It features a 1\/8 in. NPT connection with an O-ring seal and is rated for pressures up to 2500 psi (172 bar). Its primary function is to indicate when system pressure exceeds safe limits, allowing lubricant to escape through a vent and protecting the lubrication system from overpressure. The material is not explicitly specified, but similar indicators are typically made from carbon steel or stainless steel.\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;\"\u003eAutomatic Relief Indicator\u003c\/li\u003e\n\u003cli class=\"MsoNormal\" style=\"mso-list: l0 level1 lfo1; tab-stops: list 36.0pt;\"\u003e1\/8 in.
