Details
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.
