PERMABOND HH131
Harmonization Code : 3506.10.00.00 | Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg

Main features
- High-Strength High-Temperature Threadlocking
- DVGW/KTW-BWGL Approval Scope
- Thread Lubrication and Vibration Resistance
Product Description
Permabond® HH131 is a high-strength, anaerobic threadlocker and sealant engineered to deliver exceptional performance in extremely high-temperature environments. It cures reliably in the absence of air between tight-fitting metal components, making it ideal for locking bolts, nuts, and screws that require permanent assembly. In addition to its temperature resistance, HH131 lubricates threads to facilitate easier assembly and provides superior resistance against harsh chemicals, vibration, and environmental factors.
Key features
- High temperature resistance: Specially formulated to maintain structural integrity and high breakaway torque even in environments subject to elevated temperatures.
- Industry approved: Holds DVGW Approval for Gas applications and is KTW-BWGL Drinking Water Compliant, ensuring safe use in regulated utility systems.
- High strength & vibration resistance: Provides a permanent, very high-strength lock (Breakaway torque 27 N-m) that effectively prevents fasteners from loosening due to vibration or shock.
Applications / Suitable for
- Permanent assembly of bolts, nuts, and screws operating in high-temperature environments
- Gas and drinking water systems requiring DVGW and KTW-BWGL compliance
- Assemblies requiring vibration resistance and lubrication during installation
