Fastening and Sealing Tape

Foil HVAC Tape

Seal foil-jacketed insulation as well as air-conditioning and refrigeration systems with this conformable aluminum tape.

Reinforced HVAC Tape

Reinforced with fiberglass, this tape is flexible yet resists tearing. Use it for sealing and patching insulation and duct.

UL-Printed HVAC Tape

For easy identification, this tape is printed with flexible duct standard UL 181A-P or UL 181B-FX.

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.

Aluminum Flashing Tape

Use this tape for a watertight bond on gutters, roofing membranes, and other building materials.

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.

Super-Thin Splicing Tape

Only 0.0019" thick, so spliced film and paper easily pass through machinery without breaking.

Electrical and Electronic Tape

Conductive Copper Foil Electrical Tape

Use this tape to modify printed circuit boards, shield components, and prototype wiring-board layout and design.

Conductive Aluminum Foil Electrical Tape

The adhesive on this conformable aluminum foil tape is electrically conductive for use on surfaces that can't be soldered. Use it to shield cables and electronic components from EMI (electromagnetic interference).

Conductive Mesh Electrical Tape

This polyester tape has a woven mesh edge that conducts electricity. Use it to shield cables and electronic components from EMI (electromagnetic interference).

Heat-Transfer Mounting Tape

Use this tape to attach components to heat sinks and metal chassis walls in place of screws and other mechanical fasteners. It conducts heat away from sensitive electronics.

Masking and Protecting Tape

Stainless Steel Foil Tape

Made from stainless steel, this noncorrosive, nonstaining, and nonmagnetic tape bonds to metal. Patch scratched coatings and finishes to prevent corrosion in marine, food-processing, and nuclear applications.

Lead Foil Tape

Protect parts from radiation, X-rays, moisture, dust, and chemicals during electroplating and similar processes.

Masking Tape for Thermal Spraying

Aluminum foil is laminated to a tough fiberglass cloth to form a high-strength, reflective tape that resists temperatures up to 500° F. Use it for flame-spray masking and wire harness heat shielding.

Masking Tape Shapes for Stripping and Plating

Cover small spots and holes while paint stripping and electroplating, or use as a moisture and dust barrier. These aluminum foil discs are flexible and conform to irregular shapes.

Weather-Resistant Masking Tape

For outdoor painting jobs, this plastic tape stands up to the elements. The high-tack adhesive works on rough exterior surfaces, such as stucco and masonry.

Heat-Shielding Tape

This tape reflects intense heat to protect sensitive components.

Noise-Damping Foil Tape

Control the unwanted noise that comes from vibrating panels and support structures. This aluminum foil tape reduces vibration by converting it into a small amount of heat.

Adhesive-Back Shim Stock

A durable acrylic adhesive keeps this shim stock from sliding out of place. Cut it into custom shapes to fit your application.

Shim Tape

Level dies, plates, presses, and other machine tools—this shim tape conforms to curves and uneven surfaces.

Fiberglass Weld-Backing Tape

Stick this flexible tape to the back of welding seams to contain spatter and prevent oxygen, water vapor, and other gases from weakening the weld.
