In the world of heavy-duty truck maintenance, the smallest components often prevent the biggest failures. The VG1246010031 O-shaped sealing ring is a critical sealing element for the wet cylinder liners of Sinotruk HOWO trucks. Positioned at the bottom of the liner, its job is to prevent coolant from contaminating your engine oil—a failure that can lead to catastrophic engine seizure.
As an experienced provider of HOWO parts, we ensure that our VG1246010031 rings are manufactured from high-grade fluorinated rubber (FKM). Unlike standard nitrile rings, these are designed to withstand the constant thermal cycling and chemical exposure found in WD615 and D12 engine blocks.

Why "Genuine" Matters for Sealing Rings?
-
Thermal Stability: Aftermarket rings often harden and crack within 6 months. Our HOWO parts maintain elasticity under extreme temperatures.
-
Precision Fit: A deviation of even 0.1mm can cause a slow leak. These rings are molded to exact Sinotruk factory tolerances.
-
Chemical Resistance: Specifically treated to resist the additives found in modern heavy-duty coolants.
