Swagelok 6LV-12-VCR-3S-12TB7 VCR Face Seal Fitting

Swagelok 6LV-12-VCR-3S-12TB7 is a VCR metal gasket face-seal gland from Swagelok’s VCR fittings family. The part is a short-gland variant (3S) with a 3/4 in connection and 12TB7 configuration, crafted in 316L VAR stainless steel for corrosion resistance and high purity. It uses Swagelok's VCR metal gasket face-seal technology to create a leak-tight metal-to-metal seal when paired with compatible VCR bodies and gaskets, suitable for vacuum to positive-pressure service. Designed for tube butt-weld connections, the gland is intended for high-purity gas delivery, semiconductor processing, pharmaceutical manufacturing, and analytical instrumentation where cleanliness and leak integrity are critical. The 316L VAR material specification indicates a high-purity stainless steel manufactured via vacuum-arc remelting to minimize impurities. This ordering number identifies a specific combination of gland style (short), size (3/4 in), and tubing interface (TB7), enabling reliable replacement in Swagelok systems and compatibility with standard Swagelok VCR components.
