LOCTITE 515 FLANGE SEALANT 50ML

Ensure a perfect, leak-free seal every time with Loctite® 515, a medium-strength, anaerobic flange sealant designed for use on machined, rigid metal flanges. This methacrylate-based industrial gasketing compound creates a strong, flexible seal that resists vibration, pressure, and thermal cycling — eliminating the need for traditional pre-cut gaskets.

Loctite 515 fills gaps up to 0.25 mm, curing between closely fitted metal surfaces to form a tough, chemical-resistant seal. With a medium cure speed and 6 N/mm² tensile shear strength, it’s ideal for pumps, compressors, thermostats, transmission housings, and axle covers, providing long-term reliability in demanding mechanical and automotive applications.

The purple formulation allows for easy identification during application, while its temperature range of –55°C to +150°C ensures dependable sealing across a wide range of environments.
