Venom® Leak Detector
Let Nothing Escape.
When it comes to gas systems, accuracy matters. Venom® Leak Detector delivers fast, visual confirmation of leaks — so nothing escapes your attention and nothing is left to chance.
Designed for ease of use and precise application, Venom makes it simple to identify leaks exactly where they occur, helping you fix problems quickly and confidently.
Precision You Can See
Venom Leak Detector creates high‑visibility bubbles at the source of a leak, allowing you to instantly pinpoint problem areas without guessing, listening, or using electronic tools. The bright green/yellow formula stands out clearly in low‑light or busy work areas, making even small leaks easy to spot at a glance.
Unlike household soap solutions, Venom is engineered specifically for leak detection — delivering consistent, reliable results every time you spray.
Compact Size. Controlled Spray. Confident Results.
Venom Leak Detector pairs a convenient 8 oz size with a precision spray applicator, giving you better control and less waste than oversized aerosol cans — and more accuracy than traditional dauber bottles.
The compact bottle is easy to handle, easy to store, and ideal for reaching fittings, joints, valves, and tight spaces where leaks commonly occur. You get targeted coverage exactly where you need it — no mess, no excess spray, no guesswork.

Testimonials
"The lug nuts on my refuse truck were seized. I had to work very hard to remove the front wheel, applying a lot of heat with a torch. I sprayed the five remaining wheel ends with Free All and got them off with no issues, and without needing the torch. It was an awesome help!"
"I was working on a new-to-me bait trailer and had to adjust the rollers to fit my boat. Every u-bolt was rusty and just wanted to break. I wasn't able to find new u-bolts the same size and the local implement dealer sales reps mentioned Free All. WOW is all I have to say. Nothing I have found works like this."
"Free All is truly amazing! I recently picked up a vintage Herter's Husky snowmobile that had a frozen motor after sitting for over 30 years. I removed the spark plugs, gave both cylinders a shot of Free All and let it soak in for about 10 minutes. I applied little pressure to the crank with a ratchet. The motor cracked loose and spun free. Not only did it free the motor up, but I was able to get it running about 10 minutes later. Thank you for making such a wonderful product!"
"My buddy went to a car show in California and picked up a sample can of Free-All. Since I do all the work on his vehicles, he gave it to me. I’ve used about half the can installing a lift kit on a rusted truck and working on some other projects. It works every time! The diesels I work with have bolts that always seem to seize in the block and break, no matter what I soak them in. Free-All is the only product I’ve found that works flawlessly. I am a customer for life!"
"I needed to swap an engine in my 4WD pickup truck and did so using an engine from a front wheel drive car. I had to use the exhaust manifolds from the old engine, so needed to remove those from the replacement. The initial effort to break the bolts loose failed, and I feared I would break them off in the block. I doused the area on and around each bolt with Free-All and tried again a couple of days later. The bolts turned right out without binding. Free-All worked far better than the other penetrants I'd previously used."
"I love Free All! I had a pair of rusted cutters that wouldn't even pry apart with WD-40. I sprayed a little Free All on them and was able to open them with one hand. This is the best stuff ever!
