This gasket seals the base of the sylphon assembly, maintaining pressure integrity and preventing leaks at the mounting interface. It is a direct service part used by licensed boiler technicians and HVAC mechanics performing maintenance or repair on hydronic heating system controls. Proper sealing at the low water cut off base is critical to safe boiler operation, as these controls protect against dry-fire conditions.\u003c\/p\u003e\n\u003cp\u003eThis gasket is specified for E-28 and 63 Series low water cut off assemblies, making it relevant to residential and light commercial hydronic boiler installations where McDonnell Miller-style controls are in service.

Shut down and depressurize the boiler system completely before removing any low water cut off components. Inspect the mating surfaces for corrosion or damage before seating the new gasket, and do not overtighten fasteners, as this can distort the sealing surface. All work on boiler controls should conform to applicable local codes and manufacturer service documentation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Sylphon Base Gasket for Low Water Cut Off\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Series\u003c\/strong\u003e: E-28 and 63 Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel Reference\u003c\/strong\u003e: CO-11\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: XYLEM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 302500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"XYLEM","offers":[{"title":"Default Title","offer_id":51467578999090,"sku":"302500","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945729.jpg?v=1783906907","url":"https:\/\/voomisupply.com\/products\/xylem-302500-sylphon-base-gasket-low-water-cut-off","provider":"Voomi Supply","version":"1.0","type":"link"}
