Description

AirCraft Brass Conical Straight 1/2" Tube x 1/4" M (SB6808B)

At a Glance: Conical tube-to-thread straight fitting: 1/2" tube to 1/4" male connection

When you’re running larger pneumatic tubing and you need a clean connection into a standard port, a proper tube-to-thread fitting keeps everything
neat, strong and leak-conscious. The AirCraft SB6808B brass conical straight fitting adapts 1/2" pneumatic tubing to a 1/4" male-thread port
in a straight-through layout—ideal for workshop air circuits, manifolds, machinery pneumatics and general compressed-air plumbing. Brass construction
delivers durability and corrosion resistance, while the conical connection style is designed to seat securely for reliable sealing when installed
correctly.

• Straight conical design Straight-through layout designed for a secure, leak-conscious connection when fitted correctly.
• Workshop-ready footprint Keeps installations neat and easier to service, even in tighter spaces.

Benefits

• Cleaner installations: Reduces adaptor stacking and keeps tubing runs tidy and serviceable.
• Reliable sealing: Correct fitment helps reduce air loss from leaks and supports consistent system performance.
• Stronger tube support: A proper connector helps manage bigger tube runs more securely than improvised solutions.

Extra Information

• Use with compatible 1/2" pneumatic tubing; cut the tube squarely for best sealing.
• Use PTFE thread seal tape or a suitable pneumatic thread sealant on the 1/4" male thread where applicable.
• Start threads by hand to avoid cross-threading, then tighten using the flats—avoid over-tightening.
• Support the tube run near the fitting to reduce vibration and side-load, especially with larger 1/2" tubing.

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.
