About the Bosch Workshop Oil Filter Line

The Workshop Oil Filter line by Bosch is designed to meet the demands of professional automotive service environments. These filters focus on durability and consistent filtration performance, making them suitable for a variety of engine types. The 72143WS model fits within this line, offering features such as a spin-on design and robust valve systems to maintain engine oil integrity during operation.

Detailed Product Description

The Bosch 72143WS oil filter uses cellulose paper as its filtering media, providing a micron rating of 30 to effectively trap contaminants while maintaining proper oil flow. Its spin-on design with a 3/4-16 thread size allows for straightforward installation and removal. The inclusion of an anti-drain back valve prevents oil from draining out of the filter when the engine is off, reducing dry starts. Additionally, the bypass relief valve ensures oil continues to circulate even if the filter becomes clogged, protecting the engine from oil starvation. The nitrile gasket material offers a secure seal to prevent leaks under various operating conditions. With a burst pressure rating of 200 PSI, this filter is built to withstand the pressures encountered in typical engine oil systems.
