AirCraft Nipple Brass 1/4×3/8 Male/Male (SB1212)
At a Glance: Brass nipple adaptor with 1/4 x 3/8 male/male threads for pneumatic connections.
The AirCraft SB1212 brass nipple is a practical adaptor designed to join two female-threaded pneumatic components while stepping between 1/4 and 3/8 thread sizes.
With male/male threads, it’s ideal for building or repairing compressed-air lines on regulators, filters, manifolds, couplers and air distribution hardware—especially when you want a clean, direct connection without stacking multiple adaptors.
Brass construction offers durability and corrosion resistance, making it a solid choice for workshop pneumatic systems where reliable sealing matters.
Pneumatic plumbing is all about correct sizing. The SB1212 helps you adapt cleanly between common thread sizes, keeping your air setup tidy and reducing the chance of annoying air leaks caused by mismatched fittings.
