Honeywell 37356-520 Rajah Connector

The Honeywell 37356-520 Rajah Connector (also identified as 37356/520/U or 37356 SSN) is a high-specification industrial terminal designed specifically for critical ignition electrode connections. As a veteran-grade HVAC replacement part, this connector provides the mechanical stability and low-resistance signal path necessary for high-voltage ignition sequences. Field-proven for its durability, this Rajah-style terminal is engineered to withstand the thermal stress and vibrational fatigue common in heavy-duty burner assemblies, ensuring consistent spark delivery without voltage leakage or terminal degradation.

This OEM-equivalent connector is the primary solution for Honeywell pilot burner maintenance, offering direct compatibility with Q179 series ignition electrodes. Whether you are servicing a Q179A, Q179B, Q179C, or Q179D, the 37356-520 establishes a secure, locking fit that prevents nuisance flame-outs caused by loose or corroded electrical junctions. Its robust insulation and corrosion-resistant construction make it an essential stock item for technicians managing commercial boiler systems and industrial heating applications where downtime is not an option.

• Compatible with Honeywell Q179A, Q179B, Q179C, and Q179D electrode series.
• Ensures high-integrity electrical contact for consistent ignition spark.
• Heavy-duty SSN construction designed for elevated temperature environments.
• Direct replacement for 37356/520/U and 37356 SSN part numbers.

Is the Honeywell 37356-520 compatible with all Q179 electrodes?
Yes, this Rajah connector is specifically engineered for the Q179A, Q179B, Q179C, and Q179D series, ensuring a precise mechanical fit.

What is the difference between the 37356-520 and the 37356/520/U?
These are identical parts with different nomenclature; both offer the same technical specifications and 100% interchangeability.

Can this connector be used in high-vibration burner environments?
The Rajah-style locking mechanism is specifically chosen for industrial applications to maintain connectivity despite vibration and thermal expansion.
