Review on CTA Tools 7790 Locking Coupler by Kevin Folsom

Revainrating 5 out of 5

Great addition to the Lincoln Grease Gun.

Bought to use with my new Lincoln grease gun. All I can say is that it is way better than a cheap grease gun with poor quality fittings. There is no comparison. Works incredibly well, you will NEVER have problems with "pressure traps" that make cheaper couplers difficult to remove after lubricating the Zerk fittings. The only downside is that it's difficult to use in tight spaces; but this clutch works very well with easy access fittings.

Pros
  • 3 jaw design for superior alignment and durability
Cons
  • Faulty
