Swagelok SS-401-PC-2 Tube Fitting Reducing Connector

Swagelok SS-401-PC-2 is a stainless steel reducing port connector that provides a direct transition between two tube sizes in a Swagelok tubing system: 1/4 in. OD tubing on one end and 1/8 in. OD tubing on the other. Manufactured from 316 stainless steel, this PC (port connector) part sits in Swagelok’s catalog as a compact, single-piece reducer designed to maintain tight, consistent interfaces in corrosion‑resistant service. The -PC-2 suffix indicates the 1/4 in. to 1/8 in. size reduction, and the product is sold as a two-pack, making it convenient for installations or replacements requiring multiple connectors. In a stainless steel circuit, this reducing port connector enables a straightforward diameter step without adding separate adapters, helping to keep tubing runs simpler and neater. Because it uses a stainless steel construction, it is suitable for chemical compatibility in many process and instrumentation networks that specify 316-grade materials. Swagelok port connectors are designed to integrate with the broader line of Swagelok fittings, ensuring compatibility with other SS-401-series components and Swagelok tube fittings.
