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

Press this adhesive-backed plastic tape into place for an immediate light-duty seal.

These sealants include a material certificate with traceable lot number, test report, and product shelf life.

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

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

Made from silicone, these sealants are RTV (room-temperature vulcanizing). They combine the mechanical strength of an adhesive with excellent sealing properties and high flexibility.

These sealants are marine grade, so they stand up to water, corrosion from salt spray, mildew, and UV light.

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

These sealants don't degrade in sunlight.

Wrap this tape tightly around pipe and other surfaces to seal cracks and joints without having to shut down your system.
