ROUND OIL FILTER

What they are: These are filtration elements designed to remove contaminants from an engine’s lubricating oil. They are crucial for maintaining engine health and longevity by preventing abrasive particles and sludge from circulating and causing wear.

Key Features and Characteristics:

• Shape: Round/Cylindrical with a hollow core. This shape allows them to be fitted into a filter housing or spin-on canister.
• Filter Media: The prominent yellow, pleated material is the filter media. This is typically made from:
  • Pleated Paper or Cellulose: This is the most common material, designed with micro-pores to trap particles while allowing oil to flow through. The pleats maximize the surface area for filtration within the compact cylindrical form.
