A screw plug washer acts as a sealing element seated between a threaded plug and its mating surface on the pump housing. Its role is to create a leak-free barrier at service or drain ports, preventing fluid from escaping under pressure or during operation. When this washer becomes compressed, cracked, or damaged, it can allow oil or fluid to seep past the plug, leading to contamination, fluid loss, and potential damage to internal pump components if left unchecked.
