Graco TSL Throat Seal Liquid

Product Overview

Graco TSL (Throat Seal Liquid) is a specially formulated lubricant designed to protect the internal components of airless paint sprayers, particularly the displacement rod and upper packings. It’s a clear, non-drying fluid that sits in the wet cup of the sprayer and acts as a barrier between the pump and the atmosphere.

Purpose & Applications

• Primary Purpose: Prevents dried paint or coatings from building up on the piston rod, which can damage packings and reduce sprayer performance.
• Applications:
  • Ideal for professional contractors using Graco airless sprayers.
  • Commonly used in residential, commercial, and industrial painting.
  • Compatible with larger sprayers like the GH Big Rig series, 190ES, 210ES, and other high-output models.
  • Not recommended for smaller DIY units like the X5, X7, or X9.

Key Features & Benefits

Instructions for Use

1. Before spraying, fill the pump’s wet cup with TSL until it covers the displacement rod.
2. Check regularly during use and refill as needed to maintain coverage.
3. After spraying, leave TSL in the wet cup to protect the rod during storage.
4. Do not mix with paint or other fluids--TSL is for external lubrication only.
