Ultrafab industrial brush seals (or skirting seals) are designed to meet the demands of the most damaging high traffic industrial or commercial applications – whether they use extruded sealing or brush based elements. Our two popular industrial brushes include the Ultrafab® Q Series and Ultrafab® QD Series. These seals and sweeps provide you with the options you need to build a more efficient product at a reduced cycle time.


Quick Features

  • Skirting seals and overhead/industrial door skirting seals are designed for the most demanding industrial and commercial applications
  • Optional welded-on plastic tab eliminates the need for the aluminum mount
  • Square backed skirtings are ready to use with aluminum mounting

Ultrafab® Q Series

industrial brush seals

Square or diamond based strip brush

A totally robust seal that uses compacted fibers and Ultrafab’s unique pile directors to build an extremely durable, cost effective product. Our unique ultrasonic welding assembles the fin, fibers, and backing into an integrated, unified assembly that won’t break apart during fabrication or while in use.

Q Benefits

  • Guaranteed uniform pile height and backing widths due to unique non-woven manufacturing system
  • Compatible with mounting applications when welded to a polypropylene backing strip
  • Assures a tighter seal and barrier against air and water infiltration when pile seals use round yarns for optional structural integrity and consistency
  • Reduced dirt, water, and air infiltration with brush seals
  • Eliminate the need for metal backed products with diamond base skirt weatherseals configured to your specifications

Q Specs

  • Materials: standard polypropylene (fins optional), nylon backing or filaments with monofilaments or yarn options
  • Colors: black, white, gray, brown, beige
