Four-port, stainless steel barstock, point-of-use regulator for high purity gases
3272031-01-M1L shown
Four-port, stainless steel barstock, point-of-use regulator for high purity gases

The 327 Series regulator provides secondary pressure control of non-corrosive, liquified, or high purity (up to grade 5.5) gases. Unlike most pipeline equipment, the regulator is rated to full cylinder pressure, making it ideal for point-of-use pressure control in high purity gas distribution systems. While the 327 Series regulator may be used with mildly reactive gases, it is not for use with toxic or highly corrosive gases.
