Description

AirCraft Brass Conical Straight 5/16" Tube x 3/8" M (SB6805C)

At a Glance: Conical tube-to-thread straight fitting: 5/16" tube to 3/8" male connection

When a 5/16" tube run needs to connect into a bigger 3/8" threaded port, you want a fitting that does the job cleanly—without a bulky stack of
adaptors. The AirCraft SB6805C brass conical straight fitting is a compact tube-to-thread connector that links 5/16" pneumatic tubing to a 3/8"
male thread in a straight-through layout. It’s ideal for neat pneumatic installations on manifolds, air prep units, control circuits and general
compressed-air plumbing where reliable sealing and serviceability matter.

Specifications

Features

• Brass construction Durable, corrosion-resistant body suited to workshop and industrial environments.
• Tube-to-thread adaptor Connects 5/16" 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 when fitted correctly.
• Space-saving solution Reduces adaptor stacking and keeps installations neat and serviceable.

Benefits

• Cleaner installations: Creates a direct step-up connection from tube to port with fewer parts and less clutter.
• Quicker maintenance: A compact, purpose-made fitting makes future servicing and line changes simpler.
• More reliable performance: Good fitment and correct sealing help reduce air loss from slow leaks.

Extra Information

• Use with compatible 5/16" pneumatic tubing; cut the tube squarely for best sealing.
• Use PTFE thread seal tape or a suitable pneumatic thread sealant on the 3/8" male thread where applicable.
• Start threads by hand to avoid cross-threading, then tighten using the flats—avoid over-tightening.
• Support heavier hoses/components near the port to reduce side-load on the fitting and help seals last longer.

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.
