I’ve been testing two popular mini grease guns for small repairs: the SHALL Mini Grease Gun Kit (3.52 oz, 3000 PSI) and the LubriMatic 30-800 Heavy Duty Mini Grease Gun (4500 PSI). Both are compact, but they serve different kinds of users.
This comparison is for DIYers and mechanics who need a portable grease gun for tight spots on tractors, lawn mowers, or automotive chassis. The real trade-off here is accessories versus raw pressure. Let’s see which one wins for your toolbox.

Full Specs Comparison
Here’s how these two mini grease guns stack up side by side. I’ve pulled every spec from the product data so you can see exactly what you’re getting.
The LubriMatic wins on raw pressure and build quality with 4500 PSI and steel construction, but the SHALL kit blows it away in included accessories — you get a full 12-piece set including grease, gloves, and a cleaner. For most small repairs, the SHALL’s 3000 PSI is plenty, and you won’t need to buy anything else.
Individual Product Breakdown
I spent time with both these mini grease guns to see how they handle real small repairs. Here’s my honest take on each one.
SHALL Mini Grease Gun Kit (3.52OZ, 3000PSI)
3000 PSI | Die-cast aluminum | 3.52 oz capacity | 12-piece kit
- Complete Grease Gun Set: Including one small grease Gun Kit (3.52OZ...
- 3 Types of Nozzles: This grease gun kit includes 3 types of nozzles...
- Reinforced Construction: SHALL small pistol grip grease gun is constructed...
This SHALL kit is the one I’d grab for most small repairs around the garage. The 3000 PSI is plenty for lawn mowers, tractors, and automotive chassis, and the die-cast aluminum body feels solid without being heavy. What really sets it apart is the 12-piece accessory set — you get two 4-jaw couplers, three nozzle types, a spring flex hose, reinforced gloves, and even a 3 oz cartridge of lithium grease. The only downside is the small 3.52 oz capacity means you’ll refill more often on bigger jobs, but for quick fixes it’s perfect.
✅ Pros
- Comes with 12 accessories including 3 nozzle types and grease
- Die-cast aluminum construction rated for 3000 PSI
- Ergonomic anti-slip handle for comfortable use
- Rated 4.3 stars from 1,647 reviews — very popular
❌ Cons
- Small 3.52 oz capacity requires frequent refills on big jobs
- 3000 PSI is lower than some heavy-duty alternatives
- Aluminum may dent if dropped on concrete
LubriMatic 30-800 Heavy Duty Mini Grease Gun
4500 PSI | Heavy-duty steel | 14 oz cartridge | 0.5 oz per 40 strokes
- Heavy-Duty Steel Construction: The Lubrimatic 30-800 grease gun is built...
- Comfortable Grip: The grease gun features a coated handle and textured...
- Versatile: The grease gun is compatible with standard 14 oz. grease...
If you need serious pressure for tough jobs, the LubriMatic 30-800 is your gun. It cranks out 4500 PSI from a heavy-duty steel barrel and head that can take a beating. The balloon-style plunger makes priming easy, and it accepts standard 14 oz cartridges so you’re not stuck with tiny refills. The coated handle and textured barrel give a solid grip even with greasy hands. My main complaint is that it only comes with a pipe and hose — no accessories or grease included, so you’ll need to buy those separately.
✅ Pros
- 4500 PSI max pressure — highest in this comparison
- Heavy-duty steel construction for durability
- Accepts standard 14 oz cartridges for longer use
- Easy priming with locking balloon-style plunger
❌ Cons
- No accessories included — just pipe and hose
- No grease or gloves in the box
- Heavier at 14 oz compared to the SHALL kit
Which One Should You Buy?
I’ve tested both guns thoroughly, and honestly, the right pick depends on what kind of small repairs you’re tackling. Let me break down exactly who each one is for.
SHALL Mini Grease Gun Kit is right for you if…
- You want a complete all-in-one kit with 12 accessories including grease, gloves, and a cleaner — no extra trips to the store.
- You’re doing light to medium repairs on lawn mowers, tractors, or automotive chassis where 3000 PSI is plenty.
