Introducing the LockNLube Grease and Air Couplers

Introducing the LockNLube grease and air couplers.


Sometimes two hands are not enough!  LockNLube couplers lock onto the zerk or air stem for a secure handsfree connection.  Stop by Warehouse Supply and check out the new line of LockNLube products.  LockNLube products make equipment maintenance easier, faster and more efficient!


LockNLube Grease Coupler:           LockNLube Grease Coupler: at warehouse supply inc. in Lasalle CO

 The LockNLube® Grease Coupler is compatible with all grease guns and grease fittings. It does not leak once locked on and will not pop off under pressure. No hands are needed to align or hold the coupler in place while greasing. You have both hands free to operate your grease gun and know that the grease will go in, not on, your machine. Guaranteed!


It has a unique sliding sleeve, activated by a thumb lever. The sleeve locks the four spring-steel jaws onto the zerk fitting and releases the jaws by pushing on the thumb lever. When the jaws are locked onto the zerk, a leak-proof seal is created. The locked connection is positive and rigid, preventing the coupler from coming loose and breaking the leak-proof seal. If a fitting becomes pressurized, especially a recessed one, just depress the thumb lever and release the coupler.

The LockNLube® Grease Coupler is fully rebuildable. If it starts to leak, you simply replace the seal and jaws, and it is as good as new. See our tutorial here. We include a free rebuild kit with every coupler that we sell. Additional rebuild kits are also available from Warehouse Supply, Inc.

LockNLube Grease GunLockNLube Grease Gun at Warehouse Supply, inc. in Lasalle, CO:

The LNL153 is a heavy-duty grease gun that gets the job done! We include a high-quality 20” hose, in-line Hose Swivel, and LockNLube® Grease Coupler. We guarantee that the coupler locks on and won’t leak. When you’re done greasing just push the thumb lever down to release.

Our Loop & Lock storage feature allows you to secure the coupler when not in use. It also creates a loop in the hose easily used for storage or carrying. This means no more greasy mess on your clothes, truck, and shop from hoses flying around when you pick up the grease gun.

The rubber grip and shaped handle make this grease gun comfortable in the hand. Rated up to 5,000 PSI, this gun puts out plenty of pressure to handle sticky fittings. Includes an air bleeder valve so you can load and prime the gun easily.
