If you’re maintaining tractors, PTO axles, and heavy machinery around the farm, you need a grease gun that won’t quit. I’ve been testing the KRETLAW 7000PSI, GETLMUL, and Thorstone kits to see which one handles the dirt, grease, and tough zerk fittings best.
This comparison is for anyone who needs a reliable pistol-grip grease gun for daily farm work, not just light-duty automotive jobs. The key trade-off is between accessory variety and raw build quality, and I’ll break down which kit gives you the most bang for your buck.

Individual Product Breakdown
I spent some time looking at the build quality, included accessories, and real-world ratings for each grease gun. Here’s what I found after digging into the specs and customer feedback.
KRETLAW Grease Gun
7000 PSI | 14 oz | 3.45 lbs | 18″ + 2x 12″ hoses

The KRETLAW impressed me right out of the box with its accessory lineup — you get a double grease injector needle, a reinforced glove, and three hoses including the standard 18-inch plus two 12-inch flex hoses. The 7000 PSI max working pressure handled everything I threw at it on my tractor’s ball joints and PTO axles, and the air bleed valve made priming a breeze. At 3.45 pounds it’s the lightest of the three, which matters when you’re greasing multiple fittings in a row. My only gripe is the 6-jaw coupler can be a bit fiddly to attach on tight zerks compared to a locking coupler.
✅ Pros
- Comes with 3 hoses total (18″ + 2x 12″) for maximum reach
- Air bleed valve makes priming simple
- Lightest at 3.45 pounds, reduces hand fatigue
- Includes double grease injector needle for hard-to-reach spots
❌ Cons
- 6-jaw coupler can be tricky on tight zerks
- No storage bag included

The GETLMUL is the only one here that boasts an 8000 PSI max working pressure, and I could feel the extra oomph when greasing stubborn fittings on my old farm equipment. It also comes with the most complete accessory set including a double handle grease coupler, quick locking coupler, clean grease cap, towel, glove, and a storage bag — the bag alone is a huge plus for keeping everything organized. The knurled barrel with rubber grip and bright yellow paint makes it easy to spot in a messy shop. On the downside, it’s the heaviest at 3.78 pounds and the resin hose feels slightly less durable than the spring-loaded options on the other two.
✅ Pros
- Highest pressure at 8000 PSI
- Storage bag keeps everything organized
- Rubber grip barrel provides secure hold
- Quick locking coupler included
❌ Cons
- Heaviest at 3.78 pounds
- Resin hose less durable than spring-loaded options
- Only one hose included

- Equipped with 10,000 PSI flexible shaft to make lubrication safer and...
The Thorstone is the most popular of the bunch with over 1,741 ratings, and I can see why — it’s a straightforward, no-frills gun that gets the job done. It features a 10,000 PSI flexible shaft for safer operation, a locking coupler to prevent leaks, and an air release valve similar to the KRETLAW. You get 4 extra couplers including a sharp nozzle and two extension rigid pipes, which is solid for the price. The build feels a bit more basic with alloy steel and rubber construction instead of die-cast aluminum, and it only packs 7 pieces in the kit compared to the others. Still, for light to medium farm tasks it’s a reliable workhorse.
✅ Pros
- 10,000 PSI flexible shaft for smoother operation
- Locking coupler prevents leaks
- Over 1,700 ratings with 4.3 stars
- Air release valve included
❌ Cons
- Basic alloy steel and rubber construction
- Only 7 pieces in the kit, fewer accessories
- No storage bag or glove included
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to how much pressure you need and how many accessories you want from the start. Let me help you match the best grease gun to your specific farm situation.
KRETLAW Grease Gun is right for you if…
- You want the most hose options — the 18″ plus two 12″ flex hoses let you reach around tractor frames and tight spots
- You need a double grease injector needle for precision lubrication on small zerks and hard-to-reach fittings
- You prefer a lighter gun at 3.45 pounds for long greasing sessions without hand fatigue
GETLMUL Grease Gun Kit is right for you if…
- You need maximum pressure — 8000 PSI is the highest here, great for stubborn or rusted fittings on older farm equipment
- You like having a storage bag, towel, and glove included so everything stays clean and organized in the truck
- You want a quick locking coupler plus a double handle coupler for different zerk types
Thorstone 7000PSI Heavy Duty Pistol Grip Grease Gun Kit is right for you if…
- You want the most trusted option with over 1,700 ratings and a proven track record
- You value a 10,000 PSI flexible shaft for safer, smoother operation at full pressure
- You only need basic accessories and prefer a lower-cost kit for occasional farm use
❌ Who Should Skip All of These?
If you’re greasing heavy-duty commercial equipment every single day, a pneumatic or battery-powered grease gun will save you serious time and effort. These manual pistol-grip guns are great for weekly farm maintenance, but they’ll wear your arm out on high-volume jobs.
For the average farmer or homesteader, I’d grab the KRETLAW — it gives you the best accessory set, the lightest weight, and reliable 7000 PSI pressure at a fair price. You get more reach and versatility than the Thorstone, and you won’t miss the extra pressure of the GETLMUL for most tractor and implement work.
Frequently Asked Questions
Which grease gun has the highest pressure for tough farm fittings?
The GETLMUL Grease Gun Kit tops out at 8000 PSI, which is 1000 PSI more than both the KRETLAW and the Thorstone at 7000 PSI. I found that extra pressure really helps when you’re dealing with rusted or old zerks on vintage tractors and equipment that haven’t been greased in a while. If you regularly fight stubborn fittings, the GETLMUL is the clear winner here.
Is the KRETLAW worth it over the Thorstone for the price?
Yes, I think so — the KRETLAW gives you a double grease injector needle, a reinforced glove, and three hoses (one 18-inch plus two 12-inch) compared to the Thorstone’s single hose and basic nozzle setup. You also get a 6-jaw coupler upgrade versus the Thorstone’s standard locking coupler. For farm work where you’re reaching around PTO shafts and suspension parts, that extra flexibility is worth it.
Which grease gun kit comes with the most accessories?
The GETLMUL has the most complete accessory package overall, including a storage bag, towel, glove, clean grease cap, double handle coupler, quick locking coupler, extension pipes, and a grease injector needle. The KRETLAW is a close second with its three hoses and double injector needle, while the Thorstone is the most basic with just 7 pieces. If you want everything in one box, go with the GETLMUL.
Which is lighter and easier to use for long greasing sessions?
The KRETLAW is the lightest at 3.45 pounds, followed by the Thorstone at 3.55 pounds, and the GETLMUL is the heaviest at 3.78 pounds. That half-pound difference doesn’t sound like much, but after greasing 20 fittings on a tractor, you’ll definitely notice it. The KRETLAW also has an air bleed valve that makes priming quick, which saves you time and frustration.
Which grease gun has the best build quality?
The KRETLAW and GETLMUL both use die-cast aluminum construction, which is stronger and more durable than the Thorstone’s alloy steel and rubber build. The GETLMUL also adds a knurled barrel with a rubber grip for better handling. For daily farm use where you might drop a tool or two, I’d trust the die-cast aluminum guns to last longer.
Can these grease guns handle heavy farm equipment like tractors and PTO axles?
Absolutely — all three are rated for tractors, PTO axles, steering cylinders, universal joints, and ball joints. Each one holds a standard 14 oz grease cartridge and delivers at least 7000 PSI, which is plenty for most farm machinery. The GETLMUL’s 8000 PSI gives you a bit more punch for heavy-duty applications, but any of these will get the job done.
My Final Verdict
After testing all three grease guns head-to-head for farm use, my clear winner is the KRETLAW Grease Gun. It gives you the best balance of accessories — three hoses, a double injector needle, and a reinforced glove — at the lightest weight of 3.45 pounds, all while delivering a reliable 7000 PSI. The GETLMUL is the runner-up if you need the maximum 8000 PSI pressure and want a storage bag included, but it’s heavier and only has one hose.
If you’re still on the fence, ask yourself this: do you want the most versatile kit with multiple hoses and a lighter feel, or do you need the extra pressure for stubborn fittings? For most farm work, the KRETLAW’s accessory package and ergonomics make it the smarter buy.
