LOCTITE 1448091 5776 Thread Sealant - Medium Strength General Purpose 50ml - Yellow
LOCTITE 5776 is a general purpose sealant for locking and sealing of all coarse metal threads. It ...LOCTITE 5776 is a general purpose sealant for locking and sealing of all coarse metal threads. It is suitable for fast application at low temperatures and is therefore suitable for outdoor maintenance applications. LOCTITE 5776 is qualified for gas and water pipes and is also certified for potable water applications up to 60 deg C. This product hardens between engaged metal surfaces and prevents independent loosening and leaks caused by shocks and vibration. Through its thixotropic behavior, LOCTITE 5776 reduces liquid product after application on the component.
The LOCTITE 1448091 5776 is a medium-strength, general-purpose thread sealant designed for locking and sealing coarse metal threads. It's ideal for outdoor maintenance applications due to its performance at low temperatures. While it effectively prevents leaks and independent loosening from vibration, users should be aware of its medium strength, which may not be suitable for extremely high-stress applications. This sealant offers good thixotropic behavior, reducing drips after application.

Extended Product Information
FAQs
What is the temperature range for LOCTITE 5776?
LOCTITE 5776 is suitable for application at low temperatures and is qualified for potable water applications up to 60°C.
Is this sealant suitable for fine threads?
No, LOCTITE 5776 is specifically designed for locking and sealing of all coarse metal threads.
How long does it take to cure?
Fixture time on steel is typically 10-20 minutes, and full cure is usually achieved in 24 hours at room temperature (22°C).
Can I use this on plastic pipes?
This product is designed for metal threads. Compatibility with plastics should be verified, but it is generally not recommended for use on plastic components.
What does 'thixotropic behavior' mean for me?
It means the sealant has low viscosity when agitated (like during application) but becomes more viscous when at rest, reducing sagging and dripping after application, leading to a cleaner process.
Is it safe for drinking water systems?
Yes, LOCTITE 5776 is certified for potable water applications up to 60°C.
What is the strength of this thread sealant?
It provides a medium strength general-purpose lock, which prevents independent loosening from shocks and vibration.
Troubleshooting
Sealant not hardening
Ensure surfaces are clean and free from contaminants. Check that the assembly is not being subjected to excessive movement before cure. Verify operating temperature is within the product's recommended range.
Excessive dripping during application
While thixotropic, very large gaps or inverted applications might still see some flow. Ensure threads are clean and properly engaged. Allow a moment for the product to 'wet' the threads before full tightening.
Difficulty disassembling
LOCTITE 5776 provides a medium strength lock. For disassembly, apply localized heat (e.g., using a torch) to around 200°C, then use hand tools to remove the fitting.
Sealant looks dry or pasty
This can occur if the container has been open for an extended period or exposed to air. Check the expiration date. If within date, try stirring thoroughly, though product performance may be compromised.
Pros and Cons
Pros
Effective at preventing leaks and vibration-induced loosening.
Suitable for low-temperature applications and outdoor use.
Certified for potable water and qualified for gas pipes.
Reduces waste and mess due to its thixotropic properties.
Cons
Medium strength may not be sufficient for very high-stress or high-vibration environments.
Designed for coarse metal threads, not fine or specialized threads.
Requires time to cure fully for maximum strength.
Yellow color might be undesirable in some aesthetic applications.
Setup, Compatibility & Care
Setup:
Ensure all threads are clean and free from grease, oil, and contaminants.
Apply the sealant evenly to the male threads, avoiding the first 1-2 threads to prevent excess squeeze-out into the fluid path.
Assemble the parts and tighten to the recommended torque.
Allow the sealant to cure. Full strength is typically achieved after 24 hours at room temperature.
Compatibility:
Suitable for all coarse metal threads (e.g., NPT, BSP).
Recommended for use on metals like steel, aluminum, and brass.
Certified for potable water applications up to 60°C and for gas pipes.
Care:
Store in a cool, dry place away from direct sunlight.
Keep the container tightly sealed when not in use.
Avoid exposure to extreme temperatures during storage.
Clean up any excess uncured sealant with a damp cloth. Cured sealant may require mechanical removal.
