Gaskets are used to prevent leakage of fluids or gases by forming impervious barriers. For successful gasketing, it is necessary for the seal to remain intact, and leak-free over a long period of time. The gasket must be resistant to fluids and/or gases, and withstand the operating temperatures and pressures to which it is subjected.

Apply LOCTITE® SF 7200 on old gasketing adhesive and use a wood or plastic scraper to remove residues. Remove burrs. For thicker layers, several applications may be necessary. Ensure compliance with application instructions on the technical data sheet.



LOCTITE® SF 7063 recommended to degrease and clean surfaces prior to applying adhesive.


Adhesive application

Apply a continuous bead of e.g. LOCTITE® 510 onto one flange surface. Place the bead close to  the inner rim of the flange and encircle all holes. Alternatively, it can be applied by a roller onto larger flanges.



Assemble flanges and tighten bolts as soon as possible.

If disassembly is needed, remove the bolts with standard hand tools. Use jacking-screws or cast-on bosses and recesses to life flanges apart. For corroded or seized parts, use LOCTITE® 8040 Freeze & Release to loosen the bolts.
