Overview
EN 14420-5:2013 is a CEN European standard that specifies requirements for hose fittings with clamp units - Part 5: Threaded connections. It covers hose fittings built according to EN 14420‑1 using a union nut and pipe threads per EN ISO 228‑1, and hose tails with male pipe thread per EN 14420‑2. The standard defines maximum working conditions: 25 bar working pressure and 65 °C working temperature. EN 14420‑5 is intended for designers, manufacturers, purchasers and conformity assessors of hose assemblies and industrial fluid transfer systems.
Key topics and technical requirements
- Scope & applicability: Threaded hose fittings and hose tails for clamp‑unit systems with union nuts and male pipe thread in nominal sizes (DN) and corresponding thread sizes (G ½ … G4).
- Dimensions & designation: Defined end‑to‑end dimensions, nominal sizes (DN), and ordering designations for hose tails and union nuts to ensure interchangeability.
- Threads & gaskets: Uses pipe thread dimensions and tolerances from EN ISO 228‑1; specifies thread gaskets (flat faced gasket for these threads) and their dimensions.
- Materials & surface finish: Permitted materials include various steels, stainless steels and copper‑zinc alloys; surface finishes include electroplated zinc for non‑alloy steel and chrome/tin plating for brass per EN ISO 4042. Manufacturer discretion applies for other finishes if agreed.
- Union nuts & mechanical parts: Forms and dimensions for union nuts (several forms A–D), details on balls and internal fittings where applicable.
- Marking, testing & quality control: Requirements for marking, type testing and production quality control procedures to maintain safety and traceability.
- Limits: Explicit operational limits (25 bar, 65 °C) and reference to standards for manufacturing tolerances and material specifications.
Practical applications and users
- Manufacturers of hose fittings, clamp units and hose assemblies use EN 14420‑5 to design and produce interchangeable threaded connections.
- Engineers and specifiers select compliant components for chemical, petrochemical, food & beverage, and general industrial fluid systems where clamp‑unit hose fittings are used.
- Procurement and inspection teams rely on the standard to verify dimensional compatibility, material selection and testing requirements.
- Testing laboratories and conformity assessors perform type tests and quality control in accordance with the standard’s provisions.
Related standards
