- 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.

Fluid Types - Various oil seals are able to withstand interactions with oils, fuels, grease, water and more. Knowing what type of fluid the rotary shaft seal will be in constant contact with will ensure the longevity of the seal and surrounding components.
How do oil seals work?

One option is to buy oil seals from specialised gasket and sealing material companies like Polymer Trade Manufacturing Ltd, which is known for its expertise in dealing with gaskets and o rings. These companies not only offer an extensive range of oil seals but also provide expert advice to help customers select the right sealing materials for their specific requirements.
Metal
Entry of dust and debris is one of the most common reasons oil seals fail. For instance, in high-pressure applications, even the smallest sediments can create a gap in the seal, causing the oil to leak and dirt to get in.

Even the slightest chip or dent can cause contaminants to infiltrate your oil seal. If there are any scratches on the shaft, a leak path may develop, allowing the lubricant to drip. To protect the shaft from damage, wrap it in a mesh rubber screen and store it vertically in its compartment. This way, it can be shielded from potential cracking.

Material Selection:
It is essential to regularly check and replace spark plugs as needed to ensure the engine runs smoothly and efficiently. Over time, spark plugs can wear out due to the intense heat and pressure inside the engine cylinders. Worn-out spark plugs can lead to misfires, poor fuel economy, and even engine damage if left unattended.
