Loctite 518 Gasket Maker Flange Sealant 2096059, 50 mL Tube
- The Loctite 518 Gasket Maker (part number 2096059) is a primerless, anaerobic flange sealant designed for forming flexible, reliable gaskets on aluminum, iron, and steel mating surfaces when conventional gaskets are unavailable.
- Features:
- Anaerobic curing formulation — cures in the absence of air between close-fitting metal surfaces for strong, durable seals
- Primerless application — tolerates minor surface contaminants and eliminates the need for primer prep
- Semi-flexible, solvent-resistant seal — adapts to surface irregularities and resists tearing or decay over time
- Gap-filling capability up to 0.25 mm — bridges uneven surfaces for effective sealing
- Easy disassembly — parts separate cleanly, and old sealant can be removed with a putty knife after extended service
