LOCTITE 5188 Anaerobic Flange Sealant 300 ml Cartridge Model 2069177 (2024)

LOCTITE 5188 – Anaerobic Surface Sealant (300 ml Cartridge)

The LOCTITE 5188 (Model 2069177) is a high-performance anaerobic flange sealant, designed for reliable sealing of rigid metal flange connections.

It cures in the absence of air between closely fitting metal surfaces, forming a strong and flexible seal that adapts to surface irregularities.

Key features and advantages

• Anaerobic curing technology

Hardens only when confined between metal surfaces.

• Highly elastic seal

Provides durable sealing even under vibration and stress.

• Excellent adhesion (especially on aluminum)

Ideal for applications requiring strong bonding.

• Tolerates slight oil contamination

Ensures reliable sealing even on less-than-perfect surfaces.

• Gap filling up to 0.25 mm

Adapts to scratches and surface roughness.

• Gel-like consistency

Perfect for vertical and overhead applications (non-drip).

• Immediate low-pressure sealing

Provides fast initial sealing performance.

• NSF P1 registered (No. 123758)

Suitable for use in regulated industrial environments.
