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.

Great team of professionals and they know the valve business. I purchase all my valves from Crume now and would recommend them to anyone.
John Pickett, Driller, Blue Water Drilling
Had a pressure regulator blow at 6am on a Saturday morning. By 10am Crume solved the problem. Can’t beat the service.
Ed, Site Manager, Desert Rat Gas Co.
On extremely short notice, Crume built custom sight glass and gauge cock assemblies that were 12 feet in length. Fit perfectly the first time and ahead of schedule.
