Reducer Brass 3/8x1/2 M/f

At a Glance: Brass reducer adaptor with 3/8 x 1/2 male/female threads for stepping between pneumatic fitting sizes.

The AirCraft SB1225 brass reducer is a compact adaptor designed to connect pneumatic components while stepping between 3/8 and 1/2 thread sizes, using a male/female configuration. It’s ideal for compressed-air assemblies such as regulators, filters, manifolds, valves and couplers where you want a clean size transition 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.

Moving from 3/8 components into a 1/2 air circuit is common in workshop air distribution. The SB1225 helps you step up neatly, reducing extra joints and helping improve sealing reliability.
