- It is important to be able to recognize the signs of a bad spark plug so that you can replace it before it causes serious damage to your dirt bike's engine. Some common signs of a bad spark plug include difficulty starting the engine, rough idling, poor acceleration, and decreased fuel efficiency. If you notice any of these symptoms, it is a good idea to inspect your spark plug and replace it if necessary.
There are various sizes of industrial and ordinary oil seals, ranging from 0 to 33cm (13in). These varieties are also designed for different temperatures. As long as your seal matches the original equipment it’s intended for, you can be sure your machine will perform at its best. For further guidance and information regarding oil seals, don’t hesitate to contact our knowledgeable team. We are always available to assist you with your bearing, seal and gasket needs.
There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.
In conclusion, spark plugs are a critical component of any internal combustion engine, as they are responsible for igniting the air-fuel mixture and powering the vehicle. Regular maintenance and replacement of spark plugs are essential to ensure optimal engine performance and efficiency. By choosing the right type of spark plugs and properly installing them, vehicle owners can enjoy a smoother and more reliable driving experience.

Material: There are several material options. Nitrile (Blank), Viton (V), Silicone (S), EPDM (E), Carboxylated Nitrile (X), HNBR (H), Polyacrylate (P), and Teflon (T).
Updates in oil seals

silicone rubber gasket. This resistance makes them suitable for use in industries where exposure to harsh chemicals is common, such as in the chemical processing, pharmaceutical, and food and beverage industries. The inert nature of silicone rubber also prevents it from reacting with the substances it comes into contact with, ensuring a long-lasting and reliable seal.

Pour-point depressants: This additive has nothing to do the actual pouring of your oil. In fact, pour-point depressants help prevent the wax particles in the oil from hardening in cold conditions. As a result, the motor oil flows freely even in low, cold temperatures and the engine doesn’t need to work any harder to pump it.
