Brass Conical Str. 3/8'tube X 1/8' M

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. It’s 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.

AirCraft tube fittings are built for practical pneumatic installations. This straight connector gives you a tidy transition from 3/8" tubing to a 1/8" male-thread port with a compact, workshop-ready finish.
