#4 Socketless Hose To 1/8 Male Pipe Fitting

The AEROQUIP #4 Socketless Hose to 1/8 Male Pipe Fitting (model FBM1200) is a straight adapter designed to connect #4 AN hose barbs directly to 1/8-inch NPT male ports without requiring a separate socket or swage fitting. Machined from brass for corrosion resistance, this socketless fitting delivers a reliable, leak-free connection in pneumatic, hydraulic, and fluid transfer systems where quick assembly and minimal port intrusion are priorities.

The socketless design eliminates the need for specialized crimping equipment or socket components, making field repairs and system modifications faster and more cost-effective than traditional JIC or SAE port fittings. The #4 AN hose barb accommodates standard -4 hose (1/4-inch ID), while the 1/8 NPT male thread interfaces directly with engine blocks, manifolds, gauges, and reservoir ports without adapters. Brass construction resists corrosion in moisture-heavy environments and provides excellent temperature stability across typical operating ranges. Weighing just 0.04 lbs, it adds negligible mass while maintaining structural integrity under moderate pressure cycles.

This fitting is commonly used in custom fuel systems, auxiliary cooling circuits, brake bleeder installations, and pneumatic tool setups where NPT ports are present but standard hose-end fittings are unavailable. It's also essential for vintage vehicle restorations and fabrication projects where factory NPT ports must accept modern hose-based supply lines. The straight-through geometry prevents flow restrictions and simplifies routing in tight engine compartments or equipment housings.

Socketless fittings offer practical advantages over crimped swaged fittings: they're reusable, require no specialized tools, and allow hose replacement without discarding the adapter itself. AEROQUIP's proven track record in high-performance hydraulics and aerospace applications ensures this fitting meets rigorous durability standards. Sold individually.
