Did it's job though no leaks detected. Good practice to quality check your work. It will save you money.

Works fine, will last a long time.

I got this for gas leaks on furnaces. The swab in the bottle is great. Not using a spray here works out best. It lost a star because the bottle leaks. The cap doesn't seal right. I have a spot in the truck to keep it upright. Aaac Service heating and air furnace repair in McDonough recommends this product.

Smelled gas from the stove and had a technician come assess; he used something similar to this product and I didn’t fully trust his assessment as I swear I thought I saw some bubbling! So after he left, I Bought this item to do my own testing! It arrived quickly and gave me the reassurance I needed that my stove did not have a gas leak! Quick tip for using: The item comes with an applicator; I noticed that the liquid has some bubbles just from shipping so I let it sit for a bit before I applied it, as when I first applied it the natural bubbles from shipping made me believe there was a leak- just a heads up! (FYI the way I pushed some of the small bubbles out quicker was by gently banging the bottom of the item on the counter a few times!) enjoy!

This stuff works really good for finding small leaks in flare connections on hvac equipment

Bubbly Wubbly

Bubbles find leaks very well .

I found a very slow leak at a Schrader valve using this. The bubbles are durable and thick so unlike soapy water they don't dry out and pop before they have a chance to work on a small leak. In this case I put a small hole in a valve cap, twisted the cap on the suspect valves and applied the bubble solution to the hole. It took about 30 seconds to see bubbles appear where my normal bottle of soapy water showed nothing. Amazing stuff!

Excelente! pequeñas fugas pueden ser detectadas, la burbuja es resistente. Lo recomiendo 100%!

works well

I purchased these bubbles based on videos that I saw on YouTube that recommended them for testing leaks on a mini split lineset. Got my AC recharged last summer and it was out of refrigerant within 8 months. I pressurized the system with Nitrogen, then testing all four connections. I used the enclosed cotton dabber to apply the bubbles to the connections. Within a few seconds, i found the leak. The bubbles stay on the fitting for at least 30 mins. I also used the bubbles on a tire valve stem and found a slow leak that was causing my tire to go flat.

Good stuff Good for gas leak
