Product Details
Ventilation Performance
This genuine Cummins OEM crankcase breather efficiently manages positive crankcase ventilation (PCV) by filtering oil aerosols and directing clean gases back to the intake or atmosphere (depending on system design). Built to exact factory standards, it ensures optimal pressure balance, minimizes oil contamination, and supports compliance with emissions regulations in heavy-duty operations.
Volgen Power delivers authentic Cummins components for reliable, long-lasting crankcase ventilation without compromises.
