The product family concerning the <\/span>Miselli Filler Cap TF – TFA Series<\/span><\/b> represents an engineering solution for hydraulic systems requiring reliable components for tank filling and venting<\/span><\/span>. <\/span>The structural design includes an internal thread specifically engineered to allow direct screw-on mounting on threaded filler necks with a corresponding diameter<\/span><\/span>.<\/span><\/p>\n

Operating Principle and Application<\/h3>\n

These mechanical components perform the dual essential function of filler cap for controlled fluid intake and breather for efficiently compensating air volume variations inside the hydraulic circuit<\/span><\/span>. During system operating cycles, incoming and outgoing air is managed to keep internal pressures stabilized. <\/span>The series is strictly intended for the hydraulic components sector and systems designed for fluid contamination control<\/span><\/span>.<\/span><\/p>\n

Construction Features and Materials<\/h3>\n

The load-bearing structure of the cap is entirely made of high-resistance thermoplastic material, specifically polyamide PA66<\/span><\/span>. <\/span>This construction configuration allows the component to steadily withstand a maximum operating temperature of 100\u00b0C<\/span><\/span>. <\/span>To ensure perfect hydraulic sealing and prevent fluid seepage, the device integrates an internal flat sealing gasket made of NBR synthetic rubber with a hardness grade of 70 Shore<\/span><\/span>.<\/span><\/p>\n

The upper cover, supplied as standard, is provided in two color and text variants to identify the fluid: red with the clear wording “OIL” and yellow with the wording “GASOIL DIESEL”<\/span><\/span>. <\/span>The manufacturer also offers the possibility of requesting additional customizations according to the specific requirements of the target system<\/span><\/span>.<\/span><\/p>\n

Details of the Variants: TF and TFA Models<\/h3>\n

The family is divided into two main engineering variants that share the same threaded body:<\/p>\n

    \n
  • \n

    TF Model:<\/span><\/b> Standard component configuration that operates exclusively as a filler and breather cap with internal thread<\/span><\/span>.<\/span><\/p>\n<\/li>\n

  • \n

    TFA Model:<\/span><\/b> Advanced configuration which, in addition to the standard filling and venting functions, includes an integrated level dipstick<\/span><\/span>. <\/span>This measuring dipstick is made of durable galvanized steel and has a diameter of 5 mm, allowing operators to quickly check the fluid level inside the tank visually<\/span><\/span>.<\/span><\/p>\n<\/li>\n<\/ul>\n

    Both versions are available in standardized models: TF\/2 and TFA\/2 with G2″ thread, and TF\/60.2 and TFA\/60.2 versions with M60x2 thread<\/span><\/span>. <\/span>The geometric dimensions for these models indicate an external diameter (D) of 67.5 mm, an h1 height of 15 mm and an h2 height of 30 mm<\/span><\/span>.<\/span><\/p>\n

    Filtration Specifications and Air Flow Rate<\/h3>\n

    Strict airborne contamination control is managed through an air filter built directly into the cap body<\/span><\/span>. <\/span>The primary filtering element consists of polyester-based reticulated polyurethane foam with a filtration grade classified as PPI 60<\/span><\/span>. <\/span>In terms of fluid-dynamic performance and gas exchange, the component guarantees an air flow rate of up to 75 Lt\/min<\/span><\/span>. <\/span>This specific performance value was accurately measured by testing the system at a test pressure of 275 mbar, ensuring correct flow during maximum demand transients<\/span><\/span>.<\/span><\/p>\n
