The Jerguson Series 20 Glass Gage is the most common gage produced and will cover 80-85% of the applications encountered. Important features include a recessed gasket surface (standard on all gage series) and shrouded covers.  A recessed gasket surface provides positive location of the seal gasket during both assembly and field repair and also makes it possible to repair a Jerguson glass liquid level gage while it is mounted to the vessel.  The recessed gasket surface is also an important safety feature in the fact that it contains the gasket and helps prevent lateral movement which could lead to a gasket blow-out (as with competitive gages.)

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).  For temperature above 600°F (316°C) aluminosilicate glass must be used.
