### ⭐⭐⭐⭐⭐ My Karcher’s not leaking !
*by S***S on 29 December 2025*

It works. IT WORKS !

### ⭐⭐⭐⭐⭐ Perfect for Our B102
*by G***K on 23 September 2024*

We have an old Karcher B102, which still works, but the seal for the high pressure hose connection to the unit leaked. This kit had the perfect seal for the job.

### ⭐⭐⭐⭐ Good Quality, Fit Perfectly
*by B***P on 17 April 2017*

This review is for the Karcher 2640-729 O-Ring Set. A tad expensive for a few 'O' rings and a couple of jet nozzle thingies, but I couldn't be bothered with the hassle of waiting for the seals to go, then trying to go hunting about for the correct ones in town, then repeating all this when another one went! As it turned out on the day these arrived, I dragged the pressure washer out to attack the patio slabs and on checking the main seal connecting the wand hose to the washer, it has completely split! So timing was excellent and I am glad I ordered these. I suppose these should do you for a good few years of use. Knowing you've got some spares in case one splits, especially when you do have the welly to get the pressure washer out of storage and attack those jobs is handy. So 4 stars for delivery speed and quality, 1 mark deducted for the cost ( as there is extra postage on top if order is under £20).
