🔧 Technical Insights
Unlike standard O-rings, this rectangular ring seal offers a broader surface contact area. As a result, it enhances sealing effectiveness, especially in applications with thermal cycling or vibration.
In addition, the material compound used offers strong resistance to swelling, compression set, and chemical breakdown. Therefore, even after long use, it maintains its shape and performance—reducing maintenance needs.
Because it follows Cummins genuine parts tolerances, installation is quick and precise.
