Technical Specifications and Materials<\/strong><\/h3>\n

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.<\/p>\n

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 \u201copen after cleaning\u201d procedures.<\/p>\n

Application References and Compliance Standards<\/strong><\/h3>\n

The range is divided into three main categories based on application references, ensuring precise mechanical compatibility with different market standards.<\/p>\n

FASTER Standard Compatibility<\/strong><\/h3>\n

Standard models are designed to match FASTER references.<\/p>\n
