EN 14420-8:2013/FprA1:2015

Hose fittings with clamp units - Part 8: Symmetrical half coupling (Guillemin system)

This European Standard specifies dimensions, types of connections, quality of materials, marking requirements and testing requirements for hose fittings with symmetrical half couplings (Guillemin system), with mobile locking ring, for hose assemblies with a maximum working pressure of up to 10 bar1) with hose tails according to EN 14420-2 and clamp units according to EN 14420-3. Couplings in accordance with this document serve as link between hoses and connections to transport liquids, solids (e.g. powders, granules) except steam and liquid gas. The working temperature range is -20 °C up to +65 °C. With the Amendment 1 a cross-reference will be added regarding the permissible working pressures and temperature stated in EN 14420-1, 4.3. Furthermore, Figure 1 will be updated.

Overview

EN 14420-8:2013/FprA1:2015 is a CEN European standard covering hose fittings with clamp units - Part 8: Symmetrical half coupling (Guillemin system). It defines the design and verification requirements for symmetrical half couplings with a mobile locking ring used on hose assemblies intended to transport liquids and solids (e.g., powders, granules). The standard excludes steam and liquid gas service and sets the working temperature range at -20 °C to +65 °C. It references related parts of the EN 14420 series for hose tails and clamp units.

Key topics and requirements

• Scope of use: Couplings for hose assemblies transporting liquids and solids, excluding steam and liquid gas.
• Design and dimensions: Defined dimensional requirements for Guillemin-type symmetrical half couplings and mating plugs (see Figure 1 as updated in Amendment A1).
• Types of connections: Specification of coupling types with mobile locking ring (Guillemin system).
• Materials and quality: Requirements for material selection and manufacture to ensure fit, function and durability.
• Marking: Identification and marking requirements for traceability and safe use.
• Testing and performance: Mandatory testing procedures and acceptance criteria to verify pressure performance and leakage characteristics.
• Pressure and temperature limits: The published scope indicates assemblies up to 10 bar (1 bar = 0.1 MPa); Amendment A1 adds cross-references to EN 14420-1 regarding permissible working pressures and temperatures and updates clause wording and figures - users should confirm the latest permissible working pressures in the current edition.

Practical applications

• Use in hose assemblies for bulk liquid transfer, slurry and powder transfer, and similar material handling where a Guillemin-type coupling is preferred for quick connection/disconnection.
• Commonly applied where robust, symmetrical couplings with a mobile locking ring are required for safe, repeatable hose connections.
• Typical settings: transport, processing and distribution systems in industrial plants, mobile tanker or trailer hose connections, and general-purpose fluid/solid transfer where steam and cryogenic liquid services are not involved.

Who should use this standard

• Manufacturers of hose fittings, coupling components and clamp units
• Hose assembly designers and OEMs specifying couplings for systems
• Test laboratories and quality assurance teams performing compliance testing
• Procurement and specification writers requiring harmonized European technical requirements
• Regulatory and safety compliance personnel

Related standards

• EN 14420-1 (general requirements, pressure/temperature guidance)
• EN 14420-2 (hose tails)
• EN 14420-3 (clamp units)

For design, procurement or compliance work, always refer to the latest official EN 14420-8 edition and national adoption texts to confirm current pressure and temperature limits and the updated figures introduced by Amendment A1.
