3SLC-C06 - Bombardier OEM Swage Linkage Collar Seal

3SLC-C06 – Bombardier OEM Swage Linkage Collar Seal

Available now on the Airparts.aero Marketplace.

The Bombardier 3SLC-C06 is a high-precision, flight-critical environmental and containment seal specifically engineered for swaged linkage assemblies within the primary flight control and landing gear actuation systems of Bombardier aircraft. As an OEM-certified component, the 3SLC-C06 is designed to interface with the swaged collars of structural control rods, providing a hermetic barrier that protects the internal mechanical joint from the ingress of moisture, de-icing fluids (Type IV), and abrasive particulates.

Constructed from a high-performance fluorocarbon or nitrile elastomer (material specification dependent on the specific system application), the 3SLC-C06 is designed to maintain its seal integrity under the extreme pressure differentials and thermal cycling characteristic of high-altitude flight. This collar seal is an essential element in preventing fretting corrosion and hydrogen embrittlement within the swaged joint, ensuring the long-term reliability of the aircraft's mechanical four-bar linkages and bell-crank assemblies.

Key Features

• Precision-Molded Geometry: Engineered to snap-fit over the swaged collar of the linkage, ensuring a high-interference fit that maintains its seal even under significant angular deflection of the rod.

• Chemical & Fluid Resistance: Specifically formulated to resist degradation from Skydrol (LD-4), turbine oils, and the aggressive surfactants found in modern aircraft cleaning agents.

• Low-Friction Surface Treatment: Features a specialized coating or material property that minimizes parasitic drag on the linkage assembly, ensuring smooth pilot-input feedback and actuator response.

• Wide Temperature Envelope: Capable of maintaining elastomeric memory from -65°F to +275°F, preventing the seal from becoming brittle at cruise altitudes or soft during high-temperature ground operations.

• Integrated Scraper Edge: Designed with a "wiper" profile that actively ejects contaminants during the linear or rotational movement of the linkage.

Applications

The 3SLC-C06 is utilized for Linkage Protection & Lubricant Retention. Its primary roles include:

• Elevator/Rudder Control Rods: Protecting the swaged end-fittings from the moisture accumulation common in the empennage.

• Landing Gear Up-Lock Linkages: Ensuring that hydraulic fluid and environmental grit do not penetrate the mechanical pivot of the lock mechanism.

• Flap Actuation Synchronizers: Sealing the collars of the interconnecting rods to prevent corrosion-induced binding.

Why Choose 3SLC-C06?

Choosing a genuine Bombardier 3SLC-C06 is vital to prevent uncommanded control resistance. Generic or "will-fit" seals often lack the specific cold-flow characteristics and chemical resilience required for high-cycle flight controls. An inferior seal can swell when exposed to hydraulic fluid, causing the linkage to bind or "stiffen," which could lead to autopilot disconnects or increased pilot workload during manual flight.

The 3SLC-C06 functions through the principle of elastomeric radial compression. The seal is designed with a specific volume swell factor that is carefully balanced against the chemical environment of the linkage. In swaged assemblies, the junction between the rod and the collar is susceptible to intergranular corrosion if electrolytes are allowed to bridge the gap. The 3SLC-C06 utilizes a precipitation-strengthened polymer chain that provides high resistance to "compression set"—the tendency of an elastomer to permanently deform under pressure. This ensures that the seal maintains a constant contact pressure against the swaged collar throughout thousands of flight cycles, effectively mitigating the risk of structural degradation caused by galvanic moisture traps.

Note: This is a flight-critical environmental component. Prior to installation, the swaged collar must be cleaned and inspected for existing corrosion or mechanical damage. Do not use sharp tools during installation to avoid nicking the elastomeric surface. Installation must be performed by a certified A&P/AME in accordance with the Bombardier Structural Repair Manual (SRM) or AMM. Ensure the seal is properly seated and "clicked" into place to prevent migration during operation.
