In industrial machinery, reliable flange sealing is essential to prevent leakage, maintain equipment stability, and ensure long-term operation. LK574 Anaerobic Gasket Sealant is designed precisely for these requirements. As a one-component, medium-strength anaerobic sealant, LK574 offers strong performance and consistent reliability—making it a preferred choice for manufacturers, maintenance service providers, and industrial users seeking both quality and cost efficiency.
1. What Is LK574?
LK574 is a single-component, methacrylate-based anaerobic gasket sealant that cures when trapped between closely fitted metal surfaces in the absence of air. Once cured, it forms a durable, chemical-resistant polymer gasket that effectively seals rigid metal flanges.
Key characteristics
- Medium strength anaerobic sealant
- Thixotropic — prevents product migration after application
- Designed for rigid metal surfaces and close-fitting flanges
- Ideal for gearbox housings, engine castings, pumps, and general machinery
2. Performance Features of LK574
● Reliable sealing performance
LK574 cures into a tough polymer that seals gaps up to 0.5 mm, maintaining excellent sealing integrity even under mechanical stress. It prevents oil, coolant, and other fluid leaks and remains stable across temperature fluctuations from –50°C to +150°C.
● Fast fixture time and full curing
- Fixture time: approx. 15 minutes
- Full cure: approx. 24 hours
This ensures quick assembly and minimal downtime—especially valuable for maintenance tasks and production lines.
● Strong mechanical properties
According to the TDS:
- Compressive shear strength: ≥6.0 MPa
- Lap shear strength (steel): ≥8.5 MPa
- Tensile strength: ≥5 MPa
These values demonstrate LK574’s ability to maintain stable bonding between metal components under demanding mechanical loads.
● Excellent chemical resistance
After long-term exposure (100h–1000h), LK574 retains high strength in the presence of:
- Motor oil
- Lead-free gasoline
- Ethanol
- Acetone
- Acidic and alkaline solutions
- Water–glycol coolant
This makes LK574 suitable for harsh automotive and industrial environments.
3. Cost-Effectiveness: A Major Advantage
One of the strongest reasons users select LK574 is its outstanding cost-performance ratio.
Compared with products from competitors well-known worldwide, for example, Loctite 574, LK574 provides quite similar functional capability at significantly more economical price. This benefit is especially important for:
- OEM manufacturers
- Large-scale maintenance teams
- Industrial users with regular consumption
- Companies looking to optimize procurement budgets
LK574 allows users to maintain high sealing reliability without paying for unnecessary brand premiums.
4. Fast and Stable Delivery
Rapid delivery is made possible not by local distribution centers, but by an efficient internal operation system.
Ningbo Locke’s streamlined management structure, automated production lines, and well-organized logistics coordination enable:
- Shorter production cycles
- Faster order processing
- Stable and predictable lead times (7-14 days for like 1800 pcs of 300ml cartridge pack)
- Rapid response to urgent customer demands
Because the production and decision-making processes are highly efficient, LK574 can be manufactured, packaged, and dispatched quickly—allowing customers to receive their orders without the long delays often associated with complex international supply chains.
P.S.: glue is restricted by shelf life, so to keep a lot in stock to realize fast delivery is not a good idea. To be manufacture fresh is the key to deliver goods to buyers with maximum shelf life left thus to liberate pressure in stock before sale.
5. Comprehensive After-Sales and Technical Support
LK574 is supported by a complete technical and customer service system, including:
● Application guidance
- Recommended surface preparation
- Optimal bead size and dispensing method
- Curing performance optimization
- Pressure-testing guidance after assembly
● Product traceability
Each batch is trackable, ensuring quality consistency and safety.
● Technical troubleshooting
If users encounter curing issues, leakage, or application concerns, professional engineers can offer quick on-site assistance when needed.
● Flexible customer service
- Faster claim resolution(online response in 5 minutes)
- Support for customized needs
- Stable long-term supply partnerships
This level of service is often unavailable from international brands, giving LK574 a clear advantage for industrial users needing fast, direct communication.
6. Typical Applications
LK574 is suitable for a wide range of industrial uses, including:
- Gearbox and transmission flange sealing
- Engine and pump metal housings
- Metal machinery casings
- Rigid flanged connections in general industry
- Hydraulic and pneumatic system housings
Its performance and versatility make it a dependable solution across automotive, manufacturing, energy, and machinery sectors.
