However, it’s plagued with a few drawbacks, such as poor resistance to ozone, sunlight, and weather. It also has limited resistance to high temperatures and flames.
The 40mm rubber gasket is a versatile sealing solution that is commonly used in plumbing systems, automotive engines, hydraulic systems, and other machinery where a tight seal is required. Made from high-quality rubber materials, these gaskets are designed to withstand high temperatures, pressure, and chemicals, making them suitable for a wide range of applications.
Because the inner diameter of the oil seal must be stretched during assembly, it is necessary for the shaft to possess a ramped edge. The angle at which the ramped taper should be chamfered is 30° a 50°. If a flange or keyway is present on the shaft, it is best to use a bushing. The bore should also have a chamfer of 30° over at least 1 mm on the ramped side. Be sure to round off the edges properly in the process.
Before Installation
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.
When it comes to maintaining the performance of your vehicle, one of the most important components to consider is the spark plug. The spark plug plays a crucial role in igniting the air-fuel mixture in your engine's combustion chamber, which in turn powers your vehicle. Among the various brands and types of spark plugs available in the market, Mico spark plugs are known for their quality and reliability.
Viton (FKM/FPM) Oil Seals
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.
The sealing lip is always made of a rubber or synthetic material. For oil seals with a rubber outer case (R, RST, GR, GRST), the rubber quality of the sealing lip and the outer case are the same.

In chemical plants, they resist corrosive chemicals, protecting both equipment and personnel. Always start by making sure the oil seal is facing the right direction. The oil seal must be positioned with its spring to the side of the medium to be sealed. The oil seal must then be pressed into the bore. It must fit tightly (H8 in the groove is recommended). Use appropriate tools for this, such as an impact socket set, to ensure that the force is applied evenly during pressing. The oil seal must never be hammered into the bore with brute force, but eased in.
