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.

Aluminum Flashing Tape
Use this tape outdoors when a water tight bond is required.
Tape with asphalt-based adhesive bonds with almost any building material, including metal, wood, plastic, concrete, brick, asphalt, and glass. Use it for sealing and repair jobs, such as patching gutters. It can be painted.
Tape with rubber adhesive creates a permanent seal against water and humidity and it can endure long-tem UV exposure. Use it to repair holes and leaks on gutters, downspouts, and roofing membranes.

Low-Outgassing Sealing Tape
Tested to meet ASTM E595, a standard used by NASA, this tape seals gaps while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum. The Tedlar backing resists chemicals and wear. And thanks to its acrylic adhesive, this tape will stay put—even when exposed to pulling forces and solvents.

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.
Metalized Duct Tape
It has the look of foil, but this polyethylene-coated cloth tape is more conformable so it won't twist or curl.

Expansion Plugs for Conduit
Seal conduit openings to keep water, dirt, and animals from damaging your wiring. When you twist the nut on top of these plugs, a rubber seal expands to close off the end of your conduit. Tie a rope or pull line to the loop at either end of these plugs to hold them in place during installation.
