Not only is K-Seal a number one bestseller in the UK and worldwide, it’s also the product professional motor technicians trust when dealing with a leak.
Testing has demonstrated that K-Seal sealed leaks in test conditions 100% of the time. That’s why so many professional motor mechanics refer to K-Seal as “the miracle in the little blue bottle.”
The good news is that, despite being the number one bestselling total coolant leak repair solution, K-Seal is still available at a modest price. Why pay more when you can have the best for less?
Don’t just take our word for it – here’s what a number of our happy customers have to say:
“I’ve used it myself and it works! And I wouldn’t recommend something I haven’t used.”
“Without a shadow of a doubt – because we’ve seen it work.”
“I had a Micro K Reg and I needed to use something for the radiator quickly. I found K-Seal, used it and it worked and to this day there have been no problems. That was about a year ago.”
“I used to use it when I was an AA patrolman, so I have experience of it and know it works.”
“K-Seal is the best stop leak I’ve used!
This product stops leaks like no other product that I have used. No time consuming flushing just add and go. I stopped leaks on an EGR cooler on my school bus It has been over a year and no leaks. This saved me over $1,000 dollars!”
Robert, Haugers Auto
“That worked. Thanks for all your help. You saved me $3000!”
Brian Campbell, USA
“I had seen all sorts of horror stories on the internet about ‘blocked oilways’ and ‘snake oil’ for similar products. I was motivated to buy this product because I had had excellent results with K-Seal.
I had a minor break to the head gasket of my 300Tdi Defender, consequently skimmed and repaired, but despite pressure testing I experienced occasional symptoms of the original problem. The independent Land Rover garage determined that there was a tiny fault in the head, they used K-Seal and it has been problem free ever since.”
Adrian Cherrett, UK
“2 1/2 years ago, I used K-Seal to stop a head gasket leak on a ’97 2.2L Sunfire motor, with 175K miles. Poured it in as directed, and the leak stopped within an hour. Nearly 2 years, and 25K miles later, it has remained relatively leak free!
There are many similar products on the market, but in my opinion, this is the best.”
“Your product is a miracle product. I had a leak in my water pump and I didn’t have money to repair my water pump. I bought k seal and it repaired it instantly. It was a life saver – thank you for creating this product.”
Christine Young, South Carolina
