Swagelok 6LV-8-VCR-3-4TB7 VCR Tube Fitting 316L

Swagelok 6LV-8-VCR-3S-4TB7 is a 316L VAR stainless steel VCR metal gasket face-seal fitting with a short-tube butt weld gland, designed to connect a 1/2 in. VCR port to a 1/4 in. tubing line using a 0.035 in. nominal wall (TBW). The 3S designation indicates a short gland, and the 4TB7 suffix denotes the 0.035 in. TBW tube-wall configuration, with an external length of 0.75 in. (19.1 mm). Constructed from 316L VAR stainless steel, this part provides robust corrosion resistance for demanding service, and it employs Swagelok’s VCR metal gasket face-seal technology to deliver a leak-tight, reusable connection when installed per Swagelok guidelines. The fitting features a 1/2 in. VCR size and a 1/4 in. tubing interface, making it a compact option for tight spaces in vacuum and high-purity process lines where a short, welded-tube gland is advantageous.
