Valve Stem Washers with Parallel Faces
Detroit Diesel

These steel valve stem washers play a critical role in maintaining a secure seal within the valve assembly. With their precisely engineered parallel faces, they ensure proper alignment and prevent leaks under the high-pressure conditions typical in heavy-duty engines. The 0.02-inch thickness provides just enough resilience to accommodate thermal expansion and contraction, reducing wear over time. The inner diameter of 0.61 inches fits snugly onto the valve stem, while the outer diameter of 1.36 inches ensures a firm contact surface, preventing any unwanted movement. Their sturdy steel construction guarantees durability and resistance to corrosion, which is essential in the demanding environment of diesel engine operation. Properly functioning washers contribute to optimal engine performance, reduced emissions, and longer service intervals. Source One Parts Center offers these washers as a reliable source for genuine heavy-duty components, ensuring your engine's valve train remains sealed and efficient over its service life.
