Grommet for Oil Dipstick Tube - LU
Detroit Diesel

This elastomer grommet serves as a critical seal for the LU oil dipstick tube, preventing contaminants from entering the crankcase while allowing for easy access during oil checks. Its precise dimensions—height, inner, and outer diameters—ensure a snug fit that maintains a secure seal under vibration and thermal expansion. The flexible elastomer material absorbs shocks and resists cracking or deterioration over time, providing a long-lasting protective barrier. Proper sealing is essential to maintain oil integrity, prevent leaks, and reduce the risk of dirt or debris contamination. Installation quality directly impacts the longevity and effectiveness of this component. Source One Parts Center supplies this grommet, assuring you receive a high-quality part that meets rigorous standards for durability and fitment, helping to sustain your engine’s health and performance.
