The AirCraft SG-BD-A5 Fitting is a compact adaptor designed to convert a 1/8" female connection to a 1/4" male connection, helping you connect hoses, regulators, moisture traps, and other accessories properly—without stacked adaptors or dodgy thread mashups.

A clean bridge between 1/8" airbrush fittings and 1/4" air line hardware This adaptor helps you integrate standard airbrush hoses and accessories into compressor/regulator systems that use 1/4" fittings, keeping the setup compact and reliable.
