Where soft-sheet gaskets would creep, degrade, or blow out, the ASA 1500 holds firm.\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eAt the heart of this gasket's performance is its alternating construction—V-shaped metal plies interlocked with flexible graphite filler layers. This configuration functions like a precision-engineered spring, continuously adapting to thermal cycling, pressure surges, and vibration without losing sealing integrity. The result is a consistently tight seal across the full lifecycle of the installation.\u003c\/p\u003e\u003cdiv\u003e\n\u003cdiv\u003eThe Carbon Steel Inner Ring serves a critical structural function: acting as a compression stop that prevents over-tightening during installation and guards against blowout under extreme forces. Compatible with both raised-face and flat-face flanges, it delivers reliable performance across a wide range of industrial flange configurations.\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\u003cb\u003eSummary:\u003c\/b\u003e \u003cbr\u003e\u003cul\u003e\n\u003cli\u003ePressure Rating: Class 1500 (~255 bar \/ 3,705 psi)\u003c\/li\u003e\n\u003cli\u003eConstruction: Alternating metal plies with flexible graphite filler\u003c\/li\u003e\n\u003cli\u003eInner Ring Material: Carbon Steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eApplications: \u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOil \u0026amp; gas, petrochemical, power generation, boiler connections\u003c\/li\u003e\n\u003cli\u003eFlange Compatibility: Raised-face and flat-face flanges\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Flocon","offers":[{"title":"3\/4\"","offer_id":58737220911488,"sku":"11.SWG.020.1500","price":15.0,"currency_code":"GBP","in_stock":true},{"title":"1\"","offer_id":58737220944256,"sku":"11.SWG.025.1500","price":4.27,"currency_code":"GBP","in_stock":true},{"title":"2\"","offer_id":58737220977024,"sku":"11.SWG.050.1500","price":7.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0524\/4531\/5228\/files\/Spiral_20Wound_20Gasket_20Cast_20Iron_2C_20Stainless_20Steel_20PN16_11.SWG.015.PN16.jpg?v=1764644899","url":"https:\/\/www.flocon.co.uk\/products\/asa-1500-spiral-wound-gasket-carbon-steel-inner-ring","provider":"Flocon Valves Pipes \u0026 Fittings","version":"1.0","type":"link"}
