- Applications
- 1. Cost High temperature rubber gaskets are generally more expensive than other types of gaskets, which may limit their use in some applications.
- The versatility of rubber as a material makes square rubber gaskets highly sought after. Rubber, with its inherent elasticity, can withstand a wide range of temperatures, from freezing cold to scorching heat, without losing its shape or effectiveness. It also offers excellent resistance to chemicals, pressure, and wear, making it ideal for use in harsh environments.
-40 °C to + 90 °C
- A U-shaped silicone gasket, as the name suggests, is a ring-shaped seal with a distinctive 'U' cross-section. It's primarily composed of silicone, a material renowned for its remarkable flexibility, durability, and temperature resistance. Silicone, being a synthetic rubber, offers a wide range of benefits that make it ideal for various applications. It can withstand extreme temperatures, from sub-zero environments to scorching heat, making it suitable for both domestic and industrial use.

Oil seals are available in an immense range of sizes, for shafts from a few millimetres to several metres. Once the shaft diameter, groove diameter (housing diameter) and groove width are known, selecting an appropriate oil seal is a simple task. An oil seal or its product description is usually associated with three dimensions, for example 6x15x4. These refer to the sizes of the hardware for which the oil seal is designed. In this example, this oil seal is suitable for: 6-mm shaft diameter x 15-mm groove diameter x 4-mm minimum groove width.

Oil seal type or shape
The dimensions of the 25x47x7 oil seal refer to its inner diameter, outer diameter, and thickness, respectively. These measurements are important in ensuring a proper fit for the seal in the machine or engine it is intended for. By providing a secure seal between moving parts, the oil seal helps to maintain proper lubrication in the machine and prevent the loss of oil.
There are various sizes of industrial and ordinary oil seals, ranging from 0 to 33cm (13in). These varieties are also designed for different temperatures. As long as your seal matches the original equipment it’s intended for, you can be sure your machine will perform at its best.


By preventing lubricants from escaping, they protect key components of machinery from being damaged by leaks of various fluids. Everything from car engines to assembly machines use these oil seals to remain free from any harmful interactions that can cause serious and expensive damage to any of their critical parts.
