Loctite® Gasket Sealants / Flange Sealants

Loctite® Gasket Sealants and Flange Sealants are single component anaerobic adhesives that completely fill gaps, creating an impervious barrier that prevents fluid and/or gas leaks without the use of hard gaskets. Loctite gasket and flange sealants provide a low cost, high quality alternative to molded rubber, paper, metal and other hard gaskets. Other anaerobic products offered by Henkel include retaining compounds, thread sealants and threadlockers.

Economical and Versatile Gasket Sealing
Loctite® gasket sealants / flange sealants can provide up to 95% material savings over hard gaskets while offering flexibility in design, allowing for lower cost manufacturing methods. This gasket sealing method also provides resistance to low pressures immediately after flange assembly.
