This is an OE product. Excellent quality
This is a Zilmet unit, exactly the same that Vaillant fit into their boilers.Mine failed and actually started leaking water and it left us without heating or hot water.Called a couple of local plumbers merchants who wanted an obscene amount of money for one of these.Amazon to the rescue, and it came from Unvented Components who I have used before.This fitted in literally five minutes and the boiler is back up and working again.The expansion vessels have a life or around 10 years, so check your serial number of your boiler to see when it was installed before it fails on you. The second two digits are the year your boiler was made.It caused the F.75 error on the boiler and in my case I had to replace the pressure sensor as well.

Fixed the issue, but fibre washer is brittle
The expansion vessel works great, still have to access the long term. I would not recommend to use the provided fibre washer, it's really fragile compared to the original one, it cracked under little torque and caused a leak, after replacing to a new one, no issues!

Genuine part
This was made by the same people who made the original one for the boiler as it had the same label. Great value for money and I was able to fit it myself as there was no need to go near the gas or electrical parts of the boiler other than to turn it off!
