Permabond AA001310250B0101, HH131 High Temperature Threadlocker, 250ml Bottle, Case of 4
Permabond HH131 High Temperature Threadlocker, 250ml Bottle, Case of 4
Permabond HH131 is a high-strength, very high temperature resistant anaerobic threadlocker and sealant that cures in the absence of air between close-fitting metal parts. It is formulated for permanent locking of bolts, nuts, and screws in assemblies that must withstand elevated temperatures — making it the preferred choice for engines, exhaust systems, industrial machinery, and any application where standard threadlockers would fail under heat. Sold as a case of 4 x 250ml bottles.

Frequently Asked Questions
What makes HH131 different from standard threadlockers?
Permabond HH131 is specifically formulated for very high temperature resistance, making it suitable for applications where standard anaerobic threadlockers would soften or lose holding strength under heat. It is a permanent-grade threadlocker intended for assemblies that will not need to be disassembled — such as engine components, exhaust hardware, industrial machinery fasteners, and high-heat manufacturing equipment.
How does anaerobic curing work?
Anaerobic adhesives cure only in the absence of air (oxygen) and in the presence of metal ions. When HH131 is applied between two close-fitting metal parts and the joint is assembled, oxygen is excluded and the adhesive polymerizes to form a rigid, high-strength bond. It will not cure on surfaces exposed to air, which gives it a practical open time for assembly before the joint is closed.
Is HH131 suitable for permanent or removable applications?
HH131 is a high-strength, permanent-grade threadlocker designed for fasteners that require permanent locking and will not need routine disassembly. For applications requiring occasional removal, a medium-strength anaerobic threadlocker would be more appropriate. Consult the Permabond TDS for specific breakaway and prevailing torque values.
Why is HH131 sold as a case of 4 x 250ml bottles?
The 250ml bottle size is suited for production and maintenance environments with regular threadlocker usage. Purchasing as a case of 4 reduces per-unit cost and ensures supply continuity for assembly lines, maintenance departments, and industrial operations where HH131 is used routinely on high-temperature fastener applications.
