J-A109 AIRMIXS Threaded Adapter / Reducer Bushing – Male 1/4" to Female 1/2" Thread G / BSP

The J-A109 M1/4" F1/2" is an industrial-grade threaded adapter designed to connect lines or components with unequal thread sizes in pneumatic, hydraulic, and fluid control systems. Featuring an external Male 1/4" thread and an enlarged internal Female 1/2" thread, this fitting enables direct transition between 1/4" manifold ports or valves and larger 1/2" piping or sensor assemblies.

Constructed with precision-machined parallel threads and a integrated hexagonal body for effortless wrench tightening, the J-A109 ensures a leak-tight seal and long-lasting durability under pressure. It is suitable for air preparation units, automation panels, pressure lines, and general fluid distribution networks.
