It is typically constructed from metal and functions as a safety device that ruptures at a set pressure to protect equipment from overpressure. Its intended use is within GRACO lubrication systems, specifically as a rupture-to-atmosphere indicator for divider valves.\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 (0.375 in, 10 mm diameter)\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eMaximum working pressure: 7300 psi (503 bar, 50.3 MPa)\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eFor use with MJ, MSP, MHH, and MXP Divider Valves\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eColor-coded (Blue) for easy identification\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eSingle-piece design for reliability\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eUsed as a safety device to prevent equipment damage from overpressure\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003eEasy to replace\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eApplications:\u003c\/b\u003e\u003cbr\u003eUsed in GRACO lubrication systems as a rupture-to-atmosphere indicator for divider valves, particularly in applications where system pressures exceed 2,500 psi.
