Utica-Dunkirk 240010288 O Ring
Experienced technicians know that a call-back is usually the result of a failed seal. The Utica-Dunkirk 240010288 O-Ring is a genuine OEM replacement seal engineered specifically for the high-thermal demands of modern hydronic heating. Featuring a rectangular cross-section dimensioned at .15" x .15", this part provides superior surface contact compared to standard round gaskets, ensuring a gas-tight, leak-free union in condensing boiler applications. Built from high-grade silicone with an outside diameter (OD) of 3.65 inches, it maintains critical elasticity and compression set resistance across a wide temperature spectrum. This OEM boiler gasket is a direct-fit component for Dunkirk VLT series models (including DKVLT-150NG and DKVLT-200NG) and compatible Utica residential boilers. By using factory-authorized heating parts, you protect the heat exchanger's integrity and maintain the peak efficiency ratings required for commercial and residential HVAC service.
Key Benefits
- Precision Rectangular Profile: The .15" square cross-section ensures maximum surface area contact to prevent bypass leaks in pressurized systems.
- Thermal Stability: Heavy-duty silicone material resists hardening and cracking even under high-temperature cycling common in condensing boilers.
- Verified Compatibility: Direct replacement for Utica and Dunkirk boiler components, ensuring a perfect seat in the gasket groove.
- System Reliability: Genuine OEM 240010288 construction helps prevent moisture and combustion gas leaks that can lead to corrosion or sensor failure.
Common Questions
Is the 240010288 O-ring interchangeable with standard round seals?
No. This part features a specific rectangular silicone seal profile designed for the precision grooves found in Utica and Dunkirk equipment. A round O-ring would not provide the same sealing surface, potentially leading to immediate leaks if substituted.
What boiler models specify this rectangular O-ring?
This 3.65" OD gasket is standard for several high-efficiency models, notably the Dunkirk DKVLT-150 and DKVLT-200 series. Always check the specific parts manual for your unit's serial number to confirm this is the correct service part.
Does this seal require silicone grease during installation?
While often recommended by veterans to prevent binding, refer to the specific Utica-Dunkirk service instructions for your boiler model to determine if a lubricant is required for this particular high-heat silicone application.
