Reducer Brass 1/4x1/2 M/f

At a Glance: Brass reducer adaptor with 1/4 x 1/2 male/female threads for stepping between pneumatic fitting sizes.

The AirCraft SB1223 brass reducer is a compact adaptor designed to connect pneumatic components while stepping between 1/4 and 1/2 thread sizes, using a male/female configuration. It’s ideal for compressed-air assemblies such as couplers, regulators, filters, valves and manifolds where you need 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.

When a 1/4 tool-side component needs to connect into a larger 1/2 air circuit, a proper reducer keeps the build neat. The SB1223 helps you step up cleanly, reducing extra joints and improving sealing reliability.
