Permabond HH131 (50ml)

Permabond HH131 is a very high-temperature resistant, high-strength anaerobic threadlocker and sealant designed for permanent assembly. Offering a red, high-viscosity finish, HH131 is an ideal solution for locking bolts, nuts, and screws that require maximum thermal stability and resistance to vibration.

With exceptional chemical resistance and high shear strength, Permabond HH131 provides a durable bond on mild steel, zinc, and aluminium, ensuring joint integrity in demanding industrial environments. This threadlocker lubricates threads for easier assembly and prevents corrosion, while its 100% solids formula ensures it is both environmentally friendly and effective at sealing against leaks.

HH131 is ideal for high-stress applications as it can fill gaps up to 0.3mm and reaches handling strength on steel in approximately 15 minutes at room temperature.
