Swagelok B-400-7-8 Female Connector, 1/4 in. Tube OD x 1/2 in. Female NPT, Brass

Enlarging the threaded instrument connection need not enlarge the pilot tubing you bring to it. The Swagelok B-400-7-8 female connector takes your 1/4 in. tube OD to a 1/2 in. Female NPT connection. You retain the smaller tube at the larger nominal threaded hookup.

You seat your tubing in the Swagelok compression fitting end of the Brass body. The female end receives the mating male thread, putting this part among threaded connectors for tube-to-instrument joints. Specify it where your assembly calls for brass fittings.

In a Gulf Coast instrument air assembly, you can select this size combination from your instrumentation fittings list to connect pilot tubing at the instrument. Collins-Oliver stocks it in Baton Rouge, offering same-day pickup and nationwide shipping. Ask the counter to quote this part for your assembly.
