Brooks Instrument Sho-Rate GT 1350 65 mm Glass Metering Tube
About this part
R-2-65-5 is a borosilicate-glass metering-tube identifier documented for the legacy Brooks Instrument Sho-Rate GT 1350 variable-area flowmeter. The GT 1350 uses a 65 mm scale. Its calibrated air range depends on the installed float and scale configuration; Brooks documented glass, 316 stainless-steel, and Carboloy float configurations for this tube
Configurations vary. Verify the exact unit before choosing a replacement.

Documented R-2-65-5 Air Configurations
Brooks assigned a different model code and direct-reading range to each documented float. Normal-volume ranges apply at the document's stated reference conditions; the installed float and tube inscription must match before selecting a range.
| Float | Model code | Direct-reading range (normal L/h air) | Direct-reading range (SCFH air) |
|---|---|---|---|
| Glass | A1 | 0.4–4.2 | 0.01–0.16 |
| 316 stainless steel | A3 | 1.5–13.5 | 0.02–0.52 |
| Carboloy | A4 | 2–22 | 0.04–0.85 |
Compatibility and Service Boundary
R-2-65-5 is documented for the legacy GT 1350. Current 1350G literature instead lists R-2-65-A G through R-2-65-D G; it does not identify any of those tubes as a replacement for R-2-65-5. A substitution requires confirmation from Brooks using the complete meter model and serial number.
