Miselli Knurled Breather Plug Series TCSZF
The Miselli Knurled Breather Plug Series TCSZF is a Polyamide 66 hydraulic component, designed to ensure stability and resistance at temperatures between -30°C and +100°C. It integrates an oil splash guard for splash protection and a polyurethane foam filter to block impurities. Equipped with an NBR 90 Shore gasket, it ensures optimal sealing. Also available in the TCSZF+A variant with integrated phosphated steel level dipstick, it is ideal for industrial hydraulic systems.
The Miselli Knurled Breather Plug Series TCSZF represents an essential technical solution for managing air venting and protecting tanks within hydraulic systems. Developed to operate in industrial environments, this component integrates filtering functionality and a mechanical barrier in a compact and functional design.
The main structure of the threaded plug with knurled cylindrical head is made of thermoplastic material, specifically Polyamide 66. This configuration gives the component excellent mechanical strength, together with high dimensional stability and excellent impact resistance. The operating temperature range is extended, allowing use in demanding thermal conditions between -30°C and +100°C. The standard color for this line is black; however, for orders of suitable quantities, the cap and body can be supplied in customized colors. Hydraulic sealing at the base of the plug is guaranteed by a sealing gasket equipped with a flat washer made of NBR 90 Shore synthetic rubber, which ensures perfect insulation against any fluid leakage.
The TCSZF series stands out for its dual protection system for hydraulic fluid. The plug is equipped with an oil splash guard incorporated into the design. This baffle acts as a mechanical shield for air venting, effectively protecting it where sloshing oil splashes occur inside the tank. At the same time, the component is equipped with a polyurethane foam air filter. This filtering element is essential for protecting the hydraulic oil from the ingress of dust and other external impurities present in the surrounding environment.
For hydraulic applications requiring direct visual control of the fluid level, the range includes the TCSZF+A version. This variant firmly integrates a level dipstick made of phosphated steel. The standard length of the dipstick supplied in the catalog is 200 mm. To meet specific dimensional design requirements, for minimum quantities of 250 pieces, dipsticks with different sizes can be supplied, complete with marks for precise indication of minimum and maximum levels.
Airflow performance varies according to the selected thread size. The air flow rate “P”, expressed in liters per minute and measured at a pressure of 50 mbar, is divided into the following standard configurations:
G 3/8″ threads: Flow rate of 35 l/min.
G 1/2″ threads: Flow rate of 100 l/min.
G 3/4″ threads: Flow rate of 80 l/min.
G 1″ threads: Maximum flow rate of 250 l/min. The catalog also includes options for reduced spaces, including connections with G 1/4″ threads and M14x1.5 metric connections.
