90 Male Elbow #4 To 3/8 Npt Steel Fitting

The AEROQUIP 90 Male Elbow #4 to 3/8 NPT Steel Fitting (FCM2618) is a precision hydraulic adapter designed for high-pressure fluid power systems where reliable connections are critical. This 90-degree elbow fitting transitions from a #4 AN male port to a 3/8-inch NPT male port, making it essential for hydraulic equipment, aircraft systems, industrial machinery, and mobile fluid power applications where space constraints or system architecture require angled connections.

Constructed from steel with zinc plating, this AEROQUIP fitting delivers corrosion resistance and durability in demanding environments. The 90-degree elbow configuration eliminates the need for separate tubing bends, reducing system complexity and potential leak points. The #4 AN male connection accommodates SAE J518 standard hoses and adapters, while the 3/8-inch NPT male thread provides compatibility with port fittings across a broad range of industrial and mobile equipment. The zinc plating extends service life in applications exposed to moisture, humidity, or corrosive atmospheres.

This fitting serves technicians, equipment manufacturers, maintenance professionals, and system integrators who require proven, standardized hydraulic connections. Whether configuring pilot lines, control circuits, or main pressure passages, the AEROQUIP FCM2618 adapter simplifies assembly while maintaining the reliability expected in hydraulic systems where failure is not an option. At 0.2 lbs, it integrates into compact spaces without adding significant weight.

AEROQUIP fittings are engineered to SAE J518 standards and are recognized across the aerospace, agricultural, construction, and industrial sectors. The elbow design is particularly valuable in retrofit applications, system modifications, and equipment repair where existing port locations demand angled entry.
