AirCraft Reducer Brass 3/4" x 1/4" M/F Conical (SB1234)
At a Glance: 3/4" to 1/4" male/female conical brass reducer for stepping between air-line connections
Big line, small connection? Happens all the time in real-world air setups. The AirCraft SB1234 conical brass reducer is the clean, no-fuss fix for stepping from a 3/4" connection down to 1/4" using a male/female (M/F) configuration. It’s ideal for compressors, regulators, filters, manifolds, spray equipment and general pneumatic plumbing—especially when you want a compact adaptor rather than a messy stack of fittings. Made from brass for durability and corrosion resistance, this reducer helps keep your compressed-air system tidy, dependable and easy to service.
AirCraft brass fittings are built for reliable compressed-air connections where sealing and long service life matter. This conical reducer bridges sizes neatly, keeping your airline layout clean and workshop-ready.
Extra Information
- Confirm your thread type/standard and the required M/F orientation 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 flats with the correct spanner—avoid over-tightening.
- After fitting, pressurise gradually and check for leaks using soapy water before putting the system into full operation.
Pro Tip
- When stepping down from 3/4" to 1/4", keep the reducer close to the regulator/manifold where possible—shorter “mixed-size” runs are easier to manage and reduce strain on smaller downstream fittings.
Features
- Brass construction Durable, corrosion-resistant body suited to workshop and industrial environments.
- 3/4" x 1/4" reducer size Steps between two very different connection sizes quickly and neatly.
- M/F (Male/Female) configuration Practical adaptor layout for bridging mismatched fittings.
- Conical sealing style Designed to mate cleanly for a secure, leak-conscious connection when installed correctly.
Benefits
- Instant compatibility fix: Connect mismatched components without replacing hoses, regulators or fittings across the system.
- Cleaner airline layout: A single correct reducer beats a chain of adaptors—fewer joints, fewer leak points.
- Built to last: Brass resists rust and wear, helping your air system stay reliable over time.
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.
