Top 5 Best Grease Gun Coupler Reviews

Let’s look at some of the best 5 and get into their details!

#1. LockNLube Grease Gun Coupler locks onto Zerk fittings.

The LockNLube XL model presents an impressive 3.6-inch longer barrel, which exceeds the regular LockNLube model by a notable 2 inches. This extended length proves invaluable when confronted with deeply recessed oil fixtures, facilitating the access to rigid fittings tucked away in areas such as axles, U joints, shielded PTO shafts, harvester heads, and more.

When attached, this tool eliminates the need for manual pumping of the grease gun, allowing you to effortlessly apply lubrication. Despite its longer reach, the outer diameter is only slightly larger, merely 1 mm, in comparison to the standard LockNLube grease coupler model.

Designed with compatibility in mind, it features a 1/8 NPT thread that fits most grease fittings and is a suitable match for a wide range of grease guns. Additionally, the four rubber jaws are readily replaceable, ensuring long-term use without the need for constant replacement. What sets it apart is its reliable locking mechanism that prevents leaks and ensures it stays securely in place, even when subjected to high-pressure conditions.

#2. DEWALT 20V MAX Cordless Grease Gun.

Here’s why the DEWALT model deserves the top spot—it currently holds the highest rating in the market. With a remarkable capacity of 10,000 max psi, this machine stands out. Its 42-inch long flexible hose, featuring spring guards at the nipple, proves exceptionally practical. Although it leans on the heavier side, the no-mar foot design compensates for this as it allows for easy resting on flat surfaces.

This outstanding tool not only boasts a powerful motor and a high-volume pump but also comes equipped with a bright LED for illuminating hard-to-reach fittings in low-light conditions. Moreover, the pump is fitted with a screen cover to prevent dirt accumulation.

One common frustration with battery-powered grease guns is rapid battery drainage, but not with the DCGG571M1. Its 20V lithium-ion battery enables you to tackle 16 cartridges on a single charge, delivering an impressive five times more working time. There are very few aspects to criticize about this model. It has garnered praise for its user-friendliness, even from those with limited experience using grease guns.

Admittedly, it may come with a slightly higher price tag compared to other brands. Nevertheless, the DEWALT DCGG571M1 undoubtedly justifies its cost through exceptional performance, robust construction, durability, and ease of use. It’s a worthwhile investment for those seeking top-tier performance in a grease gun.

In summary, this Lincoln model proves its mettle by offering reliable performance even for moderate jobs, making it well-suited for tough lubrication tasks.
