Loctite LOC26774 Thread Sealant Threadlocker 250ml

Product Description

The LOCTITE LOC26774 is a 250ml bottle of 266 Threadlocker thread sealant formulated for securing and sealing threaded fasteners. This anaerobic adhesive cures in the absence of air and prevents loosening caused by vibration, shock, and thermal cycling. It is used on metal threaded assemblies in HVAC, plumbing, and mechanical systems where a reliable, permanent thread lock is required. Licensed mechanics, HVAC technicians, plumbers, and pipefitters apply this product during equipment assembly and field repair work where fastener retention and thread sealing are critical.

The LOC26774 threadlocker is suited for use on threaded metal fasteners in residential and commercial applications. Typical install scenarios include securing bolts, studs, and fittings on HVAC equipment, pumps, compressors, and piping assemblies where vibration and pressure fluctuations can cause fastener migration or joint leakage. The 250ml bottle size is appropriate for shop use and higher-volume field service operations.

Key Features

• 250ml bottle provides sufficient volume for shop or high-frequency field use
• Anaerobic cure mechanism activates on metal surfaces in the absence of air
• Designed to prevent loosening of threaded fasteners under vibration and thermal cycling
• Serves dual function as both a threadlocker and thread sealant
• Sold as individual unit with a minimum order quantity of one

Compatibility

Designed for use on metal threaded fasteners and assemblies where an anaerobic thread-locking and sealing compound is specified.

Installation Notes

Application is typically performed by HVAC technicians, plumbers, pipefitters, or mechanical assemblers. Ensure mating surfaces are clean, dry, and free of oils or contaminants before applying the sealant. Allow adequate cure time before applying load or pressure to the assembly, following the manufacturer cure schedule for the ambient temperature. Refer to applicable codes such as the IFGC or IPC when using thread compounds on gas or water piping systems to confirm the product is listed and approved for that service.
