The \u003cb\u003eLochinvar 100233617\u003c\/b\u003e cover gasket acts as the primary interface seal for the gas air arm, effectively preventing oxygen infiltration or gas bypass that can destabilize burner performance. By utilizing the original \u003cb\u003e100233617\u003c\/b\u003e replacement, technicians ensure that dimensions strictly adhere to factory tolerances for a seamless, reliable fit.\u003c\/p\u003e\u003cp\u003eThis gasket is engineered from high-temperature resilient materials designed to accommodate thermal expansion and vibration during frequent burner cycling. It functions by filling microscopic irregularities between the air arm flange and the mounting surface, ensuring that blower-induced pressure remains consistent throughout the combustion process.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCombustion Integrity:\u003c\/strong\u003e Maintains factory-spec fuel-air ratios by eliminating unwanted air infiltration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Resilience:\u003c\/strong\u003e Resists degradation from constant heat exposure and expansion cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVibration Damping:\u003c\/strong\u003e Protects the intake assembly interface against mechanical stress during blower operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Consistency:\u003c\/strong\u003e Prevents gas bypass to ensure stable blower-induced pressure levels.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Specifically designed for gas air arm assemblies in compatible Lochinvar high-efficiency boiler models requiring air-tight intake maintenance.\u003c\/p\u003e","brand":"LOCHINVAR","offers":[{"title":"Default Title","offer_id":43137696792670,"sku":"100233617","price":82.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/188940441.jpg?v=1786197853","url":"https:\/\/nationalboilersupply.com\/products\/lochinvar-100233617-cover-gasket-gas-air-arm-lg","provider":"National Boiler Supply","version":"1.0","type":"link"}
