The innovative Hygroseal™ technology (patent pending) with its long, leak-free life, provides a cost-effective solution to automatic radiator de-aeration. It also reduces corrosion, and system noise and provides a maintenance-free system - dispensing with the need for radiator keys. Their one–way valve makes them suitable for use with radiators that can cycle into negative pressure, typically loft conversion radiators or on the suction side of the pump. Our automatice bleed valves automatically release air trapped in your heating system.

Brilliant little product. I have an aluminium hall radiator (they don’t hold much water) that I had to bleed every week so was really annoying as only the bottom would heat up. Plenty of videos on YouTube for the not so keen DIY'er

This has sorted the problem straight away, can’t comment on reliability. Great product does what it was supposed to looks good and a very easy fit , just shut radiator valves at the bottom unscrew capping plug and screw this in and open up the radiator valves again I left the manual bleed valve in, in case there was any problems in the future. Pictures show the new valve and the old replaced bleed valve.

We have a double panneled designer radiator that always struggled to get the air out of it. I found them very easy to install, they have given me an even warmth over the radiators and that were good value for money. These are really easy to fit even for an amateur, simply shut thermostat to closed position if it has one and remove cover nut from other valve, then using Allen key close valve , then simply replace bleed valve , i was continually venting towel rails but now the system is running sweet.
