Automotive applications also rely on square rubber gaskets for a wide range of sealing requirements. From sealing doors and windows to engine components and exhaust systems, these gaskets play a crucial role in maintaining the safety and performance of vehicles.
China is a significant hub for the wholesale and manufacturing of spark plugs, catering to both domestic and international markets. The country's robust manufacturing infrastructure and expertise in automotive components have positioned it as a leading producer and supplier of spark plugs. Chinese spark plug manufacturers offer a wide range of products, including standard, performance, and specialty spark plugs, catering to diverse customer needs and vehicle applications.
ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.
Nitrile Butadiene Rubber (NBR, nitrile)

Wear and oil loss remains two of the most frequent signs of engine seal failure and, if not paid attention to, it can give rise to a breakdown in the vehicle’s system. Regular maintenance and routine oil changes minimize the issues associated with oil seals and potential oil loss.
After the oil seal is positioned in the groove, apply even pressure to the oil seal using a seal driver or a similar tool. This will help to seat the oil seal firmly in the groove and prevent it from moving during use. Make sure to apply the pressure evenly and gently, as applying too much force can damage the oil seal or cause it to deform.
