Furon® Dual Containment Fittings provide an extra level of safety in critical applications, transforming standard Flare Grip fittings to PFA over PFA dual containment. This ensures true dual containment throughout the chemical delivery system. The Dual Containment Fitting can mate up with chemical delivery systems, wet tools, valve boxes, individual components and drain lines. Furon Dual Containment Fittings are available in three designs: Flare Fittings, Flare Fitting Rear Seal Bulkhead and Flare Fitting Front Seal Bulkhead. The Front Seal version provides complete dual containment to the face of the bulkhead without requiring access to process tool internal components. The Rear Seal version is used primarily in applications requiring sealing on the internal surface of the containment area-such as a process tool cabinet.
