Overview
EN 3869:2004 defines the required characteristics of seals used in aerospace pipe couplings, loose flanges and related sealing interfaces. The standard applies to seals made of fluorocarbon rubber (FPM/FKM) with an armature in aluminium alloy and targets designers, manufacturers and procurement teams in the aerospace fluid-systems sector. Assembly guidance is provided by TR 4053 and the standard references complementary material and marking standards.
Key Topics
- Scope and purpose: Specifies configuration, materials, bonding and required characteristics for fluorocarbon rubber seals with aluminium armature used in aerospace pipe couplings and loose flanges.
- Materials: References EN 2699 (aluminium alloy 5086) and EN 2798 (fluorocarbon rubber, low compression set, hardness 80 IRHD) for material requirements.
- Bonding: Two-part seals are required to be bonded to ensure structural integrity and reliable sealing performance.
- Dimensions and tolerances: The standard provides dimensional definitions, tolerances and mass guidance (see Figure 1 and Table 1 within the standard) for standardized manufacture and interchangeability.
- Marking and traceability: Marking requirements follow EN 2424 to support product identification, traceability and quality control.
- Technical specification and assembly: Detailed technical specification is provided in EN 4054; assembly recommendations are referenced in TR 4053.
Practical value: EN 3869:2004 helps ensure consistent sealing performance, material compatibility, and manufacturability across suppliers and aerospace programs, reducing leakage risk and simplifying maintenance.
Applications
- Use in aerospace fluid systems where reliable, high-temperature and chemically resistant sealing is required.
- Suitable for pipe couplings and loose flange connections on aircraft and spacecraft fuel, hydraulic or pneumatic lines where fluorocarbon elastomers and aluminium armatures are specified.
- Applicable to component manufacturers, OEMs, and maintenance organizations seeking standard-compliant seals for installation and replacement.
