The 629325 tube is an OEM intake manifold tube assembly used in Continental aircraft piston engine induction systems. It routes the air-fuel mixture through the intake manifold to a specific cylinder (commonly cylinder No. 6 depending on engine layout), forming part of the engine’s induction distribution system.

It is a pre-formed rigid aluminum tube designed to maintain exact geometry for correct airflow balance, sealing alignment, and vibration resistance in high-RPM engine operation.

The part is installed in the intake manifold system alongside intake hoses, clamps, gaskets, and other tube assemblies to ensure even mixture distribution across cylinders.

Key features include:

OEM Continental intake manifold tube assembly
Precision-formed rigid tubing for correct airflow routing
Part of engine induction system (intake manifold distribution)
Ensures balanced air-fuel delivery to cylinders
Designed for vibration and thermal cycling environments
Maintains exact factory geometry (not field-bendable)
Used with intake hoses, clamps, and gaskets in full assembly
Installed in specific cylinder routing positions depending on engine model
Compatible with Continental piston engine configurations (IPC-dependent)
Used in certified engine maintenance and overhaul procedures
