About Durafit

Designed to Fit.

DuraFit replacement DPFs ease installation and get your equipment back to work quickly. Each DPF unit is specifically designed to fit your application – ensuring an exact replacement for your OEM diesel particulate filter. Each DuraFit DPF comes with required gaskets included with the DPF, eliminating potential delays from errors with separate or multiple part numbers.

Built to Last.

Your equipment uptime and reliability is DuraFit's primary concern. That's why replacement DPF units from DuraFit offer enhancements over many OEM DPFs that help improve durability and extend service life. DuraFit puts their DPFs through some of the most stringent testing and verification processes – ensuring they meet or exceed OEM performance requirements and will continue to provide exceptional longevity in your heavy-duty diesel equipment.

Although premium DuraFit OEM replacement DPFs may cost slightly more up front, they can produce long-term savings. When compared with the cost of lost productivity or repeated DPF replacement, paying a little more for the enhancements inside DuraFit DPFs is low-cost insurance that pays dividends in the long-term productivity of your equipment.
