Swagelok SS-8-WVCR-6-DF Rotating Female Union

Swagelok SS-8-WVCR-6-DF is a 316 stainless steel welded VCR face-seal fitting in the 1/2 in size, featuring a rotating female union. The VCR (face-seal) connection uses a metal gasket to achieve a leak-tight seal between mating VCR components. Built with a welded body, this fitting delivers a compact, robust connection suited to tight installations and demanding service. The rotating female union design allows alignment during assembly, reducing torque on adjacent components while maintaining a secure seal when paired with a Swagelok VCR male fitting and standard tubing runs. Crafted from 316 stainless steel for corrosion resistance in challenging chemical or sterile environments, it is commonly used in process gas lines, sampling systems, or instrumentation runs where reliable metal-to-metal sealing is required on 1/2-inch tubing connections.
