Product Description
The POLYKEN 1953973 Professional-Grade Mastic Sheet Metal HVAC Foil Tape is designed for sealing duct joints, seams, and connections in HVAC sheet metal applications. This 1.89" x 10 yd roll features a durable aluminum foil backing with mastic adhesive, giving contractors and maintenance teams a tape-format alternative to traditional mastic putty for creating waterproof and air-tight seals. Lowe’s lists the product as Professional-Grade Mastic Sheet Metal Tape with aluminum backing, 17 mil thickness, and interior/exterior use.
The technical product family aligns with Polyken 367-17 FOILMASTIC, which Amcor/Berry lists as a UL 181B-FX Listed Foil Sealant Tape for HVAC with 17.0 mil thickness, foil facestock, rubber/butyl mastic adhesive, and a -20°F to 200°F operating temperature range.
This tape is a strong choice for HVAC service work, duct sealing, retrofit jobs, and repairs where a conformable, professional-grade foil mastic tape is preferred over brush-on mastic. Its puncture-resistant foil backing supports use on joints and seams in Class 1 duct work, while the mastic adhesive helps provide a durable seal for air-leak reduction and moisture control.
