Park Tool Threadlockers.
- Threadlockers lock threaded assemblies and keeps them from loosening over usage. Formulas are oil tolerant and both compatible with steel, aluminum, and carbon fiber but are not recommended for titanium fasteners.
- TLR-1 is blue medium strength
- TLR-2 is red high strength
- Park Tool AP-1 Adhesive Primer must be used to prep all components, fasteners, and carbon fiber surfaces prior to application of Park Tool threadlockers or retaining compound. Failure to do so could result in permanently bonded parts
