Graco Throat Seal Liquid (TSL) extends throat packing life. Formulated to prevent paint from drying on the displacement rod, throat seal liquid extends the life of throat packings and the piston rod.
Graco TSL™ is clear in color and specially formulated so it will not impact the finish of oil or water-based coatings, even if it is accidentally dripped into the coating material.
Fill cup with TSL every time you spray to reduce paint adhesion on the rod. Do not use oil as a substitute for TSL
