AirCraft Brass Conical Straight 1/4" Tube x 3/8" M (SB6804C)
At a Glance: Conical tube-to-thread straight fitting: 1/4" tube to 3/8" male connection
When a 1/4" pneumatic tube run needs to connect into a larger 3/8" port, you want a fitting that does it cleanly—no adaptor tower, no drama. The AirCraft SB6804C brass conical straight fitting adapts 1/4" tubing to a 3/8" male-thread connection in a straight-through layout, making it ideal for manifolds, air preparation units, control circuits and general compressed-air plumbing where a tidy transition is essential. Brass construction provides durability and corrosion resistance, while the conical connection style is designed to seat securely for a leak-conscious seal when installed correctly.
AirCraft tube fittings are built for practical, serviceable pneumatic layouts. This straight connector gives you a compact transition from 1/4" tube to a 3/8" male-thread port without bulky adaptors.
Extra Information
- Use with compatible 1/4" pneumatic tubing; cut the tube squarely for best sealing.
- Use PTFE thread seal tape or suitable pneumatic thread sealant on the 3/8" male thread where applicable.
- Start threads by hand to avoid cross-threading; tighten using the flats—avoid over-tightening.
- Support heavier downstream fittings/hoses to reduce side-load on the connector and help seals last longer.
Pro Tip
- When stepping up to 3/8", don’t let the bigger hose hang off the fitting. Add a clip or bracket close to the port—alignment is the easiest leak-prevention “upgrade” you’ll ever do.
Features
- Brass construction Tough, corrosion-resistant body suited to workshop and industrial environments.
- Tube-to-thread adaptor Connects 1/4" tubing to a 3/8" male-thread port in one compact fitting.
- Straight conical design Straight-through layout designed for a secure, leak-conscious connection.
- Compact footprint Ideal for tight spaces in control panels, manifolds and pneumatic assemblies.
Benefits
- Cleaner installations: Reduces adaptor stacking and keeps tubing runs tidy and serviceable.
- Fast compatibility: Lets you connect small-bore tube lines into larger ports with minimal fuss.
- More reliable sealing: Proper fitment helps reduce air loss from leaks and supports consistent system performance.
Safety
- Wear eye protection when working with pressurised air lines.
- Depressurise the system fully before cutting, removing or installing tubing and fittings.
- Do not exceed the pressure rating of your tubing, fittings or system components.
- Check for leaks after installation and correct immediately to prevent hose whip or unexpected tool actuation.
