Four-Port, Stainless Steel Barstock, Point-of-Use Regulator for High Purity Gases

The CONCOA 327 Series regulator delivers secondary pressure control for non-corrosive, liquefied, or high purity gases (up to grade 5.5). Rated for full cylinder pressure, it is well-suited for point-of-use control in high purity gas distribution systems. While it can handle mildly reactive gases, it is not recommended for toxic or highly corrosive gases.
