Grease Gun Coupler Adapter, 14000 PSI

A greasy zerk tucked behind a control arm or under a mower deck is hard enough to reach without having to hold the tip in place. We built this coupler adapter with hardened jaws and a thick seal so it locks onto the fitting and stays there while you pump. Your grease gun hose stays attached; grease goes into the joint instead of pooling on the casing.

What this one is built to do

Locking jaw design

The internal steel jaws bite onto the nipple of the fitting and hold fast under pressure. You snap the collar forward to grab, grease the bearing, and pull the lever back to release the grip without prying.

Finding hidden zerks

The outer sleeve pulls back so the guide ring sits wide open while you feel around blind suspension points or tractor pivots. Once the center seats over the grease nipple, the collar snaps shut.

Zinc coated steel body

We machine the adapter body from alloy steel and coat it in zinc to shed dirt, grime, and grease. It handles the daily knocks of sliding across gravel driveways and living in the bottom of a steel tool chest.

Standard pipe threads

The adapter threads directly onto standard grease gun extensions and flexible whip hoses. Keep a rag handy on the bench to wipe the threads clean before you spin it into your grease gun setup.
