About this heater

The Allied Innovations Heater Terminal Nut (000625) is a precision-engineered stainless steel connection component designed for spa heater assemblies. This 10-32 Keps nut provides secure electrical termination in hot tub heating systems, ensuring reliable power delivery and preventing corrosion in demanding spa environments. The stainless steel construction resists rust and mineral buildup while maintaining optimal conductivity.

At Bubbles Supply, we guarantee this OEM terminal nut delivers an exact fit for your Allied Innovations heater assembly. Every genuine part ships same-day from our Canadian facility and includes our comprehensive 1-year warranty for complete peace of mind. This critical connection component helps restore proper heater function when original hardware fails or shows signs of corrosion. Always disconnect power and allow heater to cool completely before installation, and ensure proper torque specifications to maintain safe electrical connections.

Before you buy — quick checklist

  • Confirm your heater assembly uses a 10-32 thread terminal stud before ordering
  • Inspect the terminal stud for damage — a stripped or corroded stud will need replacement too, not just the nut
  • Verify the heater brand is Allied Innovations; terminal thread sizes vary by manufacturer
  • Check for signs of arcing or melting around the existing nut — if present, inspect the full terminal and wiring harness before reassembly

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
