High Demand Item – Frequently Reordered by Contractors
Solution 40 is a single-component, room-temperature-cure anaerobic flange gasketing sealant. Applied as a bead to one flange face, it cures between the mating metal flanges and fills surface voids to create a thin, resilient, vibration-proof seal that will not leak even if a flange is chipped or damaged.
It cures without shrinkage, remains flexible to flex with the flanges, and resists oils and solvents through severe thermal and pressure cycling. Supplied in a 50 ml tube and a 300 ml cartridge.
