Auto spark plugs are critical components in the ignition systems of internal combustion engines in vehicles. These plugs play a pivotal role in igniting the air-fuel mixture within the engine cylinders, initiating the combustion process that powers the vehicle. High-quality auto spark plugs are essential for ensuring efficient fuel combustion, optimal engine performance, and reduced emissions, directly impacting the overall efficiency and environmental impact of the vehicle.

Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.
Our standard and custom rubber oil seals can match the increasingly demanding applications of any industry.
Seals perform much better and longer when they are continuously lubricated with an oil that has the correct viscosity for the application and that is compatible with the seal lip elastomer material. The consideration of seal incompatibility, particularly with certain additives and some synthetic lubricants, should not be ignored, but unfortunately very often is.
Lubricant Amount - Seals will always perform best when lubricated, however in some machines there are more likely to be dry spells. For these cases, selecting a leather or PTFE seal will be beneficial, as both can operate with less lubrication than others.

Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.

Oil seals are often called grease, fluid, or dirt seals. These seals close spaces between stationary and moving components in mechanical equipment. Oil seals are designed to prevent the escape of lubricant. They also block contaminants from entering machinery. This is especially important in severe environments where heat and foreign objects may be frequently present. They also prevent the mixing of different mediums like lubricating oil and water.
