1 Gauge Adapters 22 Series ISO 900:2008 CERTIFIED General Information* The riser height or H dimension is measured from the outside of the tank shell to the face of the adapt er where the gauge attaches. This di men sion is shown for each adapter listed. Rochester forged-steel welding adapters are suitable for a minumum of 300 PSI [20,7 Bar] service and conform to ASME pres sure vessel code re quire ments, sec tions II and VIII. Met al lur gi cal cer ti fi - ca tions are avail able upon re quest. * Materials and specifications are subject to change with out notice. Pressure ratings sub ject to change due to tem per a ture and other en vi ron men tal considerations.
