It is constructed to provide a safety mechanism by rupturing at a predetermined pressure, thereby protecting equipment from overpressure. The disk is typically made from a metal alloy suitable for high-pressure applications, though the exact material is not specified in available documentation. Its intended use is within GRACO lubrication equipment to prevent damage caused by excessive system pressure.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eKey Features:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul style=\"margin-top: 0cm;\" type=\"disc\"\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eRupture Disk\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e3\/8 in (9.5 mm) diameter\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eMaximum working pressure: 6400 psi (44.1 MPa)\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eCompatible with GRACO lubrication systems requiring a 3\/8 in rupture disk\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eProvides overpressure protection by rupturing at a set pressure\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eEasy to replace and reset\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eReliable safety mechanism for high-pressure systems\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eColor-coded (Pink) for easy identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eApplications:\u003c\/b\u003e\u003cbr\u003eUsed in GRACO lubrication systems where system pressures may exceed safe operating limits, such as in industrial, mining, and agricultural equipment.
