About this item

• RELIABLE ADHESION. Works on all metals, including passive substrates (e.g. stainless steel, aluminum, plated surfaces) & tolerates minor contamination by oils (e.g. motor oils, corrosion protection oils, cutting fluids).
• FLEXES WITH MOVEMENT. Adds flexibility to rigid machined flanges that move in service & eliminates the need for preformed, paper, rubber & cork gaskets.
• EASILY REMOVABLE. Well suited for automotive and other applications such as water pumps, thermostat housings, transmission pans, transmission case covers, transaxle casings, O-ring replacement.
• CONVENIENT CURING. With primer, sets in 15m – 2hrs. Without primer, sets in 1-12hrs.
• LOCTITE 515 is designed for close fitting flanged parts with gaps up to 0.25 mm (0.01 in).
