This bundle includes the LockNLube Grease Coupler, a high-quality 20" whip hose and our 10,000 PSI rated hose swivel. You also get a LockNLube Rebuild Kit for free if you ever need to replace the seal or jaws in your coupler.
We recommend installing the swivel at the opposite end of the hose from the coupler. This gives you all of the functionality, but doesn't increase the size of the coupler at the working end. If your grease gun does not have 1/8" NPT threads at the base end (some manufacturers have changed their threads to force the purchase of one of their branded hoses) you can always install the swivel directly behind the coupler.
