Dechengwang provides a full line of seal types, including PTFE seal, which is recognized as the best seal and the future of the seal industry. Amongst all other PTFE component manufacturers, Dechengwang stands out with unique products and services, as well as outstanding manufacturing capabilities.

The piston oil seal is located between the piston and the cylinder wall. Its main function is to seal the combustion chamber and prevent oil from leaking into the combustion area. This is essential for maintaining proper lubrication of the piston and preventing damage due to overheating and friction.

Regular inspection and maintenance of spark plug wires and spark plugs are essential to identify signs of wear, damage, or deterioration. Proper replacement of worn or fouled spark plug wires and spark plugs is crucial for maintaining the efficiency and reliability of the ignition system. Adhering to recommended service intervals and using high-quality replacement components are essential for optimizing the performance and longevity of the vehicle's ignition system.

The car engine head gasket is a vital component that ensures the proper sealing of the combustion chamber, allowing for efficient fuel combustion and the containment of high-pressure gases. This gasket is subjected to extreme temperatures and pressures, making it essential to select high-quality, durable materials that can withstand these conditions. The car engine head gasket is crucial for maintaining the integrity and performance of the engine, contributing to the overall reliability and longevity of the vehicle.

When selecting rubber valve cover gaskets, it is important to prioritize quality, durability, and compatibility with the specific vehicle model. High-quality gaskets should be designed to withstand the heat and pressure within the engine, providing a reliable and long-lasting seal. Choosing reputable suppliers and manufacturers known for producing high-quality rubber valve cover gaskets is crucial to ensure the reliability and longevity of these critical components.

Modern engine oils, such as the current SG classification for gasoline engines, contain a large fraction of additives, many of which are detrimental to fluoroelastomers. The primary functions of oil-additive packages are to protect metal parts, avoid deposits in the engine, minimize oil degradation, and adjust fluid viscosity. Little attention has been paid to avoiding damage to rubber seals. Instead, elastomer producers have been expected to provide new, higher-performing products at no increased cost to auto manufacturers. Among the additives with moieties that may attack fluoroelastomers at high temperature are detergents (phenolates), dispersants (succinimides, alkylphenol amines), and antioxidants (amines, sulfides, hindered phenols).⁴ Many of these components are multifunctional, containing phenol or amine groups that can dehydrofluorinate and crosslink VDF-containing fluoroelastomers, leading to loss of elongation and eventual embrittlement. However, the rate and extent of reactions with seals are affected by many factors, including whether air is present in the system. When oil is exposed to air at high temperature, additives may undergo considerable changes. For example, a significant fraction of amines may be oxidized to amides, which have little effect on fluoroelastomers.⁵

Also, sealant should never be used on the housing and the installation guidelines, as discussed earlier, should be followed.
