Mix these two-part epoxy surface fillers to create a strong repair in wet environments or underwater.

Also known as sloshing compounds, these surface fillers bond to rough, rusty surfaces in fuel tanks to repair leaks and prevent further corrosion.

Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

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.

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

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

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.

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.

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

This tape has a higher density than standard tape for a better seal between threads.

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

Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. They work especially well on metals.

To allow time to adjust and position parts, these epoxies remain workable for at least 90 minutes.

Urethane adhesives are the most flexible, so they bond dissimilar materials and damp vibration.

To keep these adhesives from squeezing out during clamping and give a consistent bond thickness, they're mixed with small glass beads.
