Aircraft Brass Conical Str. 1/4′ Tube X 3/8′ M

Description

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.

Specifications

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.

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.

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.
