CAT® NATURAL GAS FUEL FILTERS
These high-quality filters protect your engine from the dirt and liquids that are found in natural gas fuel. Here is why that is an important advantage: Carried under pressure, those contaminants (small particles of sand, clay, iron, pipe scale, water and oils) can cause premature component wear. Therefore, superb filtration is key for engine longevity and performance.

The pleated media in Caterpillar Natural Gas Fuel Filters more than triples the filtration area, resulting in the following benefits:
  • Lower differential pressure
  • Better efficiency
  • High dirt-holding capacity
  • Longer change intervals

Multiple layers deliver efficient filtration, with unique attributes in each layer:
  • Pleated media layer holds solid contaminates, such as sand and pipe scale
  • Draining layer removes liquids, such as water and oil
  • Support layer adds strength against high pressures and extreme temperatures

Replacement components available for ordering include:
  • Natural gas filter options (whether you need a G3612 fuel filter, a 3516B fuel filter or another type of filter)
  • A natural gas filter element option
  • Natural gas filter cartridge options
