Loctite Anaerobic Sealant 50 ml

This anaerobic gasket sealant cures in the absence of air between metal flanges, forming a flexible, solvent-resistant seal. It is intended for mechanics and maintenance engineers who need a reliable liquid gasket on rigid assemblies. The 50 ml bottle covers typical service jobs without excess waste.

Application and common issues

Clean both surfaces thoroughly and apply a continuous bead to one flange before assembly; the product begins to set once confined. Common problems include incomplete cure on large gaps or non-metal substrates, and leakage if the joint is pressurised before full strength develops.

Sustained service behaviour

After full cure the seal resists engine oils, coolants and vibration over long service intervals. It maintains sealing integrity through repeated thermal cycles without hardening or shrinking. The formulation carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm.

Questions about this item

How can I confirm the anaerobic gasket sealant has cured properly after application?

The red anaerobic sealant cures in the absence of air between metal flanges; a solid, gap-free red film between the joint faces shows it has set as intended.

What does the 50 ml tube include and what extra items are needed for use?

The package contains a single 50 ml tube of Loctite red anaerobic gasket sealant; a clean metal surface and a scraper or brush for old residue are required separately.

When should I choose the 50 ml red anaerobic version over other Loctite sealants?

Select this 50 ml red anaerobic grade for rigid metal flange sealing where high temperature resistance and instant low-pressure sealing are specified.
