Reliable flange sealing with Loctite 128068

Practical benefits

Semi-flexible durable seal: The semi-flexible compound adapts smoothly to minor flange movements, ensuring your rigid metal joints remain leak-free.
Extended time for alignment: Slow anaerobic curing gives you ample time to position parts accurately without premature shimming between flanges.
Immediate low-pressure resistance: You achieve instant sealing against low pressures right after assembly, safeguarding transmission housings and covers.

In a nutshell

The right choise for

With Loctite 128068 1K flange sealant, you create reliable and durable seals between rigid metal faces and flanges. This gel-like liquid gasket cures anaerobically at room temperature when confined without air between close-fitting metal surfaces. Because it cures very slowly, you have ample time to align components such as transmission housings and axle covers precisely without premature clamping. The cured semi-flexible seal easily accommodates minor joint movements and vibrations, effectively preventing oil and fluid leaks. Additionally, you benefit from immediate resistance to low pressure right after assembling the flanges. Supplied in a convenient 300 ml cartridge, this sealant enables clean and controlled application on every job.
