Miselli IRM Series Protection for Male Quick Couplings

Description

Construction Features and Materials

The Miselli IRM Series protection caps for male quick couplings are essential accessories for safeguarding hydraulic components. These elements are manufactured using thermoplastic elastomer (TPE), a material that provides optimal structural properties for use as protective caps in hydraulic circuits. The components are available in four different colors—red, blue, green, and yellow—facilitating visual identification in complex systems. Technical documentation also indicates suitability for use with industrial fluids such as PAO and diesel.

Specifications and Reference Standards

The product range is divided into three main application categories, ensuring full compatibility with FASTER systems, ISO A systems, and ISO B systems. Each category includes multiple models classified according to reference thread and dimensional parameters, expressed in millimeters as “D” and “d”.

Variants for FASTER Standard

For hydraulic systems based on FASTER standards, five dimensional options are available:

• IRM/14: G 1/4 thread – D: 16.5 mm, d: 20 mm
• IRM/38: G 3/8 thread – D: 21 mm, d: 23 mm
• IRM/12: G 1/2 thread – D: 23 mm, d: 28 mm
• IRM/34: G 3/4 thread – D: 30 mm, d: 36 mm
• IRM/1: G 1 thread – D: 34 mm, d: 38 mm

Variants for ISO A Standard

The ISO A series (identified with “K”) includes the following models:

• IRM/14 K: G 1/4 – D: 12.7 mm, d: 20 mm
• IRM/38 K: G 3/8 – D: 18 mm, d: 23 mm
• IRM/12 K: G 1/2 – D: 23 mm, d: 28 mm
• IRM/34 K: G 3/4 – D: 30.5 mm, d: 36 mm
• IRM/1K: G 1 – D: 36 mm, d: 38 mm

Variants for ISO B Standard

The ISO B series (identified with “H”) includes:

• IRM/14 H: G 1/4 – D: 15.5 mm, d: 23 mm
• IRM/38 H: G 3/8 – D: 20 mm, d: 23 mm
• IRM/12 H: G 1/2 – D: 25.5 mm, d: 28 mm
• IRM/34 H: G 3/4 – D: 32.5 mm, d: 37 mm
