HVAC Sealants
Form flexible water-resistant seals on metal, plastic, and rubber joints in heating, ventilation, air conditioning, and refrigeration applications. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, 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.

Waterproof Epoxy Structural Adhesives
Even when used under water, these adhesives maintain their strength. The most weather- and chemical-resistant structural adhesives, epoxies tend to work especially well on metals.
The size listed is the combined total of the two parts. For putty adhesives, slice off the required amount, then knead it together to form a moldable adhesive.
WaterWeld and 11801, as well as one-time-use packets, can be applied to wet surfaces or under water.
