The simplest way is to know either the preferred manufacturers part number, the overall sizes of shaft diameter, housing diameter and bore depth, or use our brochure to establish the M Barnwell Services ordering reference. Many of the old traditional names of seal manufacturers have either changed or disappeared in this age of “acquisitions”. If no longer available, we will advise you and offer a suitable alternative seal, from stock whenever possible. If your concern is getting the right seals for the job, you will need to know something about the application as well as the overall sizes. If you have any doubts – contact us, we will help in your seal selection.
contaminated with moisture or any other particle. But the same oil will only last for a month at 212 degrees Fahrenheit if it’s contaminated with little water. This is why the function of an oil seal is very evident whenever it’s used.

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.

c15 valve cover gasket. If dirt or debris were to enter the engine, it could cause damage to sensitive components such as the valves and camshafts. By maintaining a tight seal with the valve cover gasket, you can keep your engine clean and free from contaminants.
Silicone and rubber gaskets offer numerous advantages, including resistance to temperature extremes, chemicals, and environmental factors. Their flexibility and resilience allow for effective sealing in dynamic and challenging conditions. Additionally, these gaskets provide vibration dampening, noise reduction, and electrical insulation, making them valuable components in a wide range of industrial and commercial applications.
