What are Rubber Oil Seals?

Rubber oil seals, also known as oil seals, are popularly used components in various industrial applications especially to prevent the leakage of fluids, such as oils or lubricants, from machinery or equipment. Made to fit tightly around rotating or moving shafts, these industrial oil seals, efficaciously create a barrier between the inner workings of the machine and the external environment.


As they are made from synthetic rubber materials, such as nitrile rubber, these seals offer excellent sealing properties, along with resistance to oil and other fluids. The rubber material is molded into a ring shape, often with a metal casing or reinforcement to provide structural support and ensure durability.

Steps to Install Rubber Oil Seals Properly

Following the steps below leads to a proper installation of industrial rubber seals when used in your applications.

1. Prepare the Surface: Take out the oil seals from their packaging only just before installation. Before installing the rubber oil seal, make sure the surface where it will be installed is clean and free of any debris or contaminants. Wipe the surface with a clean cloth or use a solvent if necessary to remove any grease or oil.
2. Inspect the Rubber Oil Seal: Before blindly installing the seal, have a thorough check and inspect the rubber oil seal for any damage or defects. Ensure to use a seal of the correct size and type for your application.
3. Apply lubrication: Apply a thin layer of lubricant to the industrial oil seal. This will help the seal slide into place smoothly and prevent any damage during installation.
4. Position the seal: Now carefully position the rubber oil seal on the designated area. Ensure that the seal is aligned correctly and evenly with the surface. Avoid stretching or distorting the seal during this step.
5. Use a seal installation tool: To securely install the seal, it is advisable to use a seal installation tool. This tool is specifically designed to prevent any damage to the seal and ensure a proper fit. If you need advice on the right tool, get in touch with the oil seal manufacturer.
6. Apply consistent pressure: When installing the seal, ensure to apply consistent and even pressure around its circumference. You can gradually push the seal into its housing with a gentle, tapping motion. Applying excessive force can deform or damage the seal.
7. Check the seal: Once done with the installation, double-check that it is seated correctly and evenly. Ensure that the seal is flush with the surface and there are no gaps or misalignments.
8. Test for leaks: Testing the rubber oil seal for leaks is the last and crucial step. Apply appropriate fluid or pressure to the sealed area and carefully observe for any signs of leakage. You may make necessary adjustments or repairs to ensure proper sealing.

If you are still confused and have more doubts about rubber seals and their installation, get in touch with trusted oil seal manufacturers such as SSP Seals. With their expertise and experience, they can provide you with comprehensive information and guidance to ensure the successful use and installation of these seals.

In this article, we’ll demystify these essential components, focusing on their types and materials, and discussing how to select the right one for your precision engineering machinery.

Oil Seal Types 

When it comes to types of rotary shaft oil seals, there's a variety from which to choose, with the Trusted Containment (TC) seal being one of the most common.

Often referred to as the R23, TC oil seals feature a distinctive double-lip design that is equipped with a self-tightening spring. This innovative design ensures effective containment and sealing of lubricants, making them a preferred choice in various applications. The double-lip of TC seals offers enhanced sealing capabilities, especially in environments in which preventing contamination is critical.

Oil Seal Sizes 

Oil seals are sized based on three critical dimensions:

• Inside Diameter (ID)
• Outside Diameter (OD)
• Width (W)

Typically, standard sizes are marked directly on the seal which simplifies the process of identifying and ordering the correct seal for your specific application. However, if you are unsure which size seal you require, it’s advisable to seek professional advice from the experts at BTL UK.

Materials 

Oil seals are manufactured from a variety of materials, each of which is suited to specific operational needs, so it is important to select the most appropriate one for your application. NBR/Nitrile and FKM/Viton are popular due to their compatibility with a variety of operating conditions.

• NBR/Nitrile: Known for its excellent heat resistance and durability, NBR/Nitrile is a versatile material suitable for a range of applications.
• FKM/Viton: As well as excelling in high-temperature environments, FKM/Viton is renowned for its strong resistance to chemicals and heat.
