- Automotive Industry Tek screws are also utilized in automotive assembly, where strength and reliability are paramount.
NBR, also known as nitrile rubber or nitrile, is the most popular material for an oil seal because of its good resistance to many oils and greases, such as mineral grease and hydraulic oil. Depending on their composition, synthetic oils and greases, such as those based on glycol, can damage NBR rubber materials. Depending on the amount of glycol, a PTFE lip seal may be the best choice. NBR is also unable to cope with contact with acids and solvents. The rubber is suitable for oil and grease at temperatures from -35 °C to 100 °C.
- One of the key benefits of the GY6 spark plug is its ability to deliver a strong and consistent spark, even under high engine speeds and load conditions. This ensures reliable ignition of the air-fuel mixture, leading to smooth and efficient engine operation. A properly functioning spark plug also helps improve fuel efficiency and reduce harmful emissions, making it an important part of any vehicle's engine system.

The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
Prepare the shaft and prevent damage
When the oil seal material and the chemical are not compatible, there will be a chemical attack, which increases at high temperatures. The only way to remedy this is to select the right material for your application. If you’ll be dealing with harsh chemicals, choose oil seals that are made with reliable materials for their compatibility.
