The Model BR300 series from Blue Ribbon Corporation is a high-quality dry or liquid-filled, all stainless steel back or bottom mount gauge for applications where brass may not be an option. 

The Blue Ribbon Series BR1000 diaphragm seal is an economical isolation device used to protect pressure instrumentation from the media to be measured. Designed with a rugged, two-piece bolted construction for pressure ranges from 30"Hg vacuum to 2500 PSI, the Series BR1000 provides exceptional protection in corrosive applications or where the pressure instrumentation process port alone may be prone to clogging.

Model BR400/BR800 Series from Blue Ribbon Corporation are a family of highly rugged stainless steel and brass process pressure gauges. They are designed to provide reliable process pressure measurements within safety critical environments such as oil and gas, chemical processing, power stations, environmental engineering and plant construction environments.
