LOCTITE® 648

Features and Benefits

LOCTITE 648 is a low viscosity, high strength retaining compound with high temperature resistance. Ideal for retention of parts with a clearance or interference fit.
LOCTITE® 648 is a green, fluorescent, low viscosity, high strength, urethane methacrylate acrylic, anaerobic retaining compound designed for bonding cylindrical fitting parts. It prevents loosening and leakage from shock and vibration. Typical applications include holding gears and sprockets onto gearbox shafts and rotors on electric motor shafts. It provides robust curing performance.
  • High strength on all metals, including passive substrates (e.g. stainless steel)
  • Proven to be tolerant of minor contamination due to industrial oils
  • High temperature resistance
  • Designed for bonding cylindrical fitting parts
  • WRAS Approval (BS 6920): 0808532
  • DVGW Approval (EN 751-1): NG 5146C00236
  • P1 NSF Reg. No.: 148350
