Stainless Steel Swagelok Tube Fitting, Male Connector, 1/4 in. Tube OD x 1/2 in. Male NPT

Step a small tube up to a big port in one fitting. The Swagelok SS-400-1-8 carries 1/4 in. tube straight into a 1/2 in. male NPT connection, so you land on an oversized process port without stacking a bushing and a reducer behind it.

Every extra threaded joint you stack is another leak path and another thing to chase during a hydro test. This connector removes two of them. The tube end is a genuine gaugeable Swagelok two-ferrule connection in 316 stainless steel, and the pipe thread is cut on the same body.

Instrument techs pull this exact combination for pressure taps, drain legs and transmitter hookups on vessels drilled for larger pipe. Collins-Oliver keeps it in Baton Rouge for same-day pickup. Call (800) 247-5756 or request a quote.
