Swagelok 6LV-4-VCR-3S-4TB3 Tube Butt Weld Fitting

Swagelok 6LV-4-VCR-3S-4TB3 is a 316L VAR stainless steel VCR metal-gasket face-seal fitting in a short-gland configuration, designed to connect 1/4 in tubing to Swagelok VCR components with a butt-weld (TBW) end. The assembly pairs a 1/4 in VCR end with a 1/4 in TBW tubing end for tubes with a nominal wall thickness of 0.035 in, providing a compact 0.38 in (9.6 mm) extension from the mounting surface. Built as a short-gland VCR fitting, it delivers a leak-tight metal-to-metal seal suitable for high-purity, high-integrity fluid systems. Crafted from 316L VAR stainless steel, this Swagelok fitting offers strong corrosion resistance in demanding environments and is suited for cleanroom–grade process lines in pharmaceutical, semiconductor, and chemical processing where VCR connections are used.
