#10 O-ring #12 flare Adt

The AEROQUIP #10 O-ring #12 flare adapter is a straight-thread hydraulic fitting designed to connect AN10 male O-ring (JIC) ports to AN12 male flare ports. This aluminum construction adapter with blue anodized finish handles the critical interface between incompatible port standards in high-pressure fluid systems, making it essential for aircraft, industrial machinery, and performance hydraulic installations where precise port matching is non-negotiable.

The straight configuration eliminates elbow geometry, reducing pressure drop and simplifying line routing in space-constrained installations. AN10 O-ring ports use a tapered JIC thread with a captured elastomer seal for leak prevention, while AN12 flare ports accept a 37-degree flare nut connection. The blue anodized aluminum body resists corrosion while remaining lightweight—critical in aircraft systems where every pound matters. AEROQUIP fittings meet SAE J518 standards, ensuring compatibility across OEM and aftermarket hydraulic systems.

This adapter serves mechanics, hydraulic technicians, and system designers who need to bridge port-size or port-type mismatches without replacing existing components. Common applications include aircraft auxiliary hydraulic circuits, agricultural equipment plumbing, aerospace ground support equipment, and custom performance hydraulic builds. The FCM2954 coupling is sold individually, allowing targeted repairs or custom system assembly without bulk purchasing.

AEROQUIP is a recognized OEM supplier of hydraulic connectors to major aerospace and industrial manufacturers, positioning this adapter as a direct-equivalent replacement part trusted in mission-critical environments.
