The Series 300L gage is a lower cost gage with increased visible ranges.  The basic strategy was to provide more visible range per gage section at an economical price.  This gage series uses the proprietary Jerguson 25mm glass, which is thinner, narrower and longer than traditional gage glass.  The Series 300L features a recessed gasket surface, bar-stock non-shrouded covers and ASTM grade bolting.  Due to the length of each gage section this model is not recommended for high pressure steam service.
TEST PRESSURE: All gages are hydrostatically tested by Jerguson prior to shipment @ 1 -1/2 times the design pressure rating at 100°F (38°C).
