NuFlex® 333 Aquarium Silicone Sealant is a 100% silicone, one-part, moisture-curing sealant specially formulated for use in the construction of aquariums.

NuFlex 333 is used to create aquariums in almost any shape where the view of the fish is unobstructed. Experts recommend the use of 6.4 mm (1/4”) plate glass for most tanks up to 120 L (30 US gal.) because of their “clear vision” properties.
