GRACO 16T531 – Scraper Cartridge Kit

GRACO 16T531 – Scraper Cartridge Kit

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.

This scraper cartridge is responsible for clearing residual material from the guns internal chamber area while maintaining a tight seal. Over time, plural-component materials can adhere to internal surfaces, causing drag, clogging, or inconsistent operation. Replacing the scraper cartridge restores proper function and supports consistent spray quality.

Use on Graco EP-series and related spray guns that list 16T531 in their parts breakdown. Always verify compatibility with your specific model.
