The Miselli Breather Plug Series TK represents an advanced technical and engineering solution for control and venting in hydraulic components<\/span><\/span>. <\/span>This specific element has been meticulously designed to operate inside oil chambers where significant fluid sloshing occurs<\/span><\/span>. <\/span>In these critical operating conditions, the component neutralizes the resulting risk of oil escaping through the hole, ensuring the safety, efficiency, and cleanliness of the entire hydraulic system<\/span><\/span>.<\/span><\/p>\n

Operating Principle and Internal Labyrinth<\/h3>\n

The functional core of these extended breather plugs lies in their dynamic fluid containment system<\/span><\/span>. <\/span>The combined action of specific internal splash guards, which create a true internal labyrinth, and the calibrated breather hole with a diameter of 2.5 mm, very effectively prevents liquids from escaping<\/span><\/span>. <\/span>Furthermore, the breather hole is strategically positioned and raised at the top of the plug, maximizing the distance from the moving fluid and optimizing the aeration process and contamination control<\/span><\/span>.<\/span><\/p>\n

Construction Features and Materials<\/h3>\n

From a strictly structural standpoint, the component is configured as a threaded breather plug with an extended knurled cylindrical grip<\/span><\/span>. <\/span>This particular geometry greatly facilitates gripping and manual tightening or removal operations during maintenance phases<\/span><\/span>. <\/span>The entire body of the device is molded from a thermoplastic material with high mechanical strength, specifically Polyamide 66<\/span><\/span>. <\/span>The standard visual finish includes a black body topped with a small red cap bearing the wording “OIL” for clear and unmistakable identification of the topping-up point in the hydraulic circuit<\/span><\/span>.<\/span><\/p>\n

Thermal and Mechanical Sealing Specifications<\/h3>\n

Hydraulic sealing at the connection point is securely guaranteed by the use of a flat washer sealing gasket<\/span><\/span>. <\/span>This technical gasket is made of FASIT 202 fiber, a material that ensures reliable insulation against micro-leaks of fluid and pressure<\/span><\/span>. <\/span>Thanks to the excellent properties of the thermoplastic material used and the high quality of the gasket at the base, the component supports a maximum operating temperature of 100\u00b0C, making it perfectly suitable for intensive and prolonged industrial use<\/span><\/span>.<\/span><\/p>\n

Dimensions and Available Variants<\/h3>\n

To ensure maximum compatibility and flexibility with different system architectures, the TK series plugs are available in multiple dimensional configurations<\/span><\/span>. <\/span>The catalog variants include Gas thread options, specifically the TK\/14 (G 1\/4″), TK\/38 (G 3\/8″), and TK\/12 (G 1\/2″) models<\/span><\/span>. <\/span>These solutions are complemented by metric thread versions, namely the TK\/16.15 (M 16×1.5) and TK\/18.15 (M 18×1.5) models<\/span><\/span>. <\/span>All configurations maintain a constant thread height (h2) of 12 mm, while the overall height of the external section (h1) varies from 55 mm to 65 mm and the grip diameter (D) from 20 mm to 28 mm, adapting proportionally to the connection size to offer versatile construction solutions<\/span><\/span>.<\/span><\/p>\n
