Carbyne Suction Gun, See-Through, Heavy Duty Professional Quality • from a Family-Run Tool Company Based in The U.S.A.

Great tool. Had air leaks at the clear tube threads and could not pull a full tube of oil. Put a couple wraps of teflon tape and now things are sealed as they should be and I can pull a full tube of oil. Bought it solely because of the clear tube and having the ability to see the oil being pulled out.

nice looking pump but rubber seal is very poor qualityoil flows past the plunger to the back sideleaks all over the place, makes a big mess when you use it

Nice, high quality item that works well. Clear body is a plus! Easy to pull a sample of fluid and see condition right away, without having to move fluid to a separate container. I used it for adding new fluid to my vehicle manual transmission and differential. Seals work well and no leaks. Strong enough to pull cold 75W-140 gear oil with ease. Overall a nice tool at a nice price 👍

Works fine enough, beats a sharp stick to the eye but I wouldn't recommend using it without at least putting some thread sealing tape around the threads on either end... otherwise it may not get good suction and may leak.

The joints where the red aluminum caps meet the clear plastic tube both leaked badly, so each time I'd try to fill the cylinder I'd have about 50-75% air depending on how viscous the fluid was.The solution was to unscrew the aluminum caps from the plastic tube, clean and degrease the threads, then put epoxy all over the threads before reassembling. It works perfectly now, but I took off three stars because it was nearly useless out of the box.

This is just what i like. A heavy Duty WELL made tool. Haven’t used it yet . Need to find a longer tube and a bag to keep it in. But Very Impressed with the. Quality. . 👍🦋I will see if it leaks. That should be an easy fix with a better washer. Round instead of flat.

Product works great for filling hard to reach parts like transfer case and differential. Doesnt work well to remove fluid from anything in my opinion. Tried sucking fluid from the bottle and its just didnt work. Had to open the cap and pour fluid in than close it and fill my differential.

This would be a awesome product if they put more attention to building process. The one i received was leaking where the plastic see through meets the machined top piece where the plastic meets.(seems to be threaded on) did not bother to try to unscrew and apply Teflon tape, or maybe should redesign and should be pressed on with some sort of seal. will be ordering the full solid suction gun(non see through)
