- Another important benefit of the A7RTC spark plug is its long lifespan. This spark plug is made from high-quality materials that are designed to withstand the harsh conditions inside your engine. As a result, the A7RTC spark plug can last for a long time, providing reliable performance and ignition for your vehicle.
- The c15 valve cover gasket is specifically designed for use in Caterpillar C15 engines. These engines are commonly found in heavy-duty trucks, construction equipment, and other industrial applications. The valve cover gasket plays a crucial role in maintaining the proper functioning of the engine.

Oil Seals Enable Your Equipment to Operate Efficiently
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.
Proper installation of the 25x47x7 oil seal is essential to ensure its effectiveness. It is important to carefully clean and prepare the surfaces where the seal will be placed, as any dirt or debris can compromise the seal's ability to function properly. Additionally, the seal should be installed with the correct orientation and pressure to create a tight and secure seal.

Spring seals are the perfect solution when regular seals are unable to produce a leak-proof mating surface. They are the best substitute for sealing applications involving machinery as they are capable of resisting more heat and pressure than other types of seals.
Entry of dust and debris is one of the most common reasons oil seals fail. For instance, in high-pressure applications, even the smallest sediments can create a gap in the seal, causing the oil to leak and dirt to get in.
