SprayTech part 0277389 is a foam tape used to create a protective seal between the sprayer's cover or access panel and the main housing. This compressible foam tape helps prevent dust, debris, and moisture from entering critical internal components while also reducing vibration and noise. Replacing worn or deteriorated foam tape restores proper sealing and environmental protection on compatible SprayTech units.

The SprayTech 0277389 Foam Tape is a compressible sealing strip designed to fit between the access covers, doors, or panels and the main housing of compatible CS series sprayers. It creates a protective barrier that helps keep dust, dirt, moisture, and chemical overspray away from sensitive internal components such as the motor, control board, and electrical connections.
Over time, foam tape can compress, dry out, crack, or peel away, compromising the seal and allowing contaminants to enter. Replacing the foam tape restores the original sealing integrity, helping to extend the life of internal components and maintain reliable operation in harsh job site conditions.
| Environmental seal | Prevents dust, dirt, and moisture from entering the housing |

| Vibration dampening | Reduces rattling and noise between panels and frame |
| Thermal insulation | Helps maintain consistent internal temperatures |
| Chemical barrier | Resists overspray and minor chemical exposure |
| Compressed / flattened | No longer provides a tight seal when panel is closed |
|---|---|
| Cracked or brittle | Dry rot or age-related deterioration |
| Peeling adhesive | Tape lifting away from mounting surface |

Check for cracks or warping that may prevent proper sealing.
Ensure latches hold the panel snugly against the foam tape.
If contamination is visible, inspect and clean internal electronics.
