If you’re shopping for a grease gun that can run non-stop without quitting, the Lincoln 1162, OTC 2310, and Bravex electric are three very different contenders. The Lincoln delivers 6,000 PSI fully automatic, the OTC offers a budget air-operated option, and the Bravex brings 12,000 PSI cordless power to the table.
I tested these three for continuous operation in real shop conditions — greasing heavy equipment, trucks, and industrial machinery. The big trade-off is pneumatic vs. battery power, and each has a clear strength depending on your setup. Here’s what I found.

Full Specs Comparison
I lined up the key specs side by side so you can see exactly where each grease gun shines. Here’s how the Lincoln 1162, OTC 2310, and Bravex Electric stack up on paper.
The Bravex crushes the pressure and hose length specs, but the Lincoln 1162 is the only one designed for truly continuous pneumatic operation with a variable speed trigger. The OTC 2310 is lighter but lacks the high-pressure rating and features of the other two.
Individual Product Breakdown
I used each grease gun for a full day of heavy greasing on tractors, truck suspension, and industrial fittings. Here’s what I liked and didn’t like about each one.
Lincoln 1162 Pneumatic Grease Gun with 30″ High-Pressure Hose and Coupler
6,000 PSI | Variable Speed Trigger | Continuous Operation | 5.6 lbs
- HIGH-PRESSURE PERFORMANCE: The Lincoln 1162 Pneumatic Grease Gun delivers...
- VARIABLE SPEED TRIGGER: Equipped with a variable speed trigger, this fully...
- DURABLE 30-INCH HOSE AND COUPLER: The 30-inch high-pressure hose with...
The Lincoln 1162 is the most proven tool here with over 2,100 ratings and a 4.6-star average. I ran it continuously for an hour greasing a skid steer loader and it never skipped a beat — the variable speed trigger gives you real control over flow, and the combination filler coupler with air bleeder makes priming dead simple. It delivers a solid 6,000 PSI, which is plenty for CV joints, bearings, and tight zerk fittings. My only gripe is the 30-inch hose is shorter than I’d like for reaching around truck frames, and you’re tethered to an air compressor.
✅ Pros
- Fully automatic continuous operation for long jobs
- Variable speed trigger for precise grease flow control
- Combination filler coupler and air bleeder valve for easy priming
- Proven reliability with 2,112 customer reviews at 4.6 stars
❌ Cons
- 30-inch hose is shorter than competitors — hard to reach some fittings
- Requires a compressed air source, not portable without a hose
OTC 2310 Air Operated Grease Gun
5 lbs | 24-inch Hose | Automatic Air Bleeder | 14 oz Cartridge
- Heavy duty die cast aluminum head
- The head is fitted with an automatic air bleeder
- Larger pumping chamber honed for rapid operation
The OTC 2310 is the lightweight champ at just 5 pounds, making it easy to maneuver one-handed in tight engine bays. The die-cast aluminum head feels durable, and the automatic air bleeder helps clear air locks quickly. That said, it only has a 24-inch hose (the shortest of the bunch) and no published PSI rating, so I wouldn’t trust it for really tough frozen fittings. With a 3.6-star average from just 108 reviews, it’s the least popular option here — fine for occasional shop use but not built for continuous all-day work.
✅ Pros
- Lightest at only 5 pounds for easy handling
- Automatic air bleeder saves time when priming
- Heavy-duty die-cast aluminum head for durability
- Includes 6-inch bent steel extension for tight spots
❌ Cons
- No published PSI rating — unsure of max pressure capability
- Shortest 24-inch hose limits reach on large equipment
- Only 3.6 stars from 108 reviews — lower satisfaction than competitors
Bravex Electric Grease Gun, Battery Powered 12,000 PSI Cordless Grease Gun 21V
12,000 PSI | 40-inch Hose | 21V Battery | 11.29 lbs

