EN 2606:2009 - Aerospace series - 60° interface for adaptors, threaded, with lockring - Geometric configuration

Overview

EN 2606:2009 - "Aerospace series - 60° interface for adaptors, threaded, with lockring - Geometric configuration" is a CEN standard that defines the dimensional and geometric requirements for metric-size, 60° conical sealing threaded adaptors with a lockring, used in aerospace fluid systems. The standard covers adaptors assembled with an elastomer O‑ring (per EN 2607) and applies to couplings selected for a nominal pressure of 28 000 kPa (28 MPa).

Key topics and technical requirements

  • Geometric configuration and dimensions: Specifies the interface geometry and dimensional characteristics (see Figure 1 and Table 1 in the standard). Table 1 provides port dimension codes tied to nominal pipe outside diameters and the corresponding thread, diameter and length parameters.
  • 60° conical sealing surface: Defines the mating surface geometry for reliable metal-to-metal/conical sealing combined with an elastomer O‑ring.
  • Threading and fit: Threads conform to MJ thread requirements (ISO 5855‑1 and ISO 5855‑3 where applicable) for compatibility and interchangeability.
  • Lockring and installation position: Specifies lockring location after installation in the port (reference to EN 2602 for port geometry and installation criteria).
  • Surface finish: Surface roughness requirements are referenced to the geometric drawing (Figure 1) unless other design documentation specifies different values.
  • Designation and identification: Provides a designation format (example: EN2606‑10 plus port code) to identify specific adaptor configurations.

Applications

EN 2606:2009 is intended for use where a metric-size coupling with a 60° conical sealing surface has been selected in aerospace fluid systems. Practical applications include:

  • Design and specification of threaded adaptors with lockrings for aircraft fluid lines
  • Ensuring dimensional interchangeability across suppliers and maintenance parts
  • Selecting correct mating ports and O‑ring assemblies for systems rated to 28 000 kPa
