AirCraft Reducer Brass 1/8x1/4 Male/Female (SB1218)
At a Glance: Brass reducer adaptor with 1/8 x 1/4 male/female threads for compact pneumatic connections.
The AirCraft SB1218 brass reducer is a compact adaptor designed to connect pneumatic components while stepping between 1/8 and 1/4 thread sizes, using a male/female configuration. It’s ideal for compressed-air assemblies such as gauges, regulators, valves, manifolds and air tool accessories where you need to adapt sizes cleanly without stacking multiple fittings. Brass construction adds durability and corrosion resistance, helping keep your pneumatic system reliable, leak-resistant and easy to service in everyday workshop use.
Pneumatic plumbing is easiest when you use the right adaptor, not a tower of “almost fits†fittings. The SB1218 helps you adapt neatly between common small thread sizes while keeping your layout clean and service-friendly.
