Park Tool TLR-1 Thread Locker
Medium strength blue compound designed for the locking and sealing of threaded components which require normal disassembly with standard hand tools.
This product is oil/grease tolerant, cures when confined in the absence of air between close fitting metal surfaces, protects threads from rust and corrosion and prevents loosening from shock and vibration.
Common uses: crank arm bolts, chainring bolts, bottom bracket cups, etc.
Some painted surfaces can be sensitive to thread lockers, especially lighter colors. Test first on an inconspicuous area to see if it causes a stain or discoloration. Clean off any excess from painted surfaces immediately.
