- Our commitment to quality starts with sourcing only the best materials for our valve cover gaskets. We use materials that are resistant to heat, oil, and other harsh conditions commonly found in engines. This ensures that our gaskets can withstand the rigors of daily use and provide long-lasting performance.
- In the intricate world of mechanical engineering, oil seals play an indispensable role in ensuring the efficient and safe operation of various machines. The 40x52x7 oil seal, in particular, stands as a testament to the precision and importance of these seemingly small yet vital components.

The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
Oil seals operate by creating a tight barrier between two moving or stationary parts, such as a shaft and housing, to prevent oil from escaping and contaminants from entering the system. This is essential for maintaining the efficiency and performance of the machinery, as well as preventing potential safety hazards.
In order to use the oil seal reasonably, the following points should be paid attention to:

Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.

Significance of Quality Seals in Automotive Applications:
Oil seals, also known as rotary shaft seals, are designed to prevent oil leaks in rotating machinery by sealing the gap between a rotating shaft and a stationary housing. Proper installation of oil seals is essential to ensure a leak-free performance, which in turn helps to extend the life of the machinery. In this article, we will go over the steps for installing oil seals correctly.


A typical oil seal consists of three common parts: an outer ring, the sealing element, and a spring. The exterior metal ring component provides strength and rigidity to the oil seal in the bore or recessed groove. Attached to that ring is the sealing element. This flexible interior component of the oil seal, the O-ring, prevents any fluid leaks between the shaft and housing. A spring ensures the constant pressure that deforms the O-ring, creating a reliable seal while maintaining radial force on the shaft.
