Hardcast 309781 Foil-grip 1403-181BFX Silver Foil Rolled Duct Sealant Tape 2 Inches X 100 Feet

Product Description

The Hardcast 309781 Foil-Grip 1403-181BFX is a UL 181BFX listed, pressure-sensitive foil tape designed for duct joint sealing and general-purpose duct sealing applications. It is built for HVAC professionals who need a reliable, long-lasting seal on a wide range of duct materials. This silver foil tape is suitable for both indoor and outdoor use and delivers an instant, water-resistant bond to sheet metal, duct board, flex duct, PVC coated duct, and duct wrap vapor barriers. It is also approved for subgrade application on PVC coated duct, making it one of the more versatile options in the duct sealing category. The modified butyl sealant backing provides a strong adhesive grip rated at greater than 10 pounds per inch of adhesion strength. At 17 mil thickness, this tape is built to handle the physical demands of commercial and residential HVAC installations without tearing or lifting. The roll measures 2 inches wide by 100 feet long, giving HVAC technicians ample tape for multiple duct connections on a single job. The performance temperature range runs from -20 degrees Fahrenheit to 180 degrees Fahrenheit, making it suitable for attic installations, crawl spaces, and exterior mechanical equipment. The tape carries a 40-year cycle rating, supporting its use in long-term duct system assemblies. It is LEED compliant and meets SCAQMD Rule 1168 standards for low VOC emissions, which is important for green building projects and air quality compliance. With a 2-year shelf life, this tape stores well in service vehicles and supply rooms. The tensile strength of 20 pli and 1400 psi average ensures the tape holds even under pressure differentials common in forced-air duct systems. UV resistant construction adds durability in exposed outdoor applications.
