DataCenter BlackBrush 03SEALEZE® is a leading provider of brush solutions for computer server rack OEMs, telecom and call center operators and contractors, point-of-purchase and merchandising display manufacturers, and a host of technical furniture producers for audio-visual, computer, and electronic equipment.

Our line of brush products provides flexible solutions from surface mount grommets to under-floor-through-wall cable seals. Combining our experience in applying strip brush to a range of sealing applications and our XtraSeal technology, brush seals can substantially reduce data center energy consumption.

Typical uses for SEALEZE® brush seal solutions in these applications include:

  • Sealing conditioned air inside of server racks or under raised floors
  • Managing large and complex cable bundle pass-through
  • Enabling server rack to server rack cabling
  • Providing an aesthetic, conforming gap-closure in retail installations
  • In-fill panels for standard 19” U racks that allow cable pass-through

Energy loss is a common problem for data centers and can come from within the data center as well as outside. Our line of door seals for hot and cold aisle containment provide a more complete seal around double doors, saving energy and keeping out unwanted pests. They can also enhance the appearance of entry way doors with a more finished look.

We offer several different types of grommets, including:
