LockNLube® Grease Couplers and more!

End Greasing Frustration

The LockNLube® Grease Coupler locks onto the Zerk fitting with four jaws made from spring-steel, and are easily disengaged using a thumb lever via a sliding sleeve. When locked, a leak-proof seal is created, and the connection is positive and rigid, preventing the coupler from coming loose and breaking the seal.

Key features include:

  • No leaking once locked on
  • Will not release under pressure, and is rated up to 10,000 PSI
  • 1/8” NPT female thread is compatible with most grease guns
  • Works on all Zerk fittings: SAE and Metric
  • Hands-free greasing. Once locked on, both hands are free to operate your grease gun
  • Easy to rebuild with free replacement seal and jaws included in purchase
  • Works for both heavy-duty use or occasional greasing
  • Simply depress trigger to release, even under pressure

Check out these couplers and many other tools to help improve your repairs and maintenance.
