Swagelok 6LV-4-VCR-3-4TB3P is a high-performance 316L VAR VCR fitting designed as a long tube butt weld gland. This component is engineered for metal gasket face seal systems in critical environments, including high-purity, high-vacuum, and thermal cycling applications. The gland features an extended 0.38 in. (9.6 mm) length to facilitate easier installation and engagement in complex system layouts.

Manufactured from 316L VAR (Vacuum Arc Remelt) stainless steel and electropolished to a high-quality finish, this gland ensures superior material purity and corrosion resistance. It is processed according to Swagelok Ultrahigh-Purity Process Specification (SC-01), making it suitable for semiconductor and other ultrahigh-purity gas delivery systems.
