AirCraft Reducing Manifold Brass 3/8" x 1/2" F/F (SB1251)

At a Glance: 3/8" to 1/2" female-to-female brass reducing manifold for stepping between air-line sizes

When your air system needs a neat step-up from 3/8" to 1/2", a proper reducing manifold keeps the job clean and dependable. The AirCraft SB1251 brass reducing manifold provides a female-to-female (F/F) connection that adapts 3/8" to 1/2", making it ideal for compressors, regulators, manifolds, filters and general compressed-air plumbing where you’re bridging two common sizes. Crafted from durable, corrosion-resistant brass, it’s built for workshop reliability and a tidy, serviceable air-line layout.

AirCraft Brass Fittings – Strong Connections, Clean Layouts

AirCraft brass fittings are designed for dependable compressed-air connections where sealing and longevity matter. This reducing manifold bridges sizes in one compact connector, helping you avoid messy adaptor stacks.

Extra Information

Confirm thread standard/type on your system components to ensure correct fitment before installation.
Use PTFE thread seal tape or a suitable pneumatic thread sealant where applicable to help prevent leaks.
Start threads by hand to avoid cross-threading, then tighten using the spanner flats—avoid over-tightening.
After installation, pressurise gradually and check for leaks using soapy water before full operation.

Pro Tip

When stepping up to 1/2", support the heavier hose/line so it doesn’t pull sideways on the reducer. Good alignment prevents slow leaks and reduces thread wear over time.

Features

Brass construction Tough, corrosion-resistant body for long service life in workshop and industrial environments.
3/8" x 1/2" reducing manifold Steps between two popular pneumatic connection sizes.
F/F (Female/Female) configuration Ideal for joining two male-thread components of different sizes.
Compact connector Helps keep your air-line layout tidy and easier to maintain.

Benefits

Fast compatibility fix: Connect mismatched fittings without replacing hoses, couplers or components.
Fewer leak points: One correct reducer is often more reliable than stacking multiple adaptors.
Stronger, cleaner setup: Helps reduce strain on fittings and improves serviceability around manifolds and regulators.

Safety

Wear eye, ear and dust protection when working around pressurised air systems and air tools.
Depressurise the line fully before removing or installing any fittings.
Do not exceed the pressure rating of your compressor, hose, tools or system components.
Check for leaks after installation and correct immediately—never operate a leaking or unstable air line.
