215090 Cummins O-Ring Seal
- Application : It is primarily used as a cylinder liner/sleeve crevice seal. Positioned along the cylinder liner, it forms a high-pressure seal to contain combustion gases and keep engine fluids (coolant and oil) separated.
- Engine Compatibility : Commonly fits legacy heavy-duty 14-liter and 855-cubic-inch Cummins engine families, including the N14 (CELECT, CELECT Plus, Mechanical), NH855, NT855, G855, and QSN14 series.
- Design & Material : Made of high-grade elastomeric synthetic rubber (such as Nitrile/NBR), featuring a rectangular cross-section rather than a standard round O-ring profile. This shape provides broader surface contact to resist extreme temperatures, pressure fluctuations, and engine vibrations inside the block.
- Part Interchanges : Replaces or supersedes older part numbers such as 183056.
The Cummins 215090 O-ring seal (also known as a rectangular ring seal or crevice seal) is a critical engine sealing component designed specifically for heavy-duty diesel engines.
