Wear and oil loss remains two of the most frequent signs of engine seal failure and, if not paid attention to, it can give rise to a breakdown in the vehicle’s system. Regular maintenance and routine oil changes minimize the issues associated with oil seals and potential oil loss.
Proper installation of the 25x47x7 oil seal is essential to ensure its effectiveness. It is important to carefully clean and prepare the surfaces where the seal will be placed, as any dirt or debris can compromise the seal's ability to function properly. Additionally, the seal should be installed with the correct orientation and pressure to create a tight and secure seal.




Industrial oil seals are critical components used in a wide range of industrial machinery and equipment to prevent the leakage of lubricants and the ingress of contaminants. These seals play a vital role in maintaining the efficiency and longevity of industrial machinery by ensuring the proper containment of lubricants and protecting internal components from wear and damage. Industrial oil seals are utilized in various applications, including pumps, compressors, hydraulic systems, and manufacturing equipment.
As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.
The first material that we are going to look at is Nitrile Buna- N 70 or NBR for short.
