Park Tool RC-1 is used to prepare non-threaded parts such as bottom bracket cups, sealed bearings, and other press fit components. RC-1 expands and hardens as it cures, filling gaps and ensuring secure installation.

Not recommended for threaded applications
NOTICE: When retaining compound or threadlocker is used on carbon fiber frames or components, adhesive primer such as Park Tool AP-1 must first be applied to all component, fastener and frame surfaces. Failure to do so could result in permanently bonded parts.
CAUTION: Some painted surfaces can be sensitive to threadlockers, retaining compounds and primers. Test first on an inconspicuous area to see if it causes a stain or discoloration. Clean off any excess from painted surfaces immediately.
