Swagelok 6LV-8-VCR-3-8TB7 VCR Fitting Long Tube Butt Weld Gland

Swagelok 6LV-8-VCR-3-8TB7 is a 316L VAR stainless steel VCR long-tube butt-weld gland that connects a 1/2 in. VCR connection to a 3/8 in. tube butt-weld joint, designed for high-purity, high-vacuum service. As a long-gland member of Swagelok’s VCR metal gasket face-seal family, it provides extended engagement for secure, leak-tight connections in environments that undergo thermal cycling. The body material is 316L VAR stainless steel, suitable for cleanroom and ultra-high-purity applications, and it accepts Swagelok VCR gasket-face-seal components to form a robust metal-to-metal seal. This gland is intended for use in high-purity gas delivery, vacuum systems, and analytical instrumentation where reliable, repeatable sealing is essential, including semiconductor processing and other precision fluid-handling setups. The tube-side connection is a butt-weld joint, enabling a welded interface to the tubing for compact, integrated assemblies, while the VCR face-seal gland end provides Swagelok’s proven gasket-based sealing technology.
