Excellent quality and very grippy
I was pleasantly surprised by the quality of these, purchased them to isolate my F&E tank so I could replace a seized 3 port valve without having to drain my hot water cylinder down, worked a treat and held while I did the job, these will last for years and would stand up to frequent professional use

Fit for Purpose
They fit. They did the job. They look like they will last. Very pleased I bought them. You only need them to work once and you will smile like a Cheshire cat.

Work Well - Unless Pipes are Burred
In some ways not an issue for the product but something to be aware of - if the pipes have any burrs, the bungs will be cut up quickly and will, I'm sure, become unusable.Using pipe slices - burs are always internal, so using the external cap worked a treat and was far more secure than the internal bung option.Still I liked these and recommend them to stop the flood when a stop cock/gate valve doesn't stop the flow. I felt confident leaving them in place overnight to do their job.

Handy tools
I used these last summer to clean my system radiators and cold waster tank. Very useful to prevent leaks and bung pipes.

Limitations on use
I purchased to help me change some rad valves without draining down. I have a central heating system with a make up tank in the loft. (It is not a pressurised type system) On my system the make up pipe from the tank happens to be in 22mm. So the inside part of the brass tank connector in the make-up tank is slightly bigger bore than the inside of a 22mm pipe itself. Many systems will be like this. The largest 22mm part of the bung is not big enough to seal a 22mm tank connector. I ended up winding some elec insulating tape around the 22mm end of the bung to make it slightly bigger. I might as well have made something up from scratch rather than pay £13 quid. I assumed that the taper of the 22mm bung would be big enough to cater for a 22mm tank connector. I thought wrong. It’s a shame because the silicone is great and better than hard rubber.
