- One of the key advantages of iridium spark plugs is their exceptional ability to withstand extreme temperatures. Iridium, a rare and highly conductive metal, has a melting point that is significantly higher than that of traditional platinum or nickel alloy spark plugs. This means that iridium spark plugs can handle the intense heat generated by modern engines without sacrificing performance or longevity.
- In the world of industrial machinery and equipment, the significance of a seemingly minor component like the SC oil seal cannot be overstated. An SC oil seal is a mechanical gasket that fills the space between a shaft and a bearing housing or between two mating surfaces, preventing lubricant from leaking out and contaminants from entering in. This article delves into the importance of SC oil seals in various industrial applications.

- Crafted from durable elastomers, the small rubber gasket is designed to fill the gap between two surfaces, providing an airtight and watertight seal. Its elasticity allows it to conform to irregularities in mating surfaces, ensuring a continuous barrier against fluid or gaseous leakage. In essence, the small rubber gasket is the guard that stands sentinel at the threshold of potential failure, preventing catastrophic consequences such as oil spills or refrigerant loss.
The depth of the bonded seal can be less and the space between the bore and the outside diameter can be changed for ease of fitting. The bonding of rubber to metal is an important factor to be considered in the manufacture of such seals and should be considered carefully, since failure of the bond will cause the seal to fail. The metal case of the oil seal is usually made from mild steel of deep drawing quality which enables blanking, punching, stamping of the steel to the required dimensions.

One way to recognize an improperly installed seal is by checking whether or not there is uneven shearing of the rubber after use. If this is evident, adjust by aligning the installation tools properly before pressing the seal into place.
WHAT ARE THE TYPES OF OIL SEALS?
Remove the distributor cap . Before removing the distributor (See Removing and refitting the distributor ), mark the position of the rotor arm so that you can refit it just as it was.

WHAT ARE THE TYPES OF OIL SEALS?
Once you have selected the most suitable seal available, considering the environment, temperature, shaft speed, pressure, lubrication availability, as well as the size, of course, the seal should be stored adequately and then fitted properly. Here are a few suggestions that could help:-
