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.

Apply these sealants in cold temperatures, on wet surfaces, and even through running water.

A combination of hardness and surface tension makes these sealants resistant to punctures, cuts, and abrasion.

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

Resistant to mold and mildew, these sealants are well suited to high-humidity environments.

Also known as neutral-cure sealants, these won't discolor copper, brass, and concrete.

Mix a small amount of water-based paint with this caulk to match the color of your surface.

Also known as Torr Seal, this sealant forms a rigid bond that seals leaks on vacuum systems or components.

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

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.

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

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