A. Yes, Loctite® Gasket Eliminator Flange Sealants can be used, but the gap space between the mated parts or thickness of the O-ring would have to be taken into consideration, since the gasketing adhesives have limits in gap-filling capability. Please refer to our Technical Data Sheet for details.
A. Yes, Loctite® 510 Gasket Eliminator Flange Sealant can resist up to 204°C (400°F).
A. As cast iron is rigid structure, with not much thermal shrinkage and expansion, we recommend Loctite® 509.
A. As aluminum has a big CTE, you need a product that can flex with the part and maintain a good seal. Therefore Loctite® 518 Gasket Eliminator Flange Sealant and Loctite® 5118 Gasket Eliminator Flange Sealant would be the best.
A. It is very simple. You can use various application methods, such as direct from tube, screen printing, a caulking gun, or an automatic robot system.
A. It’s not necessary: The existing surface roughness for the cut gasket is enough. You can simply apply and assemble without additional processing.
A. No, as it doesn't cure outside, it will disperse into the internal fluid, causing no harm to the internal system.
A. These are both anaerobic flange sealants designed for rigid machined flanges. They are similar products, one of the key differences being that Loctite® 518 is better for use on aluminum flanges. Thus, Loctite® 518 probably can replace Loctite® 515 for most applications. However, Loctite® 518 is generally a faster-setting anaerobic adhesive and it may tend to cure too quickly on very active metals like brass. In this instance, Loctite® 515 may be a better choice.
A. Loctite® silicone gasketing products are best suited for large-gap gasketing applications and stamped-metal assemblies where flange flexing occurs.
