  • Oil seals come cataloged as metric oil seals or imperial sized oil seals. The seals can also be custom-made to match the bearings in new types of machinery. They are installed in practically every type of machine including vehicles, protecting all kinds of precision, precisely-fitted ball bearings, sleeve bearings, and roller bearings.

  • Highly resistant to both high and low temperatures

  • Silicone Oil Seals - Designed to absorb lubricants in order to lessen wear and friction, silicone rotary shafts also offer high thermal resistance and a large temperature range. But, they do not handle abrasions well or interact with oxidized oils.

  • Fluid side face The front-end face of the seal is called the nose. The nose is made of rubber and forms a gasket seal when compressed on the housing shoulder.

  • Material Code ISO 1629

  • The primary function of an oil seal is to create a barrier between the rotating or moving parts of a machine and prevent oil or other fluids from leaking out. This helps to ensure that the machinery operates smoothly and efficiently without any loss of lubrication or contamination of the surrounding environment. In addition to preventing leakage, oil seals also help to retain lubricant within the system, extending the life of the equipment.


  • When selecting an oil seal, it is important to consider factors such as the type of fluid being sealed, the temperature and pressure ranges, and the speed at which the shaft or piston will rotate. This will help ensure that the seal is compatible with the specific requirements of the application and will provide the necessary level of protection.

  • In addition to providing a reliable seal, the 40mm rubber gasket also helps to dampen vibrations and reduce noise, improving the overall performance and longevity of the equipment. Its durable construction ensures long-term reliability and minimizes the need for frequent maintenance or replacement.


  • Double metal cased

  • There may be a rubber '0' ring oil seal round the base of the distributor, or a paper gasket under the plate of the securing clamp. Remove either seal, clean away all dirt and oil, and fit the new one.

  • If this is not possible, you may be able to fit the lower retaining bolt into the upper mounting support, to hold the engine level. Or the gearbox may have to be jacked up and supported.

  • When it comes time to replace a cylinder head gasket, it is important to use high-quality materials and follow the manufacturer's specifications. Proper installation of a new gasket is crucial to ensure a tight seal and prevent any future leaks or issues. It is also recommended to have the engine thoroughly inspected by a professional mechanic to identify any underlying issues that may have caused the gasket to fail in the first place.
  • The quality and condition of spark plug wires significantly impact the performance of an engine. Worn or damaged wires can lead to misfires, reduced power output, and decreased fuel efficiency. Regular inspection and timely replacement of spark plug wires are essential for maintaining optimal engine health. A well-functioning set of wires ensures smooth idling, improved acceleration, and a more consistent overall driving experience.

  • One of the key benefits of the Oil Seal 20/34/7 is its ability to withstand high pressures and temperatures. This makes it an ideal choice for use in applications where these conditions are present, such as in heavy-duty machinery and equipment This makes it an ideal choice for use in applications where these conditions are present, such as in heavy-duty machinery and equipment This makes it an ideal choice for use in applications where these conditions are present, such as in heavy-duty machinery and equipment This makes it an ideal choice for use in applications where these conditions are present, such as in heavy-duty machinery and equipmentoil seal 20 34 7. The seal also offers excellent resistance to wear and tear, ensuring a long service life even under severe operating conditions.
  • The 'MGB' in the name does not denote any specific technical feature; rather, it is a model identifier used by NGK for their range of spark plugs. Each MGB spark plug is crafted with a unique combination of materials and design features to cater to different engine requirements. For instance, some models feature a copper core for efficient heat dissipation, while others utilize iridium or platinum for enhanced durability and improved fuel efficiency.

  • INTEGRATED OIL SEALS

  • It is important to regularly inspect the power steering oil seal for any signs of wear or damage. Common symptoms of a faulty power steering oil seal include power steering fluid leaks, difficulty turning the steering wheel, and a whining noise coming from the power steering pump. If any of these symptoms are present, it is important to have the power steering system inspected by a qualified technician to determine if the oil seal needs to be replaced.
  • Spark plugs, small components in the internal combustion engine, play a crucial role in vehicle performance. They are responsible for igniting the air/fuel mixture in the combustion chamber, which in turn powers the engine. Given their importance, it's not surprising that spark plugs have a cost associated with them, both financially and operationally. This article delves into the cost of spark plugs and its broader implications for vehicle maintenance.

  • Many seals come with a garter spring, found within the backside of the seal. It provides contracting pressure against the sealing surface. Making sure the spring seats correctly within the seal is an excellent first step.

  • After the oil seal has been installed, check for leaks. You can do this by applying pressure to the system and observing for any signs of a leak, such as fluid escaping from the area where the oil seal is installed. If a leak is present, you may need to remove the oil seal and start the installation process again.

  • Oil seals are typically made from a variety of materials, including rubber,PTFE (polytetrafluoroethylene), and various metals. Each material offers unique benefits depending on the specific application and operating conditions. For instance, rubber oil seals are well-suited for applications that require flexibility and resistance to high temperatures, while PTFE seals are renowned for their chemical resistance and low friction properties.
