Shurtape SHUR-111163 Sf 686 Foil Mastic Tape 3in X 100ft

Product Description

The SHURTAPE SHUR-111163 is the SF 686 ShurMASTIC silver printed foil mastic tape, a heavy-duty sealing tape designed for air-tight and moisture-free connections in HVAC duct systems. Measuring 3 inches wide on a 100-foot roll, it delivers a conformable, durable seal on a wide range of duct substrates. HVAC technicians and sheet metal workers use this tape for both indoor and outdoor installations where a reliable vapor and air barrier is required. The foil-backed mastic construction bonds firmly to irregular surfaces, making it well suited for field sealing during new construction and retrofit work.

This tape is rated for use on Class 1 Flex Duct, sheet metal duct, PVC coated duct, and duct wrap vapor barriers. It is approved for subgrade application on PVC coated duct, expanding its use to below-grade mechanical installations where moisture exposure and soil contact are concerns. The indoor and outdoor rating makes it a versatile choice for commercial and residential HVAC projects where a single tape product needs to perform across varied conditions and substrates.

Installation Notes

This tape is typically installed by licensed HVAC technicians or sheet metal workers during duct fabrication, connection, or sealing work. Surfaces should be clean, dry, and free of dust or grease before application to ensure full mastic adhesion. When working on pressurized or active duct systems, shut down the air handler before accessing duct connections. Always verify that tape products used in duct systems meet local mechanical code requirements, including applicable SMACNA and UL standards referenced in the installation specifications.
