General Information

Overview
EN 14420-3:2013 is the CEN European Standard that defines requirements for clamp units (bolted or pinned) used in hose fittings. It applies to clamp units for hose couplings specified in EN 14420-1 and for use with hose tails per EN 14420-2. The standard sets performance limits including a maximum working pressure of 25 bar and a maximum working temperature of 65 °C, and defines sizes, materials, fasteners, dimensions, marking and type-testing/quality-control expectations.
Key Topics
- Scope and nominal sizes (DN): Clamp unit types covered are K (bolted) and S (pinned). Clamp unit K is specified for DN 15–200; clamp unit S is specified for DN 25–100. Fixing (pinching) ranges are given per DN.
- Design & dimensions: Detailed dimensional tables, tolerances and shell geometries are provided for repeatable manufacture and interchangeability. General tolerances reference EN 22768.
- Materials:
- Stainless steel options (e.g. 1.4401, 1.4404, 1.4408, 1.4581 per EN 10088 / EN 10213).
- Aluminium alloys (e.g. EN AC-42100, EN AC-42200, EN AW-6082) with heat treatment and minimum elongation requirements.
- Copper–zinc alloys (e.g. CW 614 N, CW 617 N per EN 12420).
- Fasteners & pins:
- Bolt/nut classes specified (e.g. 10.9/10 and 8.8/8 depending on DN) with electroplated coatings A2C/A3C per EN ISO 4042.
- For stainless clamp shells, bolts/nuts of stainless groups A4 (per EN ISO 3506) are required.
- Pins specified in stainless grades (e.g. 1.4303, 1.4310) with minimum tensile strength (≥ 600 N/mm²).
- Marking, testing & quality control: Requirements for marking and type testing are defined to ensure traceability and performance; the standard references EN 14420‑1 for certain testing protocols.
Applications / Who Uses It
- Manufacturers of hose fittings and clamp units seeking to supply products compliant across CEN member states.
- Design and procurement engineers specifying hose couplings for low- to medium-pressure fluid systems (max 25 bar).
- Maintenance and safety engineers in industries such as petrochemical, transport, agriculture, food & beverage, and general industrial fluid handling, where standardized hose connections are required.
- Test laboratories and certification bodies performing conformance testing and verification.
