Despite being incredibly flexible, silicone has some significant drawbacks. The toughness, resistance to wear, and abrasion of many silicone compounds are poor. If you seriously need an oil seal material with better strength and resistance to high temperature, the perfect option is Viton.
In the vast expanse of technological advancements, few components remain as universally integral as the humble spark plug wire. These cables, often underappreciated, serve as the lifeline between an engine's electrical system and its heart—the combustion chamber where tiny sparks ignite a force powerful enough to propel machines forward. Yet, in the shadow of modern innovation, these wires have transcended their original purpose, becoming metaphors for connectivity and inspiration in diverse fields.The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.
It is important to choose the right type of oil seal for a given application, as it may need to address specific operational concerns such as:
Most effective sealing is obtained with optimum shaft surface finishes. The sealing efficiency is affected by the direction of the finish tool marks and the spiral lead. Best sealing results are obtained with polished or ground shafts with concentric (no spiral lead) finish marks. If you must use shafts with spiral finish leads, they should lead toward the fluid when the shaft rotates.
In general, oil seals should be selected in the order of priority indicated in Table 1.

Choosing and using the proper sealing devices within oil and gas applications can be vital when preventing dirt, dust, water, and other debris from potentially getting inside and contaminating products.
6. Demolding Once the gasket has cured, it is removed from the mold and inspected for any defects or inconsistencies.
