insulators due to the material’s translucency and flexibility.

Double Lip: Like the single lip design, this design uses a garter spring with a primary lip that seals against internal media in low-pressure applications. The secondary (or auxiliary) lip offers extra protection from dust and dirt.

Spark plugs are designed to withstand the extreme conditions within an engine, including high temperatures and intense pressure. They consist of a central electrode, surrounded by a ceramic insulator, and connected to a metal casing. When the ignition system sends a high voltage electrical current through the plug, it creates a spark that ignites the compressed air-fuel mixture in the combustion chamber. This spark is what triggers the engine's pistons to move, ultimately powering your vehicle down the road.
