It provides a heat-resistant, fuel-tight seal between mating components such as fuel pipe fittings or pump connections, helping prevent leakage of fuel or air that could reduce heater performance or create unsafe conditions. This O-ring is manufactured from materials matched to the original equipment so it fits directly in place during routine service or repair without modification.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is intended for use when the existing seal shows signs of wear, cracking, compression set, or hardening that can compromise the integrity of fuel or fluid connections. Replacing worn O-rings restores proper sealing and helps maintain consistent fuel delivery and safe combustion operation. Installation should follow model-specific service documentation to ensure the O-ring is seated correctly and the mating surfaces are clean before securing connections.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat’s Included:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOne (1) Toyotomi sealing O-ring for compatible Toyostove models.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Limits:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFor replacement use only on designated Toyotomi heater models; install with the heater powered off and ensure clean mating surfaces before seating the O-ring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCompatible with Toyotomi Toyostove models L56, L56-MH, L56-CA, L560, L300, L530, and L730 requiring the 20478568 O-ring in fuel or fluid connections.\u003c\/p\u003e","brand":"Susitna Energy Solutions","offers":[{"title":"Default Title","offer_id":48960664207615,"sku":null,"price":1.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/0092\/3647\/files\/Screenshot2026-08-06121934.png?v=1786047685","url":"https:\/\/www.susitnaenergy.com\/products\/toyotomi-o-ring-p4-20478568","provider":"Susitna Energy Solutions","version":"1.0","type":"link"}
