How do these filters perform and what are the build details?

Each cartridge is manufactured to OME-style specifications for consistent dimensions and media placement to support correct sealing and airflow. The filters use pleated media and rigid end caps to hold shape under service conditions; they are replacement parts rather than original-brand cartridges.

• Manufactured to OME standard and specification for dimensional accuracy.
• Pleated filtration media for surface area and dust-holding capacity.
• Rigid end caps and inner core to maintain structural integrity during service.
• Sold as inner plus outer cartridge pair for systems that require both elements.

How should I install and maintain the inner and outer cartridges?

Replace both cartridges at the same service interval or when either shows heavy contamination or damage. Clean the housing and inspect seals before seating the new filters, then follow torque and clamp instructions from the engine manufacturer to ensure proper sealing.

• Always remove debris from the filter housing before installation.
• Inspect gaskets and seals; replace if cracked or hardened.
• Seat inner filter first (where applicable), then install outer cartridge and secure housing.
• Follow your equipment’s service schedule for replacement intervals.
