Aircraft Brass Conical Str. 3/8'Tube X 1/8' M

AirCraft Brass Conical Straight 3/8" Tube x 1/8" M (SB6806A)

At a Glance: Conical tube-to-thread straight fitting: 3/8" tube to 1/8" male connection

Sometimes a pneumatic layout throws you a curveball: a larger 3/8" tube run on one side and a smaller 1/8" threaded port on the other.
The AirCraft SB6806A brass conical straight fitting handles that transition neatly, connecting 3/8" pneumatic tubing to a 1/8" male-thread
port in a straight-through layout. Itâs ideal for manifolds, air preparation units, control circuits and general compressed-air plumbing where you
want a compact, serviceable connection. Brass construction provides durability and corrosion resistance, while the conical connection style is designed
to seat securely for reliable sealing when installed correctly.

Specifications

Features

• Brass construction Durable, corrosion-resistant body suited to workshop and industrial environments.
• Tube-to-thread adaptor Connects 3/8" tubing to a 1/8" male-thread port in one compact fitting.
• Straight conical design Straight-through layout designed for a secure, leak-conscious connection when fitted correctly.
• Space-saving solution Reduces adaptor stacking and keeps installations neat and serviceable.

Benefits

• Neater installations: Creates a direct tube-to-port connection with fewer parts and less clutter.
• Quicker servicing: A purpose-made fitting simplifies maintenance and future line changes.
• More reliable performance: Correct sealing helps reduce air loss from slow leaks and supports consistent operation.

Extra Information

• Use with compatible 3/8" pneumatic tubing; cut the tube squarely for best sealing.
• Use PTFE thread seal tape or a suitable pneumatic thread sealant on the 1/8" male thread where applicable.
• Start threads by hand to avoid cross-threading, then tighten using the flatsavoid over-tightening.
• Support the tube run near the fitting to reduce vibration and side-load, especially with larger 3/8" 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.
