Heavy duty Filters

Precision Spiral Roving for Maximum Stability (Example: CAT 1R-1808 to GQP GEO-1808):

Most fleets use the CAT 1R-1808 because it is the most common filter in the industry and a long-standing OEM benchmark. The GQP GEO-1808 builds on that foundation with a precision, close-placement spiral-roving design that locks the media firmly in place.

The traditional 1R-1808 positions the roving further from the pleats, which can allow pleat movement during pressure spikes or cold starts. GQP places the roving directly against the pleats for consistent stability and superior reinforcement.

Key performance advantages of the GQP GEO-1808:

• Stronger structural integrity with reinforced pleat geometry
• Zero pleat distortion under hydraulic stress
• Higher resistance to collapse during cold-start pressure spikes
• Accurate micron performance during high-flow and heavy-load cycles
• Cleaner oil and stable flow throughout the service interval

This closer roving pattern secures the media, prevents channeling, eliminates drift and protects the clean side from contaminant migration.

No distortion. No channeling. No compromises.Only cleaner oil, stable flow and repeatable OEM-grade protection that surpasses standard OEM filters and traditional aftermarket competitors.

The 1R-1808 used by Caterpillar is also offered by Cummins as Fleetguard LF691A, by Donaldson as P551808 and by Baldwin as B7299. Across all comparisons, GQP GEO-1808 stands out as the clear leader in both price and quality.

Molded End Caps & Core for Perfect Clean-Side Sealing

Unlike stamped metal end caps & metal core commonly seen in standard Non-OEM filters, GQP uses precision-molded end caps & core that fully isolate the clean and dirty sides.

This provides:

• A perfect clean-side seal with no cross-contamination
• Better spacing between the end cap and nylon core
• Smoother oil flow under load
• More stable performance during pressure fluctuations
• Longer system life through reduced component wear

Engineered for Modern High-Pressure Systems

Today’s Tier 3 to Tier 5 engines and high-pressure hydraulic systems create extreme filtration demands. GQP Filters are designed to handle:

• High-pressure hydraulic circuits
• Variable-flow oil systems
• Extreme temperature swings
• Cold-start surges
• High-hour and large displacement machines
• Construction, mining, forestry, oilfield and industrial environments

From excavators and haul trucks to dozers, telehandlers and generators, GQP provides the OEM-grade protection your equipment depends on.
