Closing Cap Miselli TCN-OR Series

Description

The Miselli Closing Cap TCN-OR Series is a technical solution specifically developed for the field of accessories for hydraulic components and fluid contamination control. It is a hex-head threaded element designed to ensure secure sealing of hydraulic circuits. Production is handled by Miselli, a company based in Reggio Emilia with 50 years of experience, reliability, and innovation in the market. Technical documentation and distribution are handled by Lube Team Hydraulic S.r.l., with operational offices in Airola, Italy.

Construction Features and Material Selection

The primary structure of the component is made of Polyamide 66. This technical polymer has been reinforced through the use of glass fiber. The adoption of these materials gives the cap excellent overall mechanical resistance, making it highly performant at both low and high temperatures. The material also ensures high dimensional stability over time and significant impact resistance during installation or system operation.

Integrated O-Ring Sealing System

The main innovation of this component lies in its gasket system. The cap is equipped with an O-Ring made of NBR synthetic rubber. This O-Ring is physically integrated into the geometry of the hexagonal head. The use of the integrated O-Ring in this position represents a significant engineering advantage: it allows correct hydraulic sealing to be achieved using only moderate tightening torques. This factor reduces stress on the thread and preserves the integrity of the component in the long term.

Performance and Tested Operating Limits

The technical specifications of this plastic cap cover demanding industrial requirements.

• The operating temperature allowed for optimal performance ranges from -30°C to +100°C.

• The component guarantees tested resistance for circuit pressures up to 100 bar.

• These pressure values were validated through laboratory tests carried out at room temperature.

• The 100 bar sealing tests were conducted using a specific fluid, namely ENI OSO VG hydraulic oil.

• The laboratory report relating to these technical tests can be regularly supplied upon request.

Models and Dimensional Specifications

The TCN-OR series is available in three dimensional versions to cover different connections.
