Swagelok Bulkhead Reducing Union, 1/4 in. x 1/8 in. Tube OD, 316 Stainless Steel. Swagelok Part Number: SS-400-61-2 This Swagelok® bulkhead reducing union connects 1/4 inch to 1/8 inch stainless steel tubing through a bulkhead. The fitting is made of 316 stainless steel. Nuts and ferrule set are included. Nut threads are silver plated to prevent galling and seizing of the fitting when tightened. Bulkhead connectors are used when it is necessary to go through a plate, chassis, cabinet or chamber. A bulkhead generally separates a closed space, which may have different environmental characteristics (i.e., a vacuum chamber), from open space, typically ambient atmosphere. Swagelok bulkhead fittings are available for same-size tubing (bulkhead unions), to reduce one size tubing to another (bulkhead reducing unions), or to adapt tubing to pipe thread (bulkhead male or female NPT). These industry standard Swagelok compression-type fittings and components are precision manufactured and offer a gas-tight, metal-on-metal seal. They are available in standard fractional tubing sizes for making up stainless steel tubing. Polished surface finishes and high purity materials virtually eliminate these fittings as a source of system contamination. They can be used for any fluid flow application and provide leak-tight service from vacuum to positive pressure. These fittings offer consistent gaugeability upon initial installation and are easy to disconnect and retighten reliably. The two-ferrule design of these fittings are easy to install and no torque is transmitted to the tubing during installation. The two ferrules separate sealing and tube gripping functions; each ferrule is optimized for its function. Available Swagelok gap inspection gauges assure sufficient pull-up upon initial installation. Swagelok tube fitting ends are rated to the working pressure of tubing as listed in the Swagelok Tubing Data PDF, available here for download. Fitting specifications are shown in the second image.
