General Information

Overview
EN 14420-8:2013+A1:2016 is the CEN European Standard that defines requirements for hose fittings with clamp units - Part 8: Symmetrical half coupling (Guillemin system). It covers dimensions, connection types, materials, marking and testing for Guillemin (symmetrical) half couplings with a mobile locking ring used on hose assemblies. These couplings link hoses to equipment for the transport of liquids and solids (e.g., powders, granules) - explicitly excluding steam and liquid gas. Nominal sizes covered run typically from DN 20 to DN 100. The standard references and complements other parts of the EN 14420 series (notably EN 14420-1, -2 and -3).
Key topics and technical requirements
- Scope & use: Specifies Guillemin symmetrical half couplings with mobile locking ring for hose assemblies (interfaces to hose tails per EN 14420‑2 and clamp units per EN 14420‑3).
- Dimensions & gauges: Detailed general dimensions, jaw geometry and two gauge types (Annex A) for DN checks and manufacturing tolerances.
- Connection types: Hose tail, external/internal threaded ends (EN ISO 228-1 thread forms), welding ends and plugs with chain/hooks.
- Materials: Typical materials listed include bronze (CuSn5Zn5Pb5), cast/wrought aluminium alloys (EN AC‑42100 / EN AW‑6082), and stainless steels (e.g., 1.4404, 1.4401). Material selection must meet mechanical/chemical properties for service conditions.
- Gaskets: Main gasket options: NBR (nitrile), FPM (fluoro rubber), PTFE; thread gasket options include PUR, PTFE, NBR, FPM, EPDM. Gaskets must be non‑asbestos and compatible with conveyed media.
- Pressures & temperatures: The scope indicates working temperature range for NBR gaskets of −20 °C to +65 °C. The document also includes pressure figures in Clause 4.1 (test and burst pressures) - consult the full standard and EN 14420‑1 for applicable working pressure limits and conformity statements.
- Marking & traceability: Bodies should be durably marked with EN 14420-8, manufacturer/trademark, type and nominal size, and material number (at least for stainless steel).
- Testing & quality control: Type testing and QC follow EN 14420‑1 requirements (type testing, dimensional and pressure tests).
Applications
- Industrial hose assemblies for handling liquids and solids (e.g., chemical transfer, bulk powder transfer, general industrial fluid handling)
- Quick‑connect / symmetrical coupling applications where a Guillemin system is preferred for ease of alignment and sealing
- Hose manufacturers, assembly workshops and plant engineers specifying reliable hose-to-equipment interfaces
Who uses this standard
- Hose and coupling manufacturers (design, production, material selection)
- Specification writers and procurement teams for industrial fluid systems
- Quality, inspection and testing laboratories (dimensional and pressure testing)
- Plant engineers, maintenance teams and system integrators
Related standards
