Why Jerguson
Armored Construction
Heavy-duty armored body protects the glass from process upsets and mechanical damage. Available in carbon steel, stainless steel, and alloy materials for virtually any process fluid.
ASME Code Rated
All Jerguson gages are designed and manufactured to ASME B31.1 and B31.3 piping codes. Boiler models comply with ASME Boiler and Pressure Vessel Code Section I.
Extreme Pressure & Temperature
High-pressure series rated to 6,000 psi and 750°F. The Series 51 handles up to 10,000 psi for the most demanding hydraulic and process applications.
Non-Intrusive Magnetic Option
The Magnicator II provides reliable level indication with no glass and no process contact — the right choice for corrosive, toxic, or ultra-high-purity fluids.

What are your service conditions?
Level Gages
Armored, reflex, transparent, magnetic, and tubular models covering standard through extreme-pressure service.
Armored Level Gages — All Series
Complete line of Jerguson armored transparent and reflex level gages. Series 300L, L10, 20, 32, 40, and 51 covering standard through high-pressure service.
Reflex Level Gages
High-contrast reflex gages for clear single-phase liquid level indication. Prism glass reflects vapor space as bright silver and liquid as dark — no illuminator required.
High Pressure Level Gages
Armored level gages rated to 6000 psi for demanding high-pressure process and hydraulic applications. Series 32, 40, and 51.
Magnicator II Magnetic Level Gage
Non-intrusive magnetic level indication with no glass and no process contact. Ideal for corrosive, toxic, or high-purity fluids where direct visual access is not acceptable.
Tubular Gage Assemblies
Simple, economical tubular glass level gages for low-pressure, non-hazardous liquid level applications.
Valves, Accessories & Tools
Isolation valves, weldpads, LED illuminators, and engineering tools for complete gage installations.
Isolation Valves
Jerguson isolation valves for level gage installations. Gauge cocks, block valves, and drain valves matched to gage pressure and temperature ratings.
Weldpads
Weldpad connections for direct vessel mounting of Jerguson level gages. Available in carbon steel and stainless steel.
LumaStar™ EPL-100 LED Illuminator
LED illuminator for transparent level gages. Improves visibility of liquid level and interface in low-light or outdoor installations.
