After drying, if you notice any dull spots or if the surface seems a bit dry, apply a thin layer of cooking oil (such as vegetable oil or flaxseed oil) to the inside of the cookware. Wipe off excess oil with a paper towel to ensure a light coating. If possible, place it back over the heat for a few minutes to allow the oil to bond with the cast iron, enhancing the seasoning.



This type of oil seal can withstand only low speed and friction. It is recommended in places where thick fluid or grease is to be sealed. This is not recommended for difficult applications.

Polyacrylate oil seals are a perfect compromise between quality and cost. They perform well with high temperatures and chemicals, but not as well as Viton oil seals. Polyacrylate has a temperature range of -25 degrees Fahrenheit to 300 degrees Fahrenheit. Due to their outstanding resistance to hot oil and oxidation, they are commonly used in automobile transmissions and hoses; however, they are also used for shaft seals, gaskets, and o-rings.

In conclusion, U-shaped silicone gaskets, white rubber gasket sheets, and waterproof rubber gaskets offer versatile and effective sealing solutions for a wide range of industrial and commercial applications. Understanding the advantages and applications of these gaskets is crucial for selecting the appropriate sealing components to ensure protection, reliability, and longevity in various systems and equipment.


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 this an auxiliary lip is provided along with the regular sealing lip. The additional dust lip protects the main sealing lip against dust and other fine solid contaminants and therefore this type is recommended for use in polluted environments. To achieve a long lifetime a suitable lubricant between the two sealing lips should be applied.
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.
An overview of the different standard types of oil seals and their main characteristics is shown below.
Use a flat paint scraper, or the smooth side of an old hacksaw blade, to remove very carefully all traces of carbon and old gasket from both faces.
