Honeywell 4074BTN Bag Assembly

For contractors servicing high-voltage ignition systems, the Honeywell 4074BTN Bag Assembly provides the essential hardware required for secure electrical terminations and mechanical stability. This replacement bag assembly is specifically engineered for use with the Q624 Series, including the Q624A solid-state ignition transformer. Precision-machined to original equipment manufacturer (OEM) standards, it ensures the integrity of the secondary voltage circuit and prevents arcing or loose connections in demanding burner environments.

The Honeywell 4074BTN—which is technically identical to the 4074BTN/U—is a 3-piece kit designed to maintain the electrical path between the transformer and the ignition electrode. This assembly facilitates a reliable HVAC part installation by providing a high-quality terminal connection kit that withstands high-temperature cycles. Whether you are performing routine maintenance or a critical repair, using these verified components prevents moisture ingress and vibration-induced failures common in industrial heating applications.

• Universal Compatibility: Fully compatible with the entire Honeywell Q624 Series and Q624A ignition transformers.
• Complete Hardware Kit: Includes the 103218 washer, 135793 cap terminal, and 37356 ferrule for a comprehensive fix.
• Industrial Build Quality: High-grade materials resist corrosion and thermal stress, ensuring long-term conduction.
• Seamless Integration: Designed for an exact fit to eliminate the need for field modifications during transformer hardware replacement.

Common Questions & Contractor Insights

Is the 4074BTN interchangeable with the 4074BTN/U?
Yes, these are the same professional-grade assembly. The "/U" suffix simply denotes a universal-packaged part; the internal components and specifications remain identical.

Which specific components are included in this bag assembly?
The kit contains one 103218 washer, one 135793 cap terminal, and one 37356 ferrule, providing all the specialized pieces needed for a single Q624 termination.

Can this be used on competing solid-state transformers?
This hardware is specifically tapped and sized for the Honeywell Q624 series. For non-Honeywell equipment, we recommend verifying terminal thread pitch and ferrule diameter before installation.
