These surface fillers come in a pen for precision application. After applying, use the LED on the back of the pen to instantly cure.

Repair small leaks and cracks in coolant tanks for commercial vehicles and industrial equipment. These surface fillers meet ASTM D3147 for their ability to stop leaks in engine cooling systems.

Repair stripped threads on female connections, such as oil pans, valve covers, and distributor caps.

Clear enough to read through, these UV-resistant sealants allow optimal light transmission for use with solar cells and fiber optics.

Clear enough to read through, this UV-resistant sealant allows optimal light transmission for use with solar cells and fiber optics.

These structural sealants combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

Also known as thumb-grade caulk, this forms a non-hardening, moisture-resistant seal that remains pliable.

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

Impervious to the swelling effects of oil, fuel, and solvents, use these high-strength sealants to assemble and repair fuel systems and tanks.

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 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.

Wind this multifilament cord into the grooves of tapered pipe threads to quickly create a seal.

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

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

These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.

Seal roof openings around pipes, vents, and chimneys.
