This check valve kit fits the Tilton cooler pump. If your pump takes forever to prime, the check valve may be leaking.
Note: This kit uses Viton (fluorocarbon) rubber. Our Part No. 1239 comes with Buna-N (Nitrile) rubber components. Buna-N is recommended for use with oil and water. The Viton seals in this kit are more suitable for corrosive liquids like fuel or alcohol.
