The NTI 65111933 is a 2-position electrical connector used in hydronic heating and boiler control applications. This connector provides a secure, low-profile termination point for wiring harnesses and control circuit connections within NTI boiler systems. Licensed HVAC technicians and hydronic heating installers rely on connectors like this to maintain clean, reliable electrical interfaces during service calls, board replacements, and system commissioning. Getting the exact OEM connector ensures a proper fit and retention to the mating receptacle without improvised workarounds.
This connector is suited for residential and light commercial hydronic heating systems where NTI boiler equipment is installed. It is commonly needed during control board service, wiring harness repair, or any situation where the original connector has been damaged or lost. Using the correct 2-position connector preserves the integrity of the original wiring scheme and simplifies reinstallation.
Designed as an OEM-style replacement connector for NTI boiler control and wiring harness applications. No specific model compatibility data was provided in the product input.
Installation should be performed by a licensed HVAC technician or qualified hydronic heating professional. Always shut down and de-energize the boiler system before disconnecting or reconnecting any electrical connectors. Verify that conductor gauges and termination types are appropriate for the connector before reassembly. Follow local electrical codes and the equipment manufacturer's service documentation throughout the repair.
