Flexible Dust Plug

Specialty Products

  • Flexible-based material for a firm and permanent fit over uneven surfaces for proper mounting.
  • Extremely dense, close fiber configuration for a non-oriented design, allowing the dust plug to be applied in any direction and reducing labor.
  • Aggressive premium adhesive solution to ensure durable and long-lasting lifespan.
  • Available in cut-length as well as linear pieces.

Sealing Advantages

  • Reduces or eliminates air infiltration, sound/vibration, and operational force
  • Fits uneven surfaces (e.g., welded corners, pockets)
  • Fits securely and eliminates “rise” due to flexible base and premium adhesive
  • Industry-leading durability and longevity with ultrasonically welded polypropylene filament assembly
  • 360º wrap sealing function around perimeter, corners, radius, and other difficult to seal areas

Sealing Application Benefits

Flexible Backing Fits Toughest Applications

Flex Plug’s 360º wrap functionality allows it to be internally or externally wrapped on almost any application. The Flex Plug is ideal for welded corners, pockets, angles, slants and other contours, and it can conform to irregular surfaces.

Improved Performance by Average of Up to 250%

These lightweight, high-density dust barriers performed an average of 100-250% better than standard dust plugs in isolated tests against air infiltration. They also provide superior performance in sound and vibration-dampening, light-filtering, and reduced friction.

Increased Lifespan with Premium Adhesive

Flex Plugs come with our durable premium PSA adhesive solution that has pull forces 300% better than standard dust plug adhesives, increasing seal lifespan in an application.

Reduces Time of Labor by Approx. 60%

Premium Flex Plugs’ non-oriented design allows them to maintain superior performance regardless of the direction they are placed, reducing the labor time it takes to orient plugs in an application. The premium Flex Plug also comes with an innovative pull tab quick-release liner that promotes quicker installation, saving 60% of labor time.
