Nipple Brass 1/8x1/2 M/m

At a Glance: Brass nipple adaptor with 1/8 x 1/2 male/male threads for pneumatic connections.

The AirCraft SB1211 brass nipple is a sturdy adaptor designed to join two female-threaded pneumatic components while stepping between 1/8 and 1/2 thread sizes. With male/male threads, it’s ideal for building or repairing compressed-air lines on regulators, filters, manifolds, couplers and workshop air distribution hardware—especially when you want a clean, direct connection without stacking multiple adaptors. Brass construction makes it a solid workshop choice thanks to its durability and corrosion resistance, helping keep your air system reliable, tidy and service-friendly.

Pneumatic systems love standard sizes… right up until they don’t. The SB1211 helps you adapt from smaller 1/8 components to larger 1/2 connections properly, keeping your setup neat and helping reduce leaks caused by mismatched fittings.
