Aircraft Reducing Manifold Brass 1/4X3/8 F/F

Description

AirCraft Reducing Manifold Brass 1/4" x 3/8" F/F (SB1249)

At a Glance: 1/4" to 3/8" female-to-female brass reducing manifold for stepping between air-line sizes

Air systems love mixing standards—right when you don’t have time for it. The AirCraft SB1249 brass reducing manifold is the tidy solution, giving you
a female-to-female (F/F) connector that steps from 1/4" to 3/8". It’s ideal for adapting mismatched pneumatic components on compressors,
regulators, filters, manifolds and general compressed-air plumbing without building an awkward stack of adaptors. Made from durable, corrosion-resistant
brass, it’s built for workshop reliability and a cleaner, more serviceable air-line layout.

Features

• Brass construction Tough, corrosion-resistant body for long service life in workshop and industrial environments.
• 1/4" x 3/8" reducing manifold Steps between two common pneumatic connection sizes.
• F/F (Female/Female) configuration Ideal for joining two male-thread components of different sizes.
• Compact connector Keeps your air-line layout tidy and easier to maintain.

Benefits

• Fast compatibility fix: Connect mismatched fittings without replacing your existing hoses or components.
• Fewer leak points: One proper reducer is often more reliable than stacking multiple adaptors.
• Cleaner system layout: Helps reduce clutter around regulators, filters and manifolds for better serviceability.

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.

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.
