The indicator plugs produced by MP Filtri represent an essential technical solution for advanced filtration systems, specifically engineered for functions related to clogging indicators and vacuum indicators.<\/p>\n

Operating Principle<\/strong><\/h3>\n

Designed for direct integration into hydraulic circuits, these components act as sealing plugs for sensor ports. Their structural design ensures pressure retention within the circuit, withstanding severe operating loads that vary according to the selected technical series.<\/p>\n

Series Design Features<\/strong><\/h3>\n

The range is divided into four design variants, each defined by precise materials and mechanical tolerances:<\/p>\n

    \n
  • Series T2<\/strong>: Manufactured with a solid phosphated steel body. They require an A\/F 30 wrench and support a maximum tightening torque of 50 N-m.<\/li>\n
  • Series T4<\/strong>: Developed with an anodized aluminum body, ideal for applications where component weight matters. They use an A\/F 19 wrench with a maximum tightening torque limited to 20 N-m.<\/li>\n
  • Series X2<\/strong>: Fully made of AISI 316L stainless steel. This high-strength variant is designed to operate safely at pressures up to 420 bar. Installation requires an A\/F 30 wrench and a maximum tightening torque of 50 N-m.<\/li>\n
  • Series X3<\/strong>: The top-of-the-range solution for very high pressures, made of AISI 316L stainless steel and certified to operate up to 700 bar (exclusively for FZH configurations). Tightening requires an A\/F 30 wrench and a maximum torque of 110 N-m.<\/li>\n<\/ul>\n

    Seal Specifications<\/strong><\/h3>\n

    Perfect hydraulic sealing and compatibility with operating fluids are ensured by a wide selection of elastomer compounds, easily identified through ordering codes:<\/p>\n

      \n
    • Series T2 models can be supplied with HNBR seals (code T2 H) or FPM seals (code T2 V).<\/li>\n
    • The aluminum T4 series is equipped exclusively with NBR seals (code T4 A).<\/li>\n
    • The stainless steel variants of the X2 series offer sealing options in HNBR (X2 H), FPM (X2 V), and MFQ (X2 F).<\/li>\n
    • Likewise, the high-pressure models of the X3 series allow a choice between HNBR (X3 H), FPM (X3 V), and MFQ (X3 F) compounds.<\/li>\n<\/ul>\n

      Applications and Reference Industries<\/strong><\/h3>\n

      These components are intended for use exclusively by technically qualified personnel. As an integral part of MP Filtri technologies for vacuum and clogging indication, these plugs are distributed through a broad global network that includes Canada, China, France, Germany, India, Singapore, the United Arab Emirates, the United Kingdom, and the United States, with headquarters in Italy. It is essential that engineers and technicians strictly follow the indicated tightening torque values to prevent structural damage (from 20 N-m to 110 N-m depending on the model). MP Filtri reserves the right to make technical or commercial modifications to models at any time; therefore, discretionary use by qualified operators is recommended.<\/p>\n
