Graco Throat Seal Liquid (TSL) Fluid

Graco Throat Seal Liquid (TSL)

Graco Throat Seal Liquid (TSL) is a vital, proprietary lubricant designed to keep your airless spray machine’s pump operating at peak performance. It works by creating a protective barrier that prevents paint and various coatings from drying on the displacement rod and packings. Regular application of TSL is one of the most critical maintenance steps to ensure your equipment runs smoothly and stays in top condition.

Graco manufactures some of the industry’s most durable pump lowers, but they are considered wear items that require consistent care. TSL is specifically formulated to protect these components from unnecessary friction and material buildup, which helps you avoid costly repairs and unexpected downtime. For maximum protection, it is recommended to apply TSL at the start of every shift.

Key Benefits

• Extends Pump Life: Significantly reduces wear and tear on internal components and packings, keeping the pump in top shape for longer.
• Prevents Paint Buildup: Stops coatings from drying onto the displacement rod, which prevents the friction that leads to packing failure.
• Early Wear Indicator: Acts as a diagnostic tool; if the oil shows signs of pigment, it indicates packing wear, allowing you to perform maintenance before major damage occurs.
• Maximizes Productivity: By preventing downtime and ensuring smooth operation, TSL helps you stay on the job longer without interruptions.
• Universal Compatibility: Approved for use in all airless pumps to protect lowers from corrosion and wear.
