Utica-Dunkirk 1250014 Gasket

The Utica-Dunkirk 1250014 Gasket is a critical component for maintaining the integrity of high-temperature combustion seals in hydronic heating systems. Engineered from 100% Grafoil flexible graphite, this gasket provides superior surface conformity and thermal stability, outperforming standard elastomeric materials in demanding environments. Designed specifically for compatibility with Utica Dunkirk boiler parts and series such as the Q90 and Q95M, the 1250014 facilitates a precise, leak-proof seal on burner flanges and flue adapters where thermal cycling and chemical resistance are non-negotiable.

This boiler gasket replacement utilizes a braided Grafoil design that remains chemically inert and highly resistant to creep relaxation, ensuring that flange loads remain consistent over extended operational cycles. Unlike traditional fiber gaskets, Grafoil effectively manages heat transfer with a sublimation point reaching up to 6000°F in non-oxidizing atmospheres, making it the ideal HVAC gaskets solution for professionals managing industrial and residential heating infrastructure. Whether you are performing routine boiler maintenance or a critical heating system repair, utilizing this OEM-spec component ensures a reliable seal against fluids and gases without the risk of crystallization or brittle failure.

• High-Temperature Resilience: Engineered to withstand extreme thermal conditions typical of modern boiler combustion chambers.
• Superior Conformability: The Grafoil material naturally adapts to irregular flange surfaces, providing an airtight seal even under low compression loads.
• Chemical Resistance: Naturally inert to most acids, alkalis, and heat transfer fluids, preventing degradation from combustion byproducts.
• Structural Stability: Minimal creep relaxation ensures long-term leak prevention and reduces the need for frequent bolt re-torquing.

• What units are compatible with part 1250014? This gasket is primarily utilized in Utica-Dunkirk high-efficiency boilers including the Q90 and Q95 series for burner and flue sealing.
• Why use Grafoil over standard fiber gaskets? Grafoil offers better thermal conductivity and does not become brittle at high temperatures, which is essential for preserving the pressure vessel seal.
• Is this part suitable for steam applications? Yes, flexible graphite is highly effective in steam environments due to its resistance to oxidation and high-pressure sealing capabilities.
