Also known as sloshing compounds, these two-part epoxies bond to rough and rusty surfaces in fuel tanks to repair leaks and prevent further corrosion. They withstand permanent immersion in fuel, oil, and harsh solvents. Use them with metal, plastic, and fiberglass tanks. Mix the smaller can with the bigger one and pour into your fuel tank. Rotate the tank to coat the interior and dump out any excess. Allow to cure overnight. Size listed is the combined total of the two parts.

Repair small leaks and cracks in coolant systems for commercial vehicles and industrial equipment. These surface fillers meet ASTM D3147 for their ability to stop leaks in engine cooling systems. Pour them into your coolant to fix both internal and external leaks. They contain ceramic microfibers and copper particles to create a permanent seal. They’re compatible with antifreeze and other coolant system additives.

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility. They’re non-sagging, so they won't drip from vertical and overhead surfaces.

Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Seal concrete joints in high-traffic areas—these sealants stand up to heavy wear and tear, such as steel wheel traffic. They're non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone rubber, 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. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation. For high-wear applications, choose a harder sealant for the most abrasion resistance.

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. Formulated without PTFE, these sealants are less slippery and less likely to result in overtightenting than sealants that have PTFE, making them good for plastic pipe where overtightening could lead to cracks and breaks. They have low locking strength, so they can be adjusted without tools.

Take your time to precisely align parts before bonding, and maintain flexibility afterward. These adhesives won't harden until you expose them to a compatible light source. They also remain elastic so the bond can bend without breaking.

For easy positioning, these adhesives remain tacky for hours. Once items are in place, apply pressure to create a permanent bond. The blue color shows where adhesive has been applied.

Bonds to itself for a permanent, watertight seal. This tape has no adhesive, so it won't dry out and crack, which can cause standard tape to fail over time. The rubber backing molds to irregular surfaces and withstands demanding conditions, making this tape a good choice for patching and sealing anything from roofs to pipes.

Acrylics bond with the widest range of materials of any adhesive. They adhere to plastic especially well, requiring little surface preparation.

These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

These spray contact adhesives adhere quickly. Spray a thin, uniform coating on one surface, air dry, and then bring together to bond.

Mixed with rubber for resilient bonds that withstand sudden stress, shock, and vibration better than standard acrylics. Acrylics bond with the widest range of materials of any adhesive. They adhere to plastic especially well, requiring little surface preparation.

These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

Spray a thin, uniform coat of adhesive on one or both surfaces, air dry, and then bring together to form strong bonds.

Apply these adhesives on two surfaces, air dry, and then bring together to bond.

With excellent resistance to corrosive chemicals, these epoxies maintain bonds in tough conditions.

Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an adhesive that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.

Join plastics that standard instant-bond adhesives can't grip. These adhesives stick to smooth materials, such as polyethylene and polypropylene. Clean and prepare the surface with primer so the adhesive can spread, dry, and gain strength.

Add an accelerator after the primer and before the adhesive to reach a full-strength bond faster.

Impervious to the swelling effects of oils, fuels, and solvents, use this high-strength silicone rubber sealant to assemble and repair fuel systems and tanks. Silicone rubber forms a tough, rubbery, UV-resistant seal that remains flexible over time. It's non-sagging, so it won't drip from vertical and overhead surfaces. Also known as RTV (room-temperature vulcanizing).

Elongation and joint expansion/compression tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. This sealant is best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.

Form bonds with twice the strength of our other spray contact adhesives. Spray a thin, uniform coat of adhesive on one or both surfaces, air dry, and then bring together to adhere.

Join polyethylene, polypropylene, and other plastics standard acrylics can't join.
