This heavy-duty component is designed to provide a secure, airtight interface between the burner housing and the combustion chamber, preventing dangerous fuel leaks and pressure loss. With dimensions typically measuring \u003cstrong\u003e4-1\/4\" ID x 7-3\/8\" OD\u003c\/strong\u003e, this \u003cstrong\u003eWayne Combustion Replacement Part\u003c\/strong\u003e is the standard for technicians servicing \u003cstrong\u003eWayne MSR, MH, EHA, EH, and EHASR\u003c\/strong\u003e series burners.\u003c\/p\u003e\n\u003cp\u003eConstructed from high-temperature resistant material, the \u003cstrong\u003eWayne 12484 Gasket\u003c\/strong\u003e withstands the intense thermal cycling common in industrial and residential pressure wash heaters and furnaces. Its \u003cstrong\u003eflange-standard large\u003c\/strong\u003e profile ensures maximum surface contact, effectively compensating for minor irregularities in the mounting surface to eliminate bypass air that can degrade combustion efficiency. When replacing burner motors or performing a tune-up, installing a fresh \u003cstrong\u003e12484 burner gasket\u003c\/strong\u003e is standard protocol to maintain system vacuum and optimize the fuel-to-air ratio for clean, stable ignition.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpecifically designed for \u003cstrong\u003eWayne Combustion\u003c\/strong\u003e MSR, EH, MH, and EHASR burner series.\u003c\/li\u003e\n\u003cli\u003eEnsures a precise, high-temperature seal to prevent exhaust leakage and maintain system efficiency.\u003c\/li\u003e\n\u003cli\u003eStandard \u003cstrong\u003elarge flange\u003c\/strong\u003e dimensions (4-1\/4\" ID) fit most high-capacity burner housings.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty material construction resists degradation from fuel oil and combustion byproducts.\u003c\/li\u003e\n\u003cli\u003eCritical for maintaining proper draft and air settings during HVAC system commissioning.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat burner models are compatible with the Wayne Combustion 12484?\u003c\/strong\u003e\u003cbr\u003eThis gasket is the standard large flange seal for Wayne MSR, MH, EHA, EH, and EHASR series burners often found in pressure washers and furnaces.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the physical dimensions of this flange gasket?\u003c\/strong\u003e\u003cbr\u003eThe unit features an Inner Diameter (ID) of approximately 4-1\/4\" and an Outer Diameter (OD) of 7-3\/8\".\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it necessary to replace the gasket every time the burner is removed?\u003c\/strong\u003e\u003cbr\u003eYes, veteran HVAC technicians recommend replacing the flange gasket during any service that involves unmounting the burner to prevent air leaks and ensure a proper seal.\u003c\/p\u003e\n\u003cp\u003eDisclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
