CAT® PLUNGER-RELI Top Seller including Peterbilt and Kenworth modelsThe CAT PLUNGER RELI is a critical component in the oil filter and oil cooler systems of many Caterpillar engines. It functions as a relief valve plunger that remains closed under normal conditions but opens when filters become clogged, allowing oil to bypass and maintain continuous engine lubrication. This prevents pressure buildup and protects engine components by ensuring consistent oil flow even during filter blockages.
