Miselli IRF Series Protection for Female Quick Couplings

Description

Technical Specifications and Materials

The Miselli IRF Series protection caps for female quick couplings are specifically designed for use on hydraulic components. The entire range is manufactured using thermoplastic elastomer (TPE) as the raw material. This material ensures the flexibility required for application on fittings, along with the durability needed for operation in industrial environments.

To facilitate visual identification of circuits and simplify maintenance operations, the components are available in four color variants: red, blue, green, and yellow. These protections are part of broader fluid contamination control procedures within hydraulic systems. They are suitable for use in circuits operating with fluids such as PAO and diesel, following standard “open after cleaning” procedures.

Application References and Compliance Standards

The range is divided into three main categories based on application references, ensuring precise mechanical compatibility with different market standards.

FASTER Standard Compatibility

Standard models are designed to match FASTER references.
