Review: I tried the rest then tried the best! - For many months I've had problems with air collecting in the bathroom radiator and tried auto air vents (Aladdin) without success. However, I fitted this product to the radiator yesterday and woke up this morning to a radiator as hot as all the others and no air present. It may be a tad more expensive then the other radiator vents available on the market but false economy if you go for the cheapest like I did and it doesn't work. This was well worth the money! Review: Actually works - Have tried a few different types and this one actually works perfectly ## Features - Automatic bleed valve with very compact, white painted brass housing and 1/2 inch male thread. - The white 1/2 inch Flamco Flexvent H bleed valve is suitable for domestic installations with a glycol content of up to 50%. - The extremely compact Flamco White Flexvent H bleed valve can be easily installed in systems that work at a temperature below 90 °C (peak values up to 120 °C are tolerated) and at a maximum pressure of 6 bar (peak values up to 10 bar are tolerated) - The Flamco Flexvent H air intake is available in white to match the colour of modern radiators, and with a 90" angle to fit directly into the radiator door. - The Flexvent seal seat is protected from dirt as the protective chamber is placed on the float.
