Loctite 234345 High Temp Threadlocker 10 Ml Tube Blue

Product Description

The LOCTITE 234345 is a heavy duty, high temperature threadlocker in the Tight 8060 series, supplied in a 10 mL tube. It is a dimethacrylate ester-based liquid compound designed to lock and seal threaded fasteners against vibration loosening and leakage. With a shear strength of 1300 psi and a temperature rating of 298.4 degrees F, it is suited for demanding mechanical assemblies where standard threadlockers fall short. The blue color indicates a medium-strength, removable formulation. Curing time is 24 hours. Licensed trades including HVAC mechanics, pipefitters, and mechanical contractors apply this product during equipment installation and maintenance.

The LOCTITE 234345 is appropriate for use on threaded fasteners in high-heat environments such as HVAC equipment, pumps, compressors, and industrial mechanical systems. The high temperature rating makes it a fit for applications near heat exchangers, motor mounts, and exhaust-adjacent hardware. It is used in both residential and commercial mechanical service work wherever fasteners are subject to elevated operating temperatures and vibration. The liquid form allows it to wick into assembled threads as well as pre-applied use.

Key Features

• High temperature rating of 298.4 degrees F for use in thermally demanding assemblies
• 1300 psi shear strength provides reliable hold under mechanical stress
• Dimethacrylate ester base chemistry for thread-penetrating liquid application
• 24-hour full cure time; blue color indicates medium-strength removable grade
• 10 mL tube container for controlled dispensing and jobsite portability
• Flash point of 172.04 degrees F; store and handle away from open flame

Compatibility

Designed as an OEM-style threadlocking compound for metal threaded fasteners in high-temperature mechanical, HVAC, and industrial service applications.

Installation Notes

Applied by HVAC technicians, pipefitters, and mechanical service trades during fastener assembly or reassembly. Clean and degrease threads before application to ensure proper adhesion and cure. Allow the full 24-hour cure time before subjecting the assembly to full load or heat. Follow applicable safety data sheet guidance for ventilation and skin contact when handling liquid anaerobic adhesives.
