JERGUSON® SERIES 300L REFLEX AND TRANSPARENT LIQUID LEVEL GAGES

REFLEX AND TRANSPARENT GAGES FOR PRESSURES UP TO 300# ANSI

REFLEX MODEL: JER_R-300L_G
TRANSPARENT MODEL: JER_T-300L_G

The Jerguson® Series 20 liquid level gage is the most commonly specified gage and will cover 80-85% of all applications. Important features include a standard recessed gasket surface and shrouded covers. A recessed gasket surface provides positive location of the seal gasket during both assembly and field repair and makes it possible to repair a Jerguson® gage while mounted to the vessel. This design contains the gasket helping to prevent lateral movement which could lead to gasket blow-out (as with competitive gages). If you require shrouded covers, look at the Jerguson®series 20 reflex and transparent gages.
