LOCTITE 515 Gasket Maker & Flange Sealant is a flexible gasketing material for use on rigid machined flanges with less than 0.015″ (0.381 mm) gap. OEM approved – use where OES specify 515 or “anaerobic” gasket (cures in absence of air). Eliminates preformed, pre-cut, paper, rubber, and cork gaskets. Flexes with flanges that move in service.Gasketing product for machined metal flanges. Medium strength. 30 min fixture time. Can also fill gaps up to 0.25 mm.LOCTITE 515 is a medium strength (6 N/mm tensile shear strength), medium cure speed, methacrylate-based industrial gasketing product designed for machined, rigid metal flanges. The product, which cures anaerobically, is suitable for gaps up to 0.25 mm. It is used typically as a form-in-place product for pumps, thermostats, compressors, transmission housings and axle covers. Ideal for machined metal components.LOCTITE automotive aftermarket products are not just OEM-specified, they are also designed by auto manufacturers and lab tested.
