Hydraulic Filters and Accessories
Efficiency, cleanliness and protection for hydraulic circuits
Hydraulic filters are essential to ensure the durability and reliability of hydraulic systems. They remove solid and liquid contaminants, protecting pumps, valves and actuators from wear and failures, improving efficiency and reducing maintenance costs.
Fluid System distributes the complete MP Filtri range, an international leader in hydraulic filtration, offering solutions for high-pressure, return-line and suction applications, as well as filter elements and monitoring accessories such as indicators and caps. MP Filtri products stand out for construction quality, filtration efficiency and reliability in every operating condition.
When maintaining or replacing hydraulic filters, product selection often starts from specific application codes or from filter elements already installed on the system. Correct identification of the series and configuration is essential to ensure compatibility and adequate performance.

Typical application codes and recurring configurations
When selecting or replacing MP Filtri hydraulic filters, codes such as STR 070 2 S G1 and STR 100 2 S G1 are frequently searched, often entered as STR0702SG1 and STR1002SG1, referring to suction strainers for pump protection. The code CS 050 P10 A, often entered as CS050P10A, is also commonly searched for replacement spin-on filter cartridges. For return-line filtration, the code MPF 180 1 A G1 P10, often entered as MPF1801AG1P10, is frequently searched as a typical semi-immersed return filter for tank installation.
