    The mating surfaces of the head or block must be perfectly clean, flat and smooth.

    The allowable total eccentricity is the maximum total eccentricity at which the sealing edge can accommodate shaft rotation and retain adequate sealing performance. The oil seal's allowable total eccentricity is affected by the design of the oil seal, the accuracy of the shaft, and the operating conditions.

  • PTFE Oil Seals – Are a relatively new oil seal, the use of polytetrafluoroethylene means they can withstand dry and unlubricated operations. They have a massive thermal range spanning from -130°C to more than 200°C and a strong resistance to chemicals, they are the future of rotary shaft seals.
    •  In the intricate machinery of modern industry, the rubber U-channel gasket plays a crucial, albeit often overlooked, role. These unassuming components are designed to provide a reliable seal between two surfaces, preventing liquid or gaseous materials from escaping or entering a system where they are not wanted. Their simple 'U' shape belies their importance in ensuring the smooth functioning and safety of various industrial processes.

     

    Acrylonitrile-buta-diene natural rubber (NBR - Nitrile)
    Manufactured from high-quality elastomers, rubber U-channel gaskets boast exceptional elasticity and resilience, enabling them to conform to the shapes of the mating surfaces while withstanding the pressure differences that arise in industrial environments. This adaptability is further enhanced by the material's inherent ability to resist degradation from oils, chemicals, and temperature fluctuations—a vital attribute given the diverse conditions under which they operate.
    The primary function of the engine oil seal is to create a tight seal between the engine block and the rotating shaft, such as the camshaft or crankshaft. By doing so, it prevents oil from leaking out of the engine and also prevents dirt and debris from entering the engine. This is particularly important because oil is essential for lubricating the engine's moving parts, reducing friction, and dissipating heat. Without an effective oil seal, the engine could overheat, leading to severe damage and costly repairs.

    Because synthetic motor oil can cost two to four times more than regular oil, talk to your technician about whether it’s the right oil for your car. If you live in a climate with super cold winters or very hot summers, or use your vehicle for towing or hauling, synthetic oil may be the best type of oil for your vehicle. Older engines could also benefit from synthetic oil, as it can help prevent harmful sludge build-up that some older engines seem to be prone to.

     Spark plug wires are a critical component in the ignition system of your car. They transmit the high voltage electrical current from the ignition coil to the spark plugs, which then ignite the air-fuel mixture in the combustion chamber. Over time, these wires can become worn or damaged, leading to poor engine performance and potentially even engine damage. Therefore, it is essential to test your spark plug wires regularly to ensure they are in good condition.

    Depending on the application, premium lip materials may need to be used, such as Ethylene-acrylic (Varmac®). This material features good abrasion and dry running capabilities, higher heat capabilities than nitrile and polyacrylate, and better low-temperature performance than polyacrylate.
