A patent for an oil seal was filed by Nelson Thomas Edward on August 12, 1937, and published a year later. There were two purposes described. The device was to provide an oil seal between a fixed housing and a rotating part. The seal is described as
One of the key advantages of the BR9ES Spark Plug is its ability to ignite the combustion process more efficiently than conventional spark plugs. This is achieved through the use of a proprietary ceramic insulation material that withstands high temperatures and provides a more consistent spark across the entire electrode surface. As a result, engines equipped with BR9ES Spark Plugs experience improved power output, reduced fuel consumption, and lower emissions.In addition to selecting the right type of oil seal, it is essential to consider the operating conditions of the equipment. Factors such as temperature, pressure, and speed can impact the performance and longevity of the seal. Choosing a seal that is rated for the specific operating conditions will help ensure reliable sealing and extended service life.
