Premium Butyl Gasket 3/16" 25-ft

Item CodeDDBTL500SKU21042

Butyl gasket is used in tape and bead form to seal transverse duct connections systems helping to provide a moisture and air tight seal. This tighter seal also helps reduce energy waste and noise. Wherever flanges are used in connecting parts of a duct system, the potential for air leakage exists. Besides contributing to energy waste, leaks can also create noise. Sealing of ductwork can be accomplished with the use of a pliable material which adheres to flanged surfaces. When this material is attached to a flange which is then assembled to a second flange, the material is compressed and fills gaps and irregularities creating a flexible seal. Duro Dyne BTL500 is a UL Classified permanently soft caulking compound designed for sealing flanged joints in duct systems. It adheres to clean dry metal surfaces and does not promote corrosion.

  • Duro Dyne Butyl gasket can withstand movement without cracking
  • Adheres to most dry, clean surfaces such as steel, aluminum, plastics, wood and concrete
  • Excellent resistance to water, alcohols, mild acids and mild bases
  • Non-corrosive
  • All Duro Dyne Butyl gasketing is considered a non-irritant for "appraisal of the safety of chemicals in food, drugs and cosmetics"
