  • ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.

  • In the realm of automotive technology, the significance of spark plugs cannot be overstated. These tiny components play a crucial role in igniting the combustion process within an engine's cylinders, thereby propelling a vehicle forward. Among the various types of spark plugs available, platinum spark plugs stand out for their exceptional performance and durability.
  • Spark plug wires, often overlooked in the intricate machinery of an engine, play a pivotal role in ensuring smooth and efficient performance. In particular, 7mm spark plug wires have garnered attention for their superior conductivity and durability. This article delves into the importance of these wires and how they contribute to the overall functionality of an engine.
  • Oil Seals From Global O-Ring and Seal

  • Overall, PTFE oil seals are a reliable and durable sealing solution for a wide range of industrial applications. Their superior chemical resistance, low friction properties, and ability to withstand harsh operating conditions make them a popular choice for engineers and maintenance professionals looking to improve the performance and reliability of their equipment.

  • It is essential to regularly check and replace spark plugs as needed to ensure the engine runs smoothly and efficiently. Over time, spark plugs can wear out due to the intense heat and pressure inside the engine cylinders. Worn-out spark plugs can lead to misfires, poor fuel economy, and even engine damage if left unattended.


  • Before installing the oil seal, it is important to lubricate it to reduce friction and prevent damage during installation. A silicone-based lubricant is recommended for most applications. If the oil seal is to be installed in a high-temperature or high-pressure environment, a more specialized lubricant may be required.

  • The importance of the wheel hub oil seal cannot be overstated, as it plays a crucial role in maintaining the overall performance and safety of a vehicle. A faulty or damaged oil seal can result in reduced fuel efficiency, increased noise and vibration, and ultimately, bearing failure. This can lead to costly repairs and potentially even a dangerous situation on the road.
  • When it comes to vehicle maintenance, one often overlooked component is the shock absorber oil seal. These seemingly insignificant parts play a crucial role in ensuring a smooth and safe driving experience. A damaged or worn-out oil seal can lead to oil leaks, compromising the performance of your car's shock absorbers, and ultimately, your overall driving comfort.
  • Shaft Surface Finishing

  • Car engine oil seals are essential components that prevent oil leaks and maintain proper lubrication within the engine. They play a crucial role in preserving the integrity and efficiency of the engine, contributing to its overall performance and longevity. High-quality engine oil seals are designed to withstand the demanding conditions of automotive operation, ensuring reliable sealing solutions for critical engine components.

  • In the realm of industrial manufacturing, sealing solutions are paramount. Custom molded gaskets, often overlooked as a simple component, play a crucial role in maintaining the integrity and efficiency of equipment and systems. These precision-engineered seals are specifically designed to fit the unique contours and requirements of various applications, ensuring a perfect seal every time.
  • Polyurethane 

  • In the automotive industry, PU oil seals are commonly used in engine compartments, transmission systems, and hydraulic components. Their robustness and ability to function under high-temperature and high-pressure conditions make them ideal for these applications. Similarly, in the manufacturing sector, they are vital in pumps, compressors, and other machinery where oil leakage can lead to downtime and costly maintenance.
  • Several variables must be considered when selecting oil seals. The physical dimensions and materials will vary depending on the environment of use. In addition, oil seals must remain lightweight, compact, and exhibit high self-lubrication performance.

  • In conclusion, the humble 12x22x5 oil seal might appear as a mere afterthought in the grand scheme of mechanical design. However, its significance cannot be overstated—it stands as a testament to the idea that even the smallest components can have the most profound impact on an engine's health and longevity. With a mere 5% tolerance rate, it epitomizes the engineering principle that precision equals perfection. As engineers continue to push the boundaries of what machines can do, components like the 12x22x5 oil seal will remain silent guardians, ensuring that the heart of those machines continues to beat strongly and efficiently.
  • The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth, or use our brochure to establish the M Barnwell Services ordering reference. Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.

  • Silver spark plugs are a less common type of spark plug that is often used in racing and high-performance applications. They have excellent conductivity and heat transfer properties, making them ideal for engines that operate at high temperatures. Silver spark plugs are more expensive than other types but offer superior performance in extreme conditions.
  • How to Choose the Right Oil Seal

  • Pressure: As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.
  • In the intricate machinery of modern industry and daily life, one unsung hero quietly safeguards against leaks, vibrations, and environmental contaminants the rubber gasket. This humble component, often a mere afterthought in the grand scheme of things, is an essential part of countless applications where sealing is paramount.
  • A spark plug is a simple device with a threaded shell that fits into the cylinder head of an engine. It has a central electrode and a side electrode, separated by a small gap. When voltage from the ignition system jumps this gap, it creates a spark, which ignites the compressed fuel-air mixture inside the combustion chamber. This controlled explosion pushes the piston down, converting chemical energy into mechanical energy, driving the vehicle or appliance forward.
  • The head gasket and valve cover gasket are critical components in the engine's sealing system. The head gasket seals the cylinder head to the engine block, while the valve cover gasket seals the valve cover to the cylinder head. Both gaskets play pivotal roles in maintaining the integrity and functionality of the engine, preventing oil leaks and ensuring the proper sealing of the combustion chamber.

  • Most standard oil seals have to comply with the DIN 3760 and ISO 6194 standards. Different standard types of oil seals are available that comply with these requirements.
