The GRACO 16T531 Scraper Cartridge Kit is a genuine OEM replacement designed to restore proper sealing and cleaning function inside select Graco EP-series spray guns. This kit helps maintain smooth operation by removing internal material buildup and ensuring the purge rod and front-end components move freely during spray cycles.
Key Features
- OEM scraper cartridge assembly engineered for EP-series and plural-component spray guns

Replacing the scraper cartridge restores proper function and supports consistent spray quality.
