- The versatility of the 1-inch rubber gasket extends to electrical applications as well
1 inch rubber gasket. In certain types of electrical conduits and junction boxes, these gaskets are used to create a barrier against moisture and dust, protecting sensitive electrical components from environmental damage. Here, the non-conductive nature of rubber adds an extra layer of safety by preventing current leakage.
- Historically, gasket production was a labor-intensive process, relying heavily on manual labor to cut, shape, and assemble the materials. However, with the advent of industrial automation, the landscape began to change. Early automated machines introduced consistency and increased output, allowing manufacturers to keep pace with growing demands across industries.

U-shaped silicone gaskets are versatile sealing components used in various industries for their resilience, flexibility, and resistance to extreme temperatures and environmental conditions. These gaskets are commonly employed in applications where a reliable seal is required, such as in automotive, aerospace, and industrial equipment. The U-shaped design allows for easy installation and effective sealing, making them suitable for a wide range of applications.
On some engines, you need to remove one or both manifolds (See Exhaust manifold gasket replacement ) to reach the crankcase side cover.
If the seal is being fitted to original equipment you may have some influence over the shaft and housing bore finish, but if you are replacing a worn seal you still need to take into account the condition of these 2 essential parts.

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.
These oil seals are created from a low-temperature tolerant compound. Benefits include:
Oil seals come in various shapes to fit the machine or substance for sealing.
For this reason, when designing a machine, it is important to select the oil seal that is right for that machine.
Next time, we will explain the key points to consider when selecting your oil seal.
Types Of Oil Additives
Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fitting
Almost every lip seal is constructed to have a flexible inner part that creates a dynamic seal on the moving shaft, as well as a hard outer casing that statically matches the machine-end cover. The flexible part is made from different grades of rubber, while the hard part is made of light-gauge metal or strong plastic.
