This gasket seals the burner door assembly on the front of the boiler combustion chamber. A proper seal at the burner door is critical for safe and efficient boiler operation. When this gasket wears out, cracks, or hardens, it can allow combustion gases to escape the firebox. This creates a safety hazard and reduces heating efficiency. Replacing a failed gasket restores the tight seal needed for correct combustion and venting. HVAC technicians and boiler service professionals rely on OEM-spec replacement gaskets like this one to return equipment to factory-rated performance. The NTI TX series is a line of high-efficiency gas-fired hot water boilers used in residential and light commercial hydronic heating systems. These boilers are known for their compact design and high thermal efficiency ratings. The burner door gasket on TX series units must withstand repeated heating and cooling cycles while maintaining a gas-tight seal. Using the correct OEM replacement part ensures proper fit and long service life. A mismatched or aftermarket gasket may not seat correctly against the boiler body and door, leading to leaks and failed inspections. This part is sold individually as a single unit. It is stocked as a nonstock item with a standard lead time, so ordering in advance of scheduled maintenance is recommended. Boiler service technicians should verify the model number of the NTI TX unit on site before ordering to confirm fitment. This gasket is an essential consumable in any planned maintenance program for NTI TX series hydronic boilers.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOEM replacement burner door gasket for NTI TX series boilers\u003c\/li\u003e\n\u003cli\u003eSeals the combustion chamber door to prevent flue gas leakage\u003c\/li\u003e\n\u003cli\u003eSold as a single unit, designed for direct OEM fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe NTI 84737 burner door gasket is a direct OEM replacement for TX series boilers, providing a reliable combustion chamber seal that supports safe and efficient boiler operation during routine service and maintenance.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NTI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84737\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Replacement Part\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Series\u003c\/strong\u003e: NTI TX Models\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Size\u003c\/strong\u003e: 1 each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlternate Part Number\u003c\/strong\u003e: 6000084737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NTI","offers":[{"title":"Default Title","offer_id":51120845619506,"sku":"84737","price":44.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00007831.png?v=1777741226","url":"https:\/\/voomisupply.com\/products\/nti-84737-burner-door-gasket-tx-models-replacement-part","provider":"Voomi Supply","version":"1.0","type":"link"}