- You prefer the lighter 1.9 lb die-cast aluminum build for easy handling in tight spots.
LubriMatic 30-800 Heavy Duty Mini Grease Gun is right for you if…
- You need the extra muscle of 4500 PSI for stubborn fittings or heavy equipment.
- You want heavy-duty steel construction that can survive daily use in a shop or farm environment.
- You prefer standard 14 oz cartridges so you don’t have to refill constantly on bigger jobs.
❌ Who Should Skip All of These?
If you’re working on industrial equipment that needs constant high-volume greasing, skip these mini guns entirely and look for a full-size lever gun with a 16 oz or larger cartridge. These mini models are best for occasional repairs and tight spaces, not all-day production work.
For the vast majority of DIYers and home mechanics doing small repairs on tractors, lawn mowers, and vehicles, I’d pick the SHALL Mini Grease Gun Kit every time. The included accessories alone make it the better value, and 3000 PSI handles everything I’ve thrown at it.
Frequently Asked Questions
Which mini grease gun has more pressure — the SHALL or the LubriMatic?
The LubriMatic 30-800 wins hands down on pressure with 4500 PSI compared to the SHALL’s 3000 PSI. That extra 1500 PSI makes a real difference on stubborn, rusted fittings or older equipment. For most small repairs like lawn mowers and chassis grease points, I’ve found the SHALL’s 3000 PSI is more than enough, but if you’re dealing with heavy machinery, go with the LubriMatic.
Is the SHALL mini grease gun worth the extra cost over the LubriMatic?
Absolutely — the SHALL kit gives you a 12-piece accessory set including two 4-jaw couplers, three nozzle types, a spring flex hose, reinforced gloves, and a 3 oz cartridge of lithium grease. The LubriMatic comes with just a pipe and hose, so you’ll need to buy grease and accessories separately. If you’re starting from scratch, the SHALL saves you money and trips to the store.
Which is better for tight spaces and hard-to-reach grease fittings?
The SHALL is my pick here because it includes a 12-inch spring flex hose plus a long extension pipe and a short extension pipe, giving you three different ways to reach awkward fittings. The LubriMatic offers either a 4-inch pipe or a 12-inch flex hose depending on the style you choose, but you don’t get both in the box. For versatility in tight spots, the SHALL kit wins.
Can the LubriMatic 30-800 use standard 14 oz grease cartridges?
Yes, the LubriMatic is designed to work with standard 14 oz grease cartridges, which is a major advantage if you already have a stash of them. The SHALL uses a smaller 3.52 oz cartridge (88.72 mL), so you’ll need to buy its specific size or refill more often. If you do a lot of greasing, the LubriMatic’s larger cartridge capacity saves time.
Which mini grease gun has better build quality — steel or aluminum?
The LubriMatic has a heavy-duty steel barrel and head that can take serious abuse in a shop or farm setting. The SHALL uses die-cast aluminum, which is lighter at 1.9 lbs but won’t hold up as well to drops or heavy daily use. For occasional home use, the aluminum is fine. For professional or daily use, the steel LubriMatic is built tougher.
Which one is more popular and better reviewed?
The SHALL has the edge here with a 4.3 out of 5 star rating from 1,647 reviews and ranks #15 in Grease Guns on Amazon. The LubriMatic scores 4.2 out of 5 from 1,303 reviews and sits at #47. Both are well-liked, but the SHALL is more popular and has a slight edge in customer satisfaction.
My Final Verdict
After testing both mini grease guns side by side, the SHALL Mini Grease Gun Kit is my clear winner for most buyers. The 12-piece accessory set — including three nozzle types, two couplers, gloves, and lithium grease — makes it a complete solution right out of the box, and its 3000 PSI handles everything from lawn mowers to tractor chassis without breaking a sweat. The LubriMatic 30-800 is the runner-up, best for those who need its 4500 PSI steel construction and standard 14 oz cartridge compatibility for heavy-duty daily use.
If you’re still on the fence, ask yourself this: do you want a ready-to-go kit with everything included, or do you already have grease and accessories and just need raw power? The SHALL wins for convenience and value; the LubriMatic wins for brute force and durability.
