Nti 83223-1 Pressure Switch 1/4 Inches Npt TI100-200 Replacement 83218

Product Description

The NTI 83223-1 is a replacement pressure switch designed for use with NTI TI100-200 boilers manufactured under ASME standards after June 2007. Pressure switches are critical safety and control components in hydronic heating systems. They monitor system pressure and send a signal to the control board when pressure falls outside the normal operating range. This protects the boiler from running under unsafe conditions and helps prevent damage to heat exchangers, pumps, and other key components.

NTI boilers are high-efficiency condensing units used in residential and light commercial heating applications. The TI100-200 series is a popular line among HVAC technicians and plumbing professionals who need reliable, long-lasting performance. When the original pressure switch fails, the boiler may lock out, display a fault code, or fail to fire. Replacing the switch with the correct OEM part restores normal operation quickly and safely.

This pressure switch features a 1/4 inch NPT connection, which is a standard pipe thread size found across a wide range of HVAC and hydronic heating equipment. The NPT fitting allows for a secure, leak-free connection to the pressure port on the boiler. Installation is straightforward for qualified technicians familiar with NTI boiler service procedures.

Using the correct replacement part number is essential for ASME-rated units built after June 2007. This part replaces reference number 83218 and is sold individually. Whether you are performing a routine service call or troubleshooting a pressure fault, the NTI 83223-1 is the right part to have on hand for TI100-200 boiler repairs.
