The Drain Valve O-Ring Seal creates a secure barrier that prevents lubricating oil from escaping while also thwarting the entry of contaminants, designed to fit into specific grooves or cavities and create a tight seal when compressed between two mating surfaces, reducing friction and wear on the drain valve and engine oil pan.Attributes:• Seals effectively to prevent oil leakage.• Helps maintain optimal lubrication levels.• Resistant to temperature variations. Applications: The Drain Valve O-Ring Seal fitted on the drain valve of the engine oil pan forms a tight barrier to prevent oil from escaping.
