Perhaps the most significant advantage of slotted hex head washers is their ease of installation
Some disadvantages of NBR are poor ozone, sunlight and weather resistance as well as limited high temperature and flame resistance. For higher temperature resistance, a much better material to use is Silicone.
- Oil seals, also known as shaft seals or grease seals, are essential components used to prevent lubricants from escaping and contaminants from entering a machine. They are commonly found in vehicles, industrial equipment, and household appliances. Without oil seals, machinery would quickly wear out and break down due to insufficient lubrication and contamination.
Both sealing types are popularly used in different mechanical engineering applications. How are they different? The article explains the fundamental working mechanism of both categories of seals.
If it was stuck to the cover, smear gasket sealant along the cover flange and upper gasket and leave it to dry for a few minutes.
- Oil seals are a critical component in the operation of machinery, providing a vital barrier between the internal lubricated parts and the external environment. These seals prevent the leakage of oil, which is essential for the proper functioning of the machine's components. They also prevent contaminants from entering the system, maintaining the quality of the oil and ensuring its longevity.

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


Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.
Oil Seals, also known as fluid seals, grease seals, dirt seals, shaft seals, or lip seals, help to seal the gap between static and moving components in machinery and equipment. Oil Seals used in rotating applications are known as rotary seals.
Silicone Oil Seals - Designed to absorb lubricants in order to lessen wear and friction, silicone rotary shafts also offer high thermal resistance and a large temperature range. But, they do not handle abrasions well or interact with oxidized oils.

we offer oil seals made from the highest quality materials to ensure durable, reliable seals for a variety of applications. Our state-of-the-art machining services allow us to deliver custom seals to meet customer requirements for quantity, size, style, profile, and materials.

What should you take into account when selecting an oil seal? Different types of oil seals and various types of materials are available, each designed for specific uses. It is also important to select the right size of oil seal for the best results. For this reason, selecting the right oil seal requires adequate understanding of the application in which it will be used.
