About this part
Brooks 1305D10A3A2A 6221-10C0A0A is an exact configured identifier for a Brooks Model 1305 glass-tube variable-area flowmeter. Brooks' official Model GT1305 manual identifies the Model 1305 as an O-ring-sealed flow indicator with standard female NPT connections and vertical inlet and outlet orientation. Exact-part inventory and auction evidence describe the observed configuration as having a 0-85 mm scale, 1-inch NPT connections, and a 6221 alarm assembly; those configuration details are preserved as observed evidence rather than generalized across every Model 1305
Configurations vary. Verify the exact unit before choosing a replacement.
