Allanson Transformers 29-276 Spring

The Allanson Transformers 29-276 Compression Cone Spring is a precision-engineered HVAC ignition component designed to ensure consistent electrical contact in high-voltage burner systems. Specifically built for oil burner ignition transformers, this conical compression spring provides a reliable bridge between the transformer terminal and the electrodes. Its unique tapered shape offers superior stability compared to standard springs, effectively preventing buckling or lateral shifting during operation. This ensures a steady spark for furnace ignition systems, which is critical for maintaining high combustion efficiency and preventing startup delays in residential or commercial heating units.

By utilizing a 29-276 Allanson spring, technicians benefit from a part that allows for a reduced solid height and increased travel, making it an ideal choice for compact transformer housings where space is limited. Whether you are performing a routine burner maintenance task or a complete HVAC system repair, using authentic Allanson replacement parts guarantees compatibility with leading burner manufacturers such as Conroy and Grimsby. This spring is a vital ignition transformer accessory for anyone seeking to restore dependable heating performance.

• Enhanced Contact Stability: The tapered cone design provides a secure "foot" to prevent spring buckling, ensuring a constant electrical path.
• High-Temperature Durability: Engineered to withstand the intense thermal environment of an oil burner housing without losing its tension.
• Space-Efficient Design: The conical helix allows coils to nest when compressed, offering a lower solid height for easier installation in tight terminals.
• Universal Compatibility: Frequently used in ferromagnetic ignition transformers across multiple HVAC brands for reliable spark delivery.

• Why use a cone spring instead of a straight spring? A compression cone spring provides better stability and prevents the spring from bending sideways when compressed, which is vital for maintaining high-voltage contact.
• Is this spring compatible with gas burners? While primarily used in oil application transformers, compatibility depends on the specific terminal type of your ignition module.
• Does this part come in a pair? Typically, these transformer springs are sold individually, though many ignition systems require two for double-pole configurations.
