Product Description
The 570057/B O-Ring is an authentic factory-original (OEM) replacement designed for the oil drain system of Royal Enfield UCE motorcycles. This rubber ring fits onto the Right Hand Side Crankcase Drain Cap (Sump Drain Cap), which houses the secondary suction filter.
Over time, this o-ring can become compressed, brittle, or torn due to engine heat and repeated oil changes, leading to persistent oil weeping or pressure loss. Replacing this seal during every engine oil service ensures a perfect, vacuum-tight closure, protecting your engine from contaminants and maintaining oil pressure. Manufactured from high-grade, heat-resistant synthetic rubber, it is built to survive the high-temperature environment of an air-cooled engine.
