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.
Itâs 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.
