Impact part 805-439 is a grommet used to protect and seal wires, hoses, or cables passing through panels and housings on compatible sprayers. This rubber grommet prevents chafing and abrasion damage, while also blocking dust, moisture, and debris from entering the enclosure. A cracked, dry-rotted, or missing grommet can lead to wire damage, shorts, and contamination of internal components. Replacing the grommet restores proper cable protection and environmental sealing on multiple Impact models.

The 805-439 Grommet is a flexible rubber component designed to fit into panel openings where wires, cables, or hoses pass through. It provides a protective cushion that prevents sharp metal edges from cutting or abrading the insulation of electrical wires or the outer layer of fluid hoses.
In addition to abrasion protection, the grommet creates a seal that helps keep dust, dirt, moisture, and chemical overspray from entering the sprayer's internal compartments. Over time, rubber grommets can dry out, crack, or become brittle due to exposure to heat, chemicals, and age. A deteriorated or missing grommet can lead to wire chafing, electrical shorts, corrosion, and contamination of sensitive components. Replacing worn grommets with this genuine Impact part restores protection and extends the life of your equipment.

When replacing grommets, consider inspecting these associated components.
Inspect for abrasion damage at entry points where grommets may be missing or worn.
Check panel openings for sharp edges or burrs that could damage new grommets.
Inspect hoses for chafing or wear where they pass through panels.
