- Gaskets are essential components in various industries, providing sealing solutions for pipes, tanks, and other equipment. Molded gaskets, also known as compression gaskets, are one of the most popular types due to their versatility, durability, and cost-effectiveness. In this article, we will provide a comprehensive guide to molded gaskets, including their types, materials, manufacturing processes, applications, and maintenance.
- The versatility of silicone oil seals is another compelling factor
There are a wide range of oil seals to select from for any number of uses, so this guide will break down the most common seals to help you choose the right one for whatever piece of machinery you are working on.
Sealing lip
Our rubber seals are used in the following industries:
If the gap is larger than 0.002 in. (0.05 mm) at any point, have the head or block checked and machined flat by a specialist.
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.
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.
Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fitting
In this article, we’ve discussed everything you need to know about oil seals, which are sometimes called radial shaft seals. Also, we’ve discussed the various types, their installation, and how to choose the right one for your application. With all these, you will be able to make an informed decision about the best oil seal for your needs.
First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
