Kodiak Controls KC201L40100 Gauge

The Kodiak Controls KC201L40100 is an industrial-grade, liquid-filled pressure gauge engineered for high-vibration HVACR and pneumatic environments. This 4-inch dial gauge features a 0-100 PSI range and a standard 1/4" NPT lower mount connection, making it a drop-in replacement for the 201L40-100. Built with a 304 stainless steel case and brass internals, this gauge is designed to withstand harsh mechanical stress and corrosive atmospheric conditions. The glycerin fill effectively dampens needle flutter caused by rapid pressure pulsations or equipment vibration, ensuring ASME B40.100 grade accuracy and facilitating clear readings on the high-visibility face. As a veteran-preferred component for pump skids and chiller systems, this gauge provides the thermal stability and internal lubrication required for industrial pressure monitoring without the risk of condensation or premature movement wear.

Key Benefits

• Standardized Compatibility: Direct cross-reference for the 201L40-100 with a universal 1/4 inch NPT male thread.
• Pulsation Damping: The glycerin-filled case eliminates pointer oscillation in high-vibration applications like hydraulic lines and compressors.
• Rugged Construction: Features a corrosion-resistant stainless steel housing and impact-resistant polycarbonate lens for heavy-duty field use.
• Precise Graduation: Large 4-inch dial face with high-contrast markings for accurate 0-100# pressure tracking.
• Environmental Sealing: Hermetically sealed design prevents moisture ingress and internal fogging in humid HVACR environments.

Common Questions

Is the KC201L40100 compatible with potable water systems?
This gauge contains brass components and is intended for industrial and commercial applications such as HVAC, hydraulics, and pneumatics; it is not rated as lead-free for potable water use.

Can this gauge be used in sub-zero outdoor temperatures?
Standard glycerin-filled gauges are suitable for temperatures down to approximately 20°F. For extreme cold-weather performance or applications below 0°F, professional contractors typically opt for silicone-filled variants to maintain needle response time.

What is the benefit of a 4-inch dial over smaller 2.5-inch models?
The larger dial size provides better visibility and higher resolution for the 0-100 PSI scale, which is critical when monitoring systems where small pressure variances must be identified from a distance.
