Closing Caps

Closing caps are essential passive components designed to ensure integrity, perfect sealing, and proper operation of hydraulic circuits and reservoirs. Engineered to withstand various operating pressures and fully compatible with the main hydraulic fluids in use, they prevent fluid leakage and protect the system from the ingress of moisture and external contaminants, preserving the volumetric and mechanical efficiency of the installation.

Range of Closing Caps available on LubeTeam

• Filling and Level Control Series: For filling operations and visual fluid monitoring, the Miselli filler cap with dipstick TCAZ/TCASZ series integrates a probe for quick level measurement. The Miselli filler cap TCZ/TCZS series instead offers a structurally robust solution for standard refilling and controlled pressurization.
• Drain and Multifunction Series: Typically positioned at the lower points of tanks or used for draining cycles, the Miselli filler and drain cap TCN/TCNS/TSN series ensures maximum operational versatility in hydraulic layouts.
• Standard Closing Series: To securely and permanently seal unused ports and connections, the range offers several technical variants. The Miselli female closing cap TF-C series is the ideal choice for external threads. The Miselli closing cap TCN-OR series ensures superior airtight sealing in the presence of vibrations thanks to the integrated O-ring gasket. Finally, the Miselli closing cap TCNB series effectively covers most general industrial applications.
• Magnetic Series for Decontamination: For active fluid protection, the Miselli magnetic cap TM series efficiently retains ferrous particles resulting from the normal wear of mechanical components, preventing critical damage to pumps, valves, and actuators.

Application Areas

These components are widely and indispensably used in hydraulic power units, gearboxes, speed increasers, compressors, and machinery for industrial, agricultural, and earthmoving sectors.

Advantages of the Range

The selection offers highly reliable solutions characterized by excellent dimensional stability, thermal resistance, and mechanical strength.
