The product is a cap of type RQHD, specifically designed for hose holders of the RQH series by Flexa. It serves as a closure component for cable conduit systems, particularly in applications where secure and durable fixation of cables and hoses is required. The cap is made of plastic (polyamide, PA) and is available in black; a grey variant is also available. It is intended for use in industrial, maritime, and rail transport applications, where high requirements for material resistance and fire protection class apply.

Applications
The RQHD cap is used in areas where cable conduit systems must be protected against external influences such as dust, moisture, or mechanical stress. It is particularly suitable for use in shipping, rail transport, and industrial facilities, where certifications such as ASTM E162/662.SMP800-C, Lloyds Register of Shipping, UK-CA, UL_LLC, and EN_45545_HL2 are relevant. The standard EN_45545_HL2 refers to fire protection requirements in rail vehicles, certifying the cap for use in railway installations. Certification by Lloyds Register of Shipping makes it suitable for maritime applications.

Functions and Features in Detail
The RQHD cap is designed as a closure component for RQH hose holders and ensures a secure and tight sealing function. It is screwed onto the hose holder and prevents foreign objects or moisture from entering the cable system. The material polyamide (PA) offers high mechanical strength, resistance to wear and chemical influences, as well as good thermal resistance. The black color is standard, while a grey variant is also offered.

Technology Explained Simply
The cap is made from a thermoplastic polymer (PA), known for its high strength, heat resistance, and chemical resistance. The temperature resistance ranges from -40 °C to +120 °C, making it suitable for use in various climatic zones and industrial environments. The certifications according to ASTM E162/662.SMP800-C, Lloyds Register of Shipping, UK-CA, UL_LLC, and EN_45545_HL2 confirm its suitability for specific application areas, particularly in rail and shipbuilding. The standard EN_45545_HL2 (likely intended: EN_45545_HL2) sets requirements for the fire behavior of materials in rail vehicles, with HL2 representing the highest requirement level.

Compatibility and Accessories
The RQHD cap is specifically designed for hose holders of the RQH series by Flexa. It is available in size AD10,0, indicating the inner diameter of the hose holder.

Installation and Mounting
Installation is done by screwing the cap onto the RQH hose holder. No additional tools or mounting aids are required. The installation is performed at the end of the hose holder to ensure a tight sealing function.

Operational Advantages
The RQHD cap provides a reliable sealing function for cable conduit systems that need protection against external influences. The certifications according to international standards ensure suitability for demanding applications. The choice of polyamide (PA) material ensures long service life and high resistance to mechanical and chemical stresses. The temperature resistance from -40 °C to +120 °C enables use in a wide range of environments, from cold to warm operating conditions.
