The SL69603 intake hose is a short flexible coupling hose used in aircraft engine induction systems. It connects intake tubes, elbows, or manifold components, providing a sealed and vibration-tolerant air passage between rigid intake sections.

It is typically used in Continental-compatible piston engine intake systems where short rubber couplers are required to absorb engine vibration, thermal expansion, and minor misalignment between metal intake tubes.

Key features include:

PMA intake system coupling hose
Internal diameter: 1-3/4 inch
Length: 2-3/16 inch (short connector sleeve type)
Flexible, oil- and heat-resistant rubber construction
Connects intake tubes and manifold components
Absorbs vibration and thermal expansion in induction system
Maintains airtight seal under engine operating conditions
Designed for aviation piston engine intake systems
Compatible with Continental engine configurations (model-dependent IPC use)
Used in engine induction assembly and maintenance procedures
