The JA158 M3/8" to F1/4" Thread Reducer is a precision-machined brass fitting designed to reduce a 3/8" female connection to accommodate a 1/4" male threaded component. Finished with a durable chrome/nickel plating, this adapter provides maximum resistance against surface oxidation, corrosion, and wear in demanding pneumatic and fluid systems.
Featuring a sturdy hexagonal body for easy tightening with a standard wrench, the JA158 adapter ensures a secure, leak-free joint across compressed air lines, pressure gauges, HVAC circuits, and water distribution systems.
