Does Intrex Aerospace Manufacture Aerospace Couplers?

The answer is yes. We have been machining aerospace couplers for over 30 years. A general definition of an aerospace coupler is it is a mechanical or fluid connection device that join components, lines, or structures in an aircraft and spacecraft. They are used for delivery of fuel, fluids, and air.

Difference Between Standard and Aerospace Couplers

There is a significant difference between standard commercial and aerospace couplers. What sets aerospace apart is aerospace must deliver reliable couplers that perform under extreme conditions: wide temperature swings, intense vibration, high pressure, and strict weight limits. Manufacturing these couplers requires high-level machining skills, manufacturing experience, precision CNC machine tools and a sophisticated ERP/MRP systems for overseeing the entire manufacturing process.

Different Type Couplers for Different Applications

There are many types of aerospace couplers, designed for specific purposes. Each have unique design criteria (size, geometry, material, weight) specific to application. The major classifications of aerospace couplers are:

• Fluid couplers: Quick-disconnect and self-sealing couplings join hydraulic, fuel, oxygen, and pneumatic lines. Many are designed to close automatically when separated, which limits leakage and contamination.
• Structural couplers: Are made up of multiple components (clamp bands, latches, seals and separation joints), for fuel, oxygen and pneumatic lines.
• Shaft couplers: Flexible or rigid couplings transmit torque between rotating components, such as engines, gearboxes, and actuators, while accommodating slight misalignment and thermal expansion.
• Electrical and data connectors: Often grouped with couplers, these provide sealed, vibration-resistant links for power and signals.

Materials and design

Coupler materials vary widely. We machine couplers in many different sizes and shapes from titanium, stainless steel, inconel, TZM and aluminum alloys. The different applications vary depending on customer speciation. Most are designed for: corrosion resistance, toughness at low and high temperatures, strength-to-weight ratios, all critical criteria in aerospace applications.

Quality Standards

All our machined components flow through the AS 9100D aerospace certification process. AS9100 is the international quality management system (QMS) standard built specifically for the aviation, space, and defense. It fully incorporates the generic ISO 9001 standard and adds stringent industry-specific mandates.
