At a Glance; Adaptor fitting – 1/8" BSP female to 1/4" BSP male for airbrush and pneumatic connections
Airbrush gear is famous for mixing sizes: the airbrush world often runs 1/8" connections, while compressors and regulators love 1/4". 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.
Extra Information
Confirm thread standard before ordering—BSP and NPT threads are not interchangeable and can leak or damage threads if forced.
Start threads by hand to avoid cross-threading, then tighten gently—small fittings can strip if overtightened.
After installation, test for leaks using soapy water to confirm a proper seal.
Pro Tip
Build your airbrush setup with as few adaptor joints as possible. Every extra connection is another chance for a tiny leak and pressure fluctuations.
Features
1/8" female to 1/4" male adaptor Converts between common airbrush and compressor/regulator connection sizes.
Compact fitting design Keeps your air line setup tidy and reduces bulky adaptor stacks.
Ideal for airbrush stations Useful for hoses, regulators, moisture traps, and accessory connections.
Benefits
Improves compatibility: Connect mixed-size components properly with a correct, secure fitting.
Helps reduce leaks: Fewer joints and correct thread engagement support steadier pressure and smoother spraying.
Safety
Wear eye protection when working with compressed air fittings.
Depressurise the air line before fitting or removing adaptors.
Do not overtighten—excess force can strip threads or damage sealing faces.
Check for leaks after installation—leaks can cause unstable pressure and inconsistent spraying.
