Swagelok B-600-6-4 Reducing Union, 3/8 in. x 1/4 in. Tube OD, Brass

Separate air lines with unequal outside diameters call for a joint that receives both of your tube sizes. The Swagelok B-600-6-4 reducing union accepts 3/8 in. and 1/4 in. tube OD directly. This union fitting connects the unequal tube sizes in a Brass body.

You insert each tube into its corresponding compression fitting end. Match your larger run to the larger opening and the smaller line to the smaller opening. The body material puts this connection among brass fittings for assemblies specifying that material at the tube joint.

For a Gulf Coast instrument air layout, you can choose this part with your instrumentation fittings where the tubing specification changes between connected runs. Baton Rouge stock at Collins-Oliver is available for same-day pickup and nationwide shipping. Call for a quote on the union your drawing requires.
