About Sealant Flexibility
More
Metal Duct HVAC Sealants
Seal metal-to-metal joints in ductwork. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.
HVAC Sealants
Form flexible water-resistant seals on metal, plastic, and rubber joints in heating, ventilation, air conditioning, and refrigeration applications. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain.

Heavy Duty Sealing Tape
This tough, abrasion-resistant tape sticks to itself, so you can layer it over joints and seams to create an extra-strong bond. The thick adhesive conforms to keep water out, even in extreme conditions. A liner helps tape keep its shape as it's applied. Remove the liner to mold tape to fasteners and gaps.

Metal-Detectable Tape
A layer of foil inside this tape will set off metal detectors if it falls into your food processing line, alerting you to the contamination. Write on the paper surface to label items around your facility—it’s brightly colored to help you identify tools, packaging, or other equipment. Tough enough for repairs, this tape has strong adhesive that will stick to smooth or rough surfaces. It also helps you comply with Hazard Analysis and Critical Control Point (HACCP) programs.
This tape has FDA-compliant adhesive, so it is safe for use with food in packaging, transportation, or storage applications.
