• Rocker Arm Cover Oil Drain Line Connector: Connects the oil drain fitting on the valve rocker cover to the oil return manifold or tubing.

Why Choose AELSTD2180?

Choosing the Continental™ AELSTD2180 provides the ultimate confidence of installing a part made by a world-renowned engine OEM. When a manufacturer like Continental, with over a century of engine design and production experience, produces an FAA-PMA part, it comes with an implicit guarantee of engineering excellence, material science expertise, and manufacturing quality that is second to none. This hose is a certified, reliable, and cost-effective solution that ensures compliance and safety without compromise.

The material science behind the AELSTD2180's fluid resistance is critical to its function as an FAA-PMA component. To be certified as at least equal to the original, its inner tube must be made from a high-grade elastomer like Acrylonitrile Butadiene Rubber (NBR), or Nitrile. The exceptional performance of NBR in a petroleum-rich environment is a function of its polymer chemistry. The resistance to non-polar solvents (oil and fuel) is directly proportional to the acrylonitrile (ACN) content. The polar nitrile groups (-C≡N) along the polymer chain are chemically dissimilar to the non-polar hydrocarbon molecules of the fluid, effectively repelling them. This prevents the fluid from penetrating the rubber's molecular matrix, which would cause swelling, loss of tensile strength, and eventual failure. This engineered material property ensures the hose maintains its structural integrity and sealing capability throughout its service life in the hostile environment of an engine nacelle.

Note: This hose is a flight-critical component due to its location in the fire zone of the engine compartment. All flexible fluid lines have a finite service life and are subject to degradation from heat, ozone, and fluid exposure. Inspect this hose at every pre-flight and scheduled inspection for any signs of cracking, hardening, swelling, or sponginess. Installation must be performed by a certified A&P mechanic using the correct type of spring or screw-type hose clamps as specified in the maintenance manual.

Documentation

The definitive application and installation eligibility for this FAA-PMA component must be confirmed using the official FAA-PMA database and the Illustrated Parts Catalog (IPC) and maintenance manuals for the specific aircraft model and serial number.
