These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Formulated to flow into small spaces, use these sealants between fine threads.

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Formulated for high lubricity, these sealants allow easy assembly of finely threaded hydraulic and compressed air system components. They're also free of fillers that could contaminate system media.

This tape contains nickel to prevent seizing and galling associated with stainless steel threaded connections. It’s also good for use with other metals.

Use color to identify water, gas, and chemical connections.

Fix roof leaks in cold and wet conditions. These sealants can even be applied underwater.

Clean surfaces before applying sealant to promote bonding.

Designed for use on ovens and kilns, these sealants form a durable, rock-hard seal after firing.

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.

These non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Thinner than non-sag sealants, these flow easily into cracks and have a smooth finish.

Form flexible water-resistant seals on metal, plastic, and rubber joints in heating, ventilation, air conditioning, and refrigeration applications.

Repair equipment and vehicle windows with these sealants that are rated to withstand impact within three hours of application.

These sealants don't degrade in sunlight.

Press this pliable rope into place to hold glass in window frames and seal leaks.

Patch and seal roofs, window frames, gutters, and vents with this conformable tape.

Stop water penetration with this tacky, flexible tape. It conforms to irregular shapes and expands to fill gaps. Use it on freezers, windows, and in marine applications.

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 fasteners and gaps to keep water out, even in extreme conditions.

Create strong, permanent bonds that can replace mechanical fasteners.

The acrylic adhesive on this tape sticks to hard-to-bond materials, such as plastics and powder-coated surfaces.

Use these clear sheets for strong, invisible bonds.

These foam discs and squares have extra-strong adhesive on both sides to create permanent bonds.

Remove mounted objects from most surfaces without leaving residue behind.

Tape is cut into convenient discs and rectangles.

Tape is cut into convenient discs and rectangles.

The most conformable foam tape we offer, use this tape for mounting, gasketing, and damping sound and vibration. It has adhesive on both sides.

When exposed to moisture, this resin-coated fiberglass tape becomes rock-hard in about 30 minutes. Use it for rigid, waterproof repairs.

Make invisible repairs with this clear tape. The weatherproof adhesive won't turn yellow outdoors.

For quick repairs, these small rolls of tape don't have a spool so they easily fit into a pocket.

Also known as gaffer's tape, this conformable cloth tape leaves no residue when removed. The matte finish won't reflect light. Choose a color that will blend in for temporary repairs.

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

This tape has a high-tack adhesive that bonds quickly to rough surfaces such as wood, plaster, stucco, brick, metal, and cement.

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

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