Which grease gun to buy: lever, pistol grip or air?
Buy a pistol-grip gun for the bench and a lever gun for the awkward, seized points on a press or a loader. Add an air-operated gun only when you already buy grease by the pail. The specification that should decide it is not the pressure printed on the box — it is how much grease one stroke puts out, and only some makers publish that.
The number that decides it: strokes per ounce
One ounce per 40 strokes is what TOPTUL publishes for the JJBA1401 pistol grip, and it is the most useful figure on any grease gun sheet. It converts the job into something a fitter can count: a standard 14 oz cartridge is 560 strokes, so a small sealed bearing gets a counted five or six, not a squeeze until grease weeps out of the seal.
That matters because over-greasing is the common failure, not under-greasing. Push too much into a sealed bearing and the seal lets go, which puts you back on the machine within weeks. It is also expensive: on a Pakistani oil marketer's June trade list, EP 2 grease runs close to Rs 2,000 a kilo, so grease pumped onto the floor is a real line in the consumables budget. A gun with a published output lets you write "six strokes" on a lubrication card instead of "grease weekly".
Read the pressure figure twice
Because the number in the marketing is usually the burst pressure, and the one that does the work is the maximum working pressure. Total's THT111051 is sold as a "10000psi" gun; its own sheet gives 10,000 psi as the burst figure and 4,500 psi as the working pressure, which is the same as the pistol grip above. Nothing wrong with the gun — but it is not twice the tool.
The genuinely high-pressure hand gun in this group is TOPTUL's JJAA1402 lever type: 6,000 psi maximum working, 10,000 psi burst, with a two-stage variable stroke so you can switch from volume to pressure when a nipple will not take grease. That is the one for a press, a loader pin or anything that has been standing.
| Gun | Action | Max working pressure | Loading | Buy it for |
|---|---|---|---|---|
| JJBA1401 | Pistol grip, one-handed | 4,500 psi | 14 oz cartridge, filler pump or 400 cc bulk | Counted shots at the bench |
| JJAA1402 | Lever, two-stage variable stroke | 6,000 psi | 14 oz cartridge or 400 cc bulk | Seized nipples, press and loader pins |
| JJCA14014 | Air-operated, continuous flow | 3,600 psi at 90 psi shop air | 14 oz cartridge or 400 cc bulk | Long rounds, many nipples |
When the air gun pays for itself
When the pumping, not the grease, is what costs you. The JJCA14014 runs a 40:1 pressure ratio: TOPTUL's range is 60 to 150 psi of shop air in for 2,400 to 6,000 psi out, with 90 psi in and 3,600 psi out as the recommended working point. It still takes a standard 14 oz cartridge, so it is not a bulk system — it is the same round done without a sore forearm.
If your round is a dozen machines and two trucks, two hand guns cover it: the pistol grip on the bench for counted shots, the lever gun in the toolbox for everything that fights back. The air gun earns its place at plant scale, where a fitter walks a hundred nipples in a shift.
Trade prices are quoted per part number rather than listed, so send the ones you want: Vesprr Tools will price the JJBA1401, JJAA1402 and JJCA14014 together, and the catalogue search shows what else is on the shelf against them.
