LOCTITE® 5188

Features and Benefits

Gasketing Product - excellent oil and chemical resistance. General purpose. Highly flexible.
LOCTITE® 5188 is a highly flexible sealant which cures when confined in the absence of air between close-fitting metal surfaces. It is designed for use on rigid metal flanged connections, particularly where minor oil contamination of the flange surfaces can occur. The product is particularly suitable for use on aluminium substrates where very good adhesion is needed. It ensures an instant, low-pressure seal. For sealing rigid flange faces on transmissions and engine casings.
  • Ideal for sealing all kinds of rigid metal flanges, especially aluminium flanges
  • Excellent chemical resistance, highly flexible
  • Excellent in demanding applications
  • Superior adhesion, can tolerate slight oil contamination on the flange surface
