Panel Plug

Panel Plugs are push-fit plastic fasteners designed for closing and finishing circular holes in Air Handling Unit (AHU) sheet-metal panels. They provide a clean, professional appearance while helping reduce air leakage, dust ingress, and vibration-related noise. Installed without tools, panel plugs are ideal for fast assembly and easy maintenance access in HVAC equipment.

Manufactured from high-quality engineering plastics, Panel Plugs are corrosion-free, lightweight, and suitable for continuous use in HVAC environments. The mushroom-head design securely covers panel holes and protects wiring, tubing, and insulation from sharp metal edges, making them a cost-effective and reliable AHU accessory.
