Loctite 569 pipe thread sealant
Loctite 569 is an anaerobic pipe thread sealant supplied in a 1.7 fl oz brown bottle. It cures in the absence of air to seal metal threaded connections in hydraulic systems. The product withstands liquid pressures up to 10,000 psi and operates between -65 and 300 degrees F. Application is by brush and clean-up uses Loctite solvent.
For metal hydraulic threads only
This sealant suits maintenance and assembly tasks on metal pipe threads carrying hydraulic fluid. It is not for plastic piping, gaseous oxygen systems or potable water lines. Buyers needing a sealant for non-metallic materials or different media should look at alternative chemistries. The anaerobic cure mechanism requires active metal surfaces to polymerise.
Fits standard maintenance workflows
The 50 mL bottle fits tool caddies and allows brush-on application without special dispensing equipment. It frees the assembler from PTFE tape winding and provides a liquid seal that resists vibration loosening. The cured joint meets OSHA Hazard Communication Standard 29 CFR 1910.1200 requirements. No primer is mentioned in the data.

Questions about this item
Does the 569 series sealant need a specific thread material to cure properly?
It is formulated for metal threads and cures anaerobically when confined between metal surfaces.
Will the brown 569 sealant handle the -65 °F to 300 °F range of my existing hydraulic fittings?
Yes, its rated operating window spans -65 °F minimum to 300 °F maximum.
How can I confirm the 1.7 fl oz bottle has cured to the full 10,000 psi liquid rating after assembly?
Allow the anaerobic cure to complete on metal threads, then pressure-test the hydraulic system to its working pressure.
