Triangle Tube boilers are common in high-efficiency hydronic systems, and replacement parts need an exact model match to fit and function correctly. Even within the same product family, parts like ignitors, sensors, gaskets, and control components can vary by input size and revision—so the safest starting point is always the model number.
SupplyHouse carries Triangle Tube replacement parts for supported models, including ignition components, sensors, gaskets, and service kits. If you already know your boiler line, you can also browse parts by product family (like Prestige Solo).
Note: Triangle Tube brand has been discontinued by the manufacturer as of 11/3/2025, and that replacement parts will continue to be available as supplies last.
Enter the model number exactly as printed on the manufacturer label. Matching the complete model number is the quickest way to avoid ordering the wrong ignitor, gasket, sensor, or control.
Go to the unit that needs the replacement part and locate the manufacturer nameplate or label. For Triangle Tube units, the label is typically located on the outside of the unit. Take a clear photo of the full label so you capture the complete model number in one shot.
If the model number isn't available, category browsing can still help narrow the list before confirming fit by model:
