Volvo Mack DPF Gasket 14.25" (Pack of 2) – D11 D13 MP7 MP8 Aftertreatment Seal – Replaces 21570880

Ensure a professional, leak-free seal in your aftertreatment system with this 2-pack of premium 14.25" Volvo Mack DPF Gaskets. Specifically engineered for Volvo D11/D13 and Mack MP7/MP8 engines, these high-temperature gaskets are critical for sealing the larger DPF canisters and DOC units within the 1-Box system. In the corrosive, salt-heavy environments of the Midwest, exhaust hardware is a frequent failure point; using a fresh Volvo Mack DPF Gasket is the only way to prevent "soot-tracking" and maintain the backpressure levels required for proper engine performance. This set is a direct replacement for OEM 21570880 and works in conjunction with Skyline DPF VN1212.

Industrial-Grade Thermal Protection: The Volvo Mack DPF Gasket Advantage

This 14.25" Volvo Mack DPF Gasket is manufactured from high-grade, heat-resistant materials that won't degrade or blow out during the intense thermal stress of an active DPF regeneration. Designed for use with OEM Clamp 21570880, these gaskets provide the exact outer diameter (OD) needed for a precision fit on standard Volvo and Mack 1-Box assemblies. Note: Because these are "crush-style" seals, they must be replaced every time a clamp is loosened for cleaning or inspection. This convenient 2-pack ensures you have the necessary seals for both the inlet and outlet sides of your aftertreatment canister, saving you time and preventing repeat repairs.

As we continue to build the largest inventory of commercial truck parts in Illinois, we prioritize emission-critical components that meet or exceed OEM quality. These Volvo Mack DPF Gaskets are essential for owner-operators and fleet mechanics performing routine maintenance on modern Volvo VNL and Mack Anthem rigs. By maintaining a 100% airtight seal, you protect your turbocharger and ensure your truck stays fully compliant with EPA standards. Don't risk a "check engine" light due to a recycled seal—upgrade to a professional-grade Volvo Mack DPF Gasket set today.
