{"product_id":"high-temperature-graphite-gaskets-vacuum-casting-flasks","title":"High Temperature Gaskets for Flasks","description":"\u003cp\u003eGraphite gaskets designed for use in vacuum casting applications, providing a reliable seal at the flange and casting chamber. The graphite material withstands temperatures up to 1200°F (649°C), making these gaskets well-suited for the demanding conditions of investment casting. Graphite gaskets are exceptionally long-lasting and remain functional even as they wear down to near paper-thin thickness — as long as they are handled carefully to avoid cracking or breakage.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eGraphite construction withstands temperatures up to 1200°F – 649°C\u003c\/li\u003e\n\u003cli\u003eDesigned to seal the flange and casting chamber during vacuum casting\u003c\/li\u003e\n\u003cli\u003eLong service life — usable even when worn to near paper-thin thickness\u003c\/li\u003e\n\u003cli\u003eAvailable in multiple diameters and thicknesses to fit a range of flask sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eGraphite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum Temperature\u003c\/th\u003e\n\u003ctd\u003e1200°F (649°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eVacuum casting — flange and casting chamber sealing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eAvailable Options\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eDiameter\u003c\/th\u003e\n\u003cth\u003eThickness\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e121.831\u003c\/td\u003e\n\u003ctd\u003e3\"\u003c\/td\u003e\n\u003ctd\u003e1\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e121.832\u003c\/td\u003e\n\u003ctd\u003e3-1\/2\"\u003c\/td\u003e\n\u003ctd\u003e1\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e121.833\u003c\/td\u003e\n\u003ctd\u003e3-3\/8\"\u003c\/td\u003e\n\u003ctd\u003e1\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e121.834\u003c\/td\u003e\n\u003ctd\u003e4-1\/2\"\u003c\/td\u003e\n\u003ctd\u003e1\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e121.835\u003c\/td\u003e\n\u003ctd\u003e4-1\/2\" x 5-1\/2\"\u003c\/td\u003e\n\u003ctd\u003e1\/16\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e121.836\u003c\/td\u003e\n\u003ctd\u003e5\"\u003c\/td\u003e\n\u003ctd\u003e1\/8\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eGraphite gaskets are fragile and subject to breakage if mishandled.
