The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.

Runout must be kept to a minimum. Movement of the center of rotation is usually caused by bearing wobble or shaft whip. When coupled with misalignment, this problem is compounded. Contrary to popular belief and common practice, the installation of flexible couplings cannot correct or compensate for misalignment.

Wilmink Engine Parts offers a wide range of oil seals for various applications and engines. Poor-quality oil seals can cause problems. Our range offers only quality brands and our specialists will be happy to help you choose the right product for your application. Below, we highlight some of our brands with their catalogues around oil seals.

The valve cover gasket plays a critical role in maintaining the integrity of the engine by preventing oil leaks and maintaining proper lubrication. It ensures that the engine remains free from oil leaks, contributing to its overall efficiency and reliability. A high-quality valve cover gasket is essential for preserving the proper functioning of the engine and protecting it from potential damage due to oil leakage.

1. Oil seals have three basic components: sealing element, metal case, and spring.

Spark plug wires, also known as ignition wires or high-tension leads, are crucial components in the ignition system of internal combustion engines. These wires are responsible for transmitting the high-voltage electrical current from the ignition coil to the spark plugs, initiating the combustion process within the engine cylinders. High-quality spark plug wires are essential for ensuring efficient ignition, optimal engine performance, and reduced emissions, making them a critical component in the overall efficiency and environmental impact of the vehicle.

Selecting Quality Silicone and Rubber Gaskets

3.  TEMPERATURE: Similar to the pressure level, you need to know what temperature your machinery can operate at. You need to choose a seal that can withstand the heat or cold. PTFE have the widest rang of temperature, making them a safe option when you are uncertain of the range.

The garter spring is located at the end of the primary sealing lip and used to apply pressure to the sealing lip against the shaft. Common garter spring material types are:

The car head gasket, also known as the cylinder head gasket, is a critical sealing component in the engine that plays a pivotal role in maintaining the integrity of the combustion chamber. This gasket is designed to seal the cylinder head to the engine block, preventing the leakage of coolant, oil, and combustion gases. A properly functioning car head gasket is essential for ensuring optimal engine performance, preventing overheating, and maintaining the overall efficiency of the engine.