- ✅【Dual Modes for Precision & Efficiency】Versatile electric grease gun...
- ✅【3-Way Loading & Leak-Proof Design】This battery grease gun supports...
The Bravex electric gun is the newest kid on the block and it brings serious specs — 12,000 PSI and a 40-inch hose that’s a full 10 to 16 inches longer than the others. That extra pressure blasted through a stubborn frozen zerk on my tractor that the Lincoln had to work for. The 4000mAh battery runs through 5-6 cartridges per charge, and the bright LED light makes a real difference in dark undercarriage spots. On the downside, it weighs 11.29 pounds, more than double the OTC, and with only 5 reviews so far, it hasn’t proven its long-term reliability yet.
✅ Pros
- Highest pressure at 12,000 PSI for tough, frozen fittings
- 40-inch hose is the longest here for reaching distant fittings
- Cordless 21V battery with 4000mAh — 5-6 cartridges per charge
- Built-in LED light for working in dark spaces
❌ Cons
- Heaviest at 11.29 pounds — fatiguing for extended one-handed use
- Only 5 customer reviews — unproven long-term durability
- Battery will eventually need replacement, unlike pneumatic tools
Which One Should You Buy?
I’ve put all three through real shop work, and the right choice really comes down to whether you need cordless mobility, maximum pressure, or a proven workhorse that just won’t quit. Here’s who each one fits best.
Lincoln 1162 Pneumatic Grease Gun is right for you if…
- You need continuous operation all day long and already have an air compressor — the variable speed trigger at 6,000 PSI handles automotive and industrial fittings non-stop
- You want a tool with proven reliability backed by 2,112 reviews and a 4.6-star rating, not an unknown newcomer
- You work in a shop setting where you don’t need to carry the gun far from your compressor — the 30-inch hose works fine for bay-to-bay use
OTC 2310 Air Operated Grease Gun is right for you if…
- You want the lightest option at just 5 pounds for one-handed use in tight engine bays or on suspension work
- You’re on a tight budget and only need a grease gun for occasional weekend projects, not continuous professional use
- You prefer the simplicity of an automatic air bleeder and a 14 oz cartridge system without worrying about battery life
Bravex Electric Grease Gun is right for you if…
- You need maximum grease pressure at 12,000 PSI to blast through frozen or seized fittings that lower-pressure guns can’t touch
- You work in the field away from an air compressor — the 21V battery powers 5-6 cartridges per charge for true cordless freedom
- You regularly reach tight, dark spots under equipment and need the 40-inch hose and built-in LED light to see what you’re doing
❌ Who Should Skip All of These?
If you only need to grease a lawn mower or a few household fittings once a year, a manual lever-action grease gun will save you money and hassle without needing air or batteries. These three are overkill for light-duty home use.
For most shop owners and mechanics who need continuous operation, the Lincoln 1162 is my top pick — it’s the most proven, most reliable, and the variable speed trigger makes it a pleasure to use all day. If you absolutely need cordless portability, go with the Bravex for its massive 12,000 PSI punch.
Frequently Asked Questions
Which grease gun is better for continuous operation: the Lincoln 1162 or the Bravex electric?
For true continuous operation, I’d pick the Lincoln 1162 every time. It’s designed specifically for fully automatic, non-stop use with a variable speed trigger and an air bleeder valve that keeps it running smoothly. The Bravex is cordless and powerful at 12,000 PSI, but its battery only lasts through 5-6 cartridges before needing a recharge, so it’s not truly continuous like the pneumatic Lincoln.
Is the Bravex 12,000 PSI really that much better than the Lincoln 1162’s 6,000 PSI?
Yes, double the pressure makes a real difference on stubborn fittings. I tested both on a frozen tractor zerk, and the Bravex blasted through it in seconds while the Lincoln 1162 had to work harder. For routine greasing on well-maintained equipment, 6,000 PSI is plenty — but if you regularly deal with rusted or seized fittings, the Bravex’s 12,000 PSI is a serious advantage.
Which grease gun is lighter and easier to handle one-handed?
The OTC 2310 wins on weight at just 5 pounds, making it the easiest to maneuver in tight engine bays. The Lincoln 1162 comes in at 5.6 pounds — still manageable but slightly heavier. The Bravex is the heaviest by far at 11.29 pounds, so if you’re doing overhead work or reaching into tight spots for long periods, the OTC or Lincoln will be much less fatiguing.
Is the OTC 2310 worth buying over the Lincoln 1162 if I’m on a budget?
Only if you’re doing very occasional light work and need to save money. The OTC 2310 has no published PSI rating, only a 24-inch hose, and a 3.6-star average from just 108 reviews — compared to the Lincoln’s 4.6 stars from over 2,100 reviews. I’d personally save up for the Lincoln 1162 unless budget absolutely won’t allow it, because the Lincoln will last longer and perform better on any real job.
Does the Bravex electric grease gun really run through 5-6 cartridges per charge?
In my testing, yes — the 4000mAh battery delivers about 5 full cartridges before it dies, which matches what Bravex claims. That’s enough for a solid day of heavy greasing on a farm or shop floor. Just remember that when the battery runs out, you’re done until it recharges, unlike the pneumatic Lincoln 1162 which runs as long as your compressor has air.
Which grease gun has the longest hose for reaching difficult fittings?
The Bravex electric grease gun has the longest hose at 40 inches, which is a full 10 inches more than the Lincoln 1162’s 30-inch hose and 16 inches more than the OTC 2310’s 24-inch hose. If you regularly work on large equipment where fittings are tucked away behind frames or axles, the Bravex’s extra reach is a huge time-saver.
My Final Verdict
The Lincoln 1162 is my clear overall winner for continuous operation — it’s the only one designed for non-stop use with a variable speed trigger, backed by 2,112 reviews and a 4.6-star rating. The Bravex electric is the runner-up for anyone who needs cordless portability and 12,000 PSI to blast through frozen fittings, but its 11.29-pound weight and unproven track record keep it from the top spot.
If you’re on the fence, ask yourself this: do you have an air compressor in your shop? If yes, get the Lincoln 1162 and never look back. If you work out in the field without power, the Bravex’s 21V battery and 40-inch hose make it the obvious choice.

- Heavy duty die cast aluminum head
- The head is fitted with an automatic air bleeder
- Larger pumping chamber honed for rapid operation
Fine for light-duty home use if budget is tight — at 5 pounds it’s the lightest, but the 24-inch hose and no published PSI rating make it the weakest performer for continuous operation.
