Honeywell 305965 Indicating Gauge

The Honeywell 305965 Indicating Gauge is a professional-grade pneumatic receiver gauge engineered for high-precision monitoring in commercial HVACR and industrial automation systems. Featuring a compact 1-1/2 inch diameter face, this instrument provides clear, immediate pressure readings across a 0-30 PSI range. Designed for reliability in dense control panels, it utilizes a 1/8 inch NPT center back connection (center stem back mount) for a secure, low-profile installation. This unit is the direct manufacturer replacement for the 305965/U, ensuring full compatibility with existing pneumatic control systems and residential or industrial boiler setups. As a veteran-preferred pressure indicating gauge, it offers the durability required for chemical plants, refineries, and manufacturing facilities where accurate fluid or gas pressure measurement is critical to system safety and performance. Its stainless steel construction options and calibrated movement deliver consistent accuracy for contractors managing complex hydronic and air-handling sequences.

• Optimized Form Factor: The 1.5-inch dial allows for high-density mounting in standard pneumatic control cabinets.
• Universal Connectivity: Standard 1/8" NPT center back mount ensures seamless integration with most Honeywell pressure controls.
• High-Visibility Scale: The 0-30 PSI face is specifically calibrated for standard pneumatic signal ranges and low-pressure steam applications.
• Proven Reliability: Engineered to withstand the vibrations and environmental demands of active mechanical rooms.

Is the Honeywell 305965 compatible with the 305965/U model?
Yes, the 305965 and 305965/U are functionally identical and can be used interchangeably in all HVACR applications.

What is the primary mounting style for this gauge?
This is a center back stem-mount unit, designed to thread directly into a female 1/8" NPT port on a receiver or manifold.

Can this gauge be used for both liquid and gas pressure?
This indicating gauge is primarily utilized for air in pneumatic systems and non-corrosive fluids compatible with its internal brass and steel components.
