Product Details

This genuine OEM inlet seal is designed for the fluid-entry section of Graco airless sprayers. It creates a secure and leak-resistant seal at the pump inlet to maintain proper pressure and prevent air intrusion. Replacing a worn inlet seal helps restore consistent spray performance and protects internal pump components from unnecessary wear.

Key Features

Installation Notes

• Always depressurize the sprayer and disconnect power before servicing.
