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 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.

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.
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.
