🔧 Technical Insights
This gasket is precision-molded from a rubber composite that withstands the heat and pressure found in the top-end of diesel engines. Thanks to its flexibility, it conforms to surface irregularities, delivering a tight, even seal. Over time, it resists hardening and shrinking, which are common issues with lower-quality alternatives.
Moreover, since it meets Cummins parts OEM specifications, you can count on consistent fit and function within any engine using DCEC parts. The reinforced edges also help prevent blowouts and oil seepage under vibration.
