kweiny Pneumatic Fluid Extractor Drainers for Automotive Brake and Clutch and Power Steering Fluid

The media could not be loaded. Could not be easier to use. Simply hook it to your compressor via quick connect, set around 20 psi, then open the valve. The pump works smoothly and can create a considerable vacuum. I used it to flush my power steering on my 2000 suburban. Took the reservoir cap off, put some tape over the reservoir neck, poked a hole with a knife, then fed the like from this pump in and ran it. Easy. You could definitely make something like this yourself but for this unit only being 25 dollars, I'd say it's definitely worth a buy.

I was open minded when purchasing this product figuring it may work and it might not and be headed for the trash. The plan for this device is for fluid changes in riding mower hydrostatic transaxle, antifreeze coolant container, brake & power steering fluid and alike. I was not ready for its first job so I took a clean bottle of Mobil 1 full synthetic 10w30 (room temp) and extracted it from the container and it worked perfectly. So basic knowledge is warm / hot oil flows easily and this reinforces to me that this device will accomplish the anticipated tasks to come. I tailored the device by removing the inlet air fitting and connecting a small air regulator so as to reduce the operating 20psi per the documents that came with the unit. The air inlet fitting that was attached to it was clearly overkill for the 20 psi operating pressure and the regulator will allow the ability to monitor and adjust as necessary.Also added a S hook along with the provided hook to hang up and support the product during use. As of now I know it works and can recommend this product and will update & adjust the knowns if necessary. At a under $25 price point to the front door is low risk and the turkey baster thing sucks !

Used it to prime a diesel injection pump and it worked great.

Not great suction, it will not pull fluid through brake lines no matter how high the incoming air pressure is. But it does pull enough suction to help prevent air from flowing back into brake calipers when bleeding them traditionally. And it prevents a mess from the bleeder valve. It is still useful for removing fluid from reservoirs/differentials/transfer cases and that sort of thing. It's handy to have around. Just not a replacement for a brake bleeder pump.

This worked great Honda Accord automatic transmission.Just put in dipstick hole and suck out 2 1/2 qts of old transmission fluid and put 2 1/2 qts back in . I do it every other oil change every 10000 miles car has 103000 miles fluid looks nice and red still

I am presently sitting on a Kweiny but cannot say I have been entirely satisfied. I would say that it really sucks well. But, I don't feel that I have been shafted, however, I feel that the kweiny is a bit small. Fortuitously I believe the suction head could be better with a larger can on the bottom and this could readily be done with the Kweiny. My sole concern is that it seems under certain circumstances to have an unwanted discharge of brake fluid. This unwanted emission causes me some health concern as it sprays wontanly into the air and surrounding environs. This is remedied easily by catching the outflow in a soft sponge rubber tied over the outlet. Although the kweiny is predominately made of good metal it has no real trigger mechanism. It is either turned on or turned off. This would be a concern but, it is easy to keep turned on as it not too demanding. At the end of the day I guess Ill just live with it's shortcomings. At least it is affordable. On a side note, the suction orifice appears on the face of it to possibly be degraded by brake fluid.

I was skeptical at first, I've used the hand operated vacuum pumps for years. I broke down and picked one up since it wasn't very pricey, and I was very impressed with how well it works. You still have to do a minor manual bleed afterwards, but for changing out brake fluid it exponentially speeds up the process!

Everything included fits exactly correctly. The choice in materials makes cleanup so much easier than "value" products that won't come off of the type of plastic used. If you are even slightly careful when using this, there's no chance you'll drip oil around.There are loads of places they could make small adjustments that would improve this product - but it's already priced around HALF of what you typically have to pay for something that's simply built right, so there's no complaint from me.

Works good for small jobs, very strait forward.
