Bolaxin Fluid Pump for Standard Quart Bottles, 3rd Hand Adapter, Transfer Gear Oil Transmission and Differential Fluid

Other than the small drip that comes from the tip be cause it doesn't have a clamp holding the hose to the tip, this is wonderful. Fits mobil1 gear oil bottles perfect and the tip holds it in various sized holes to free up two hands for pumping. I used it on my transmission, transfer case, and both front and rear differentials without a problem so it has paid for itself many times over.

Easy to use and it works efficiently.

Works great!

Pump worked perfectly for doing CVT fluid replacement. The small arms on the fill nozzle do nice job keeping the tube in place. Note that the screw top is made to fit quart bottles with small caps - but not the wide mouth bottles that are also common. Pump still works even if you can’t screw it on the bottle.

I bought this for differential fluid changes. I don't consider this a high-use, long-term tool. I expect that it will last for 2-3 uses only. Pros: good volume per pump stroke. Reasonable price. Cons: cap is attached to the piston with a tension fit - easily pops off when pumping high lubricity fluids. With repeated use, the butterfly adapter can break and fall into a differential housing. This is specifically for a 28mm bottle top - my preferred gear oil only comes in a 23mm bottle.

Worked great to pump fluid into transaxle. Or and hard to reach spot you vant get bottle into

Looks good, haven’t used yet.

I would recommend this to one who is looking to buy as it is very smooth and not much pressure to be applied
