The Lycoming LW‑15592‑5‑05 is a small hose clamp used on various Lycoming piston aircraft engines to secure flexible hoses (such as fuel, oil, or drain‑back lines) to fittings. It is typically installed where a positive, secure attachment is needed to prevent hose separation or leakage under pressure, heat, and vibration.

This clamp is often referred to as a “drain‑back clamp” in some catalogs and is an OEM replacement part that fits specific hose diameters in Lycoming engine installations, ensuring reliable retention in systems where fluid flow must be controlled and chafing minimized.
