Honeywell 393690-13 Flange Kit

The Honeywell 393690-13 Flange Kit is a critical service component designed for high-pressure gas valve applications. This 1/2" elbow flange assembly provides a secure, leak-proof interface between the manifold and the gas control valve, ensuring system integrity in residential and commercial heating environments. Engineered as a direct replacement flange, the kit includes a precision-molded O-ring, 9/64" hex screws, and a dedicated hex wrench for immediate field installation. This HVAC gas valve flange is identical to the 393690-13/U model, maintaining strict adherence to OEM tolerances for gas flow efficiency and vibration resistance. For technicians managing Honeywell valve maintenance, this bag assembly simplifies the sealing process by providing all necessary hardware to prevent bypass leakage. Its robust construction facilitates a reliable gas line connection, minimizing pressure drops across the valve body and supporting long-term operational stability in demanding thermal cycles.

• Complete Field Kit: Includes the 9/64" hex wrench and matching screws to eliminate tool-sourcing delays during service calls.
• High-Integrity Sealing: Features a high-grade replacement O-ring to ensure a gas-tight seal and prevent methane leaks.
• OEM Standards: Manufactured to the exact specifications of the 393690-13/U for consistent fitment and pressure ratings.

Common Questions

Is the 393690-13 interchangeable with the 393690-13/U variant?
Yes, both parts are technically identical. The "U" suffix typically denotes retail packaging, but the physical elbow, hardware, and port dimensions remain exactly the same for industrial and residential applications.

Does this kit include the gasket or only the O-ring?
This specific bag assembly utilizes a high-performance O-ring designed to seat within the machined groove of the elbow flange, providing a superior seal compared to flat gaskets in high-vibration gas train environments.

What is the thread size for the gas pipe connection?
The flange features a standard 1/2 inch NPT female thread, making it compatible with most standard residential and light commercial gas manifold piping.
