Manufactured from 304 stainless steel with a black jacket, this flexible tubing comes in a 100-foot coil at a 1-inch nominal diameter. The black coating serves as the protective outer jacket and is standard for identifying this CSST product category. It meets a broad range of national certifications including ANSI LC1, ASTM A240 and E84, CSA 112940, IAPMO 3353, ICC ESR-1879, and UL R18357, confirming compliance with industry safety and performance standards. Domestic manufacture is noted.\u003c\/p\u003e\n\u003cp\u003eCSST like the 25A.WF100 is installed in new construction and retrofit applications where rigid black iron pipe is impractical or where routing flexibility is needed. It runs through walls, floors, and mechanical chases to connect gas meter outlets to appliances including furnaces, water heaters, boilers, fireplaces, and range equipment. The 100-foot coil length reduces the need for field splices on longer runs. Licensed plumbers and gas fitters are the primary installers of this product.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e304 stainless steel corrugated construction provides durability and corrosion resistance in gas distribution service\u003c\/li\u003e\n  \u003cli\u003e1-inch nominal diameter suitable for main trunk or high-demand branch runs\u003c\/li\u003e\n  \u003cli\u003e100-foot coil length reduces field joints on extended installations\u003c\/li\u003e\n  \u003cli\u003eBlack jacket for UV and mechanical protection of the stainless corrugations\u003c\/li\u003e\n  \u003cli\u003eCertified to ANSI LC1, ASTM A240\/E84, CSA 112940, IAPMO 3353, ICC ESR-1879, and UL R18357\u003c\/li\u003e\n  \u003cli\u003eDomestic manufacture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard CSST replacement and new-installation product for natural gas and propane distribution systems in residential and light commercial applications.

Shut off gas supply at the meter and verify zero pressure before cutting or connecting tubing. CSST installations typically require bonding and grounding per applicable electrical and gas codes — consult local authority having jurisdiction for specific requirements. Do not kink, over-bend, or compress the corrugated tubing during routing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 304 Stainless Steel with black jacket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 100 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: ANSI LC1, ASTM A240\/E84, CSA 112940, IAPMO 3353, ICC ESR-1879, UL R18357\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Domestic (USA)\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: ASC ENGINEERED SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 25A.WF100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASC ENGINEERED SOLUTIONS","offers":[{"title":"Default Title","offer_id":51524611113266,"sku":"PIPE1-100","price":17.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3e24e943c266495ca7f5961e3f51756_6303294f-c68d-4c2c-99d4-2e246d8f54d3.jpg?v=1785453063","url":"https:\/\/voomisupply.com\/products\/asc-engineered-solutions-25a-wf100-csst-tubing-1in-100ft","provider":"Voomi Supply","version":"1.0","type":"link"}
