Durable and effective
The kit has held up while plugging a large EGR valve. Much more durable than our Harbor Freight one

Amazing customer support
I'm not a professional mechanic, I just have a turbo project car that I smoke test to check for leaks from time to time. I like this product but did experience failure of the cap that holds the rubber bladder in. I went to their website and sent them a quick email describing what happened and they were very quick to email me back and got a replacement in the mail very fast. I was very impressed with how nice they are and how fast they were to help me.

Easy to use
I’ve used the Autoline smoke test bladder on multiple EVAP and intake systems, and it’s been rock solid. The rubber is thick and pliable, and it inflates evenly to make a tight, reliable seal every time — whether you’re working on throttle bodies, intake boots, or tailpipes.It pairs great with any smoke machine setup. I’ve had no issues with leaks or blowouts, even when slightly overinflated for stubborn connections. The inflation valve is smooth, doesn’t stick, and the bladder collapses fully for easy storage.What I really appreciate is the durability — I’ve used it on hot components and rough surfaces, and it’s held up with no tears or weak spots. If you’re doing intake smoke testing, EVAP work, or chasing vacuum leaks, this is a must-have.Way better than trying to rig something up with rags or tape — this is professional-grade and saves serious time.

Thin material
The bladder material is thin so it worries me that it will puncture easily. The product works great as described though. Longevity is the only area I question with this tool.
