Graco 116553 Dielectric Grease Lubricant ES Gun

Graco 116553 – Dielectric Grease for ES Guns

The Graco 116553 Dielectric Grease is a genuine OEM lubricant and insulating grease designed specifically for electrostatic (ES) spray guns and compatible fluid‑handling systems. It helps maintain smooth operation, reliable sealing, and electrical insulation where required.

Key Features & Purpose

• Electrostatic‑compatible grease: dielectric (non‑conductive) grease suitable for ES guns.
• Lubrication & protection: recommended for power‑supply o‑rings, certain fluid‑needle parts and fluid fittings — to ensure smooth movement, prevent wear, and avoid leakage.
• OEM quality: manufactured by Graco to match original specifications, ensuring correct chemical composition and safe use with Graco ES equipment.
• Maintenance‑ready: ideal for gun assembly, rebuilds, or regular maintenance to preserve performance, prevent seal deterioration, and maintain spray quality.

Compatible Guns / Applications

• Graco ES (electrostatic) spray guns — guns whose parts list includes 116553 as the dielectric grease accessory.
• Any fluid‑handling or coating‑spray systems from Graco using electrostatic technology and requiring dielectric lubrication for internal seals and fittings.
• Maintenance, rebuild or service applications — whenever the gun or system manual recommends using dielectric grease for o‑rings, seals, fluid needles, or power‑supply interfaces.

Note: Always check your gun’s manual or exploded‑view parts diagram to confirm that 116553 is the correct grease for your model before applying. Using the wrong type of grease may impair sealing or electrical performance.

Why Use Graco 116553?

• Ensures proper lubrication and reduces wear on fluid‑path components and seals.
• Provides dielectric insulation — vital for safe and effective operation of ES guns under high-voltage or charged spray conditions.
• OEM‑specified grease — compatibility and reliability are maintained compared with generic or wrong-type lubricants.
• Simple maintenance upgrade — helps maintain spray quality and extends the life of seals, o‑rings and internal components.
