Park Tool - TLR-1 - Threadlocker - Blue - Medium

TLR-1 offers performance comparable to Loctite 242 and 243, while TLR-2 rivals Loctite 262 and 263. These adhesives are compatible with steel, aluminum, and carbon, but we recommend against using them on titanium fasteners.

To ensure optimal adhesion to carbon surfaces, we recommend using Park Tool AP-1 Adhesive Primer. This product effectively prepares all parts, fasteners, and carbon surfaces before adhesive application, guaranteeing a strong and durable bond. TLR-1-01, in blue, offers medium strength.
