The compact, proven design is reliable and highly efficient at removing air from hydronic heating and cooling systems. The protective cap includes expansion sealer rings ensuring that the Flexvent will not leak. There is a substantial distance between the water and the closing mechanism, reducing the chance of contamination. Most Flexvent options are equipped with a shut-off valve for easy installation and dismantling. The air escape tube can be opened or closed with an adjustment screw.
