MDC’s Straight Tube Nipples are high-precision, modular fittings designed for ISO KF and ISO LF vacuum systems. As part of the Kwik-Flange™ and Large-Flange™ product lines, these building-block components are engineered for use in the construction, expansion, or maintenance of high vacuum assemblies. Each nipple is fabricated from drawn and welded 304 stainless steel tubing, ensuring durability, corrosion resistance, and leak-tight integrity under extreme vacuum conditions.

Available in a broad range of sizes from NW16 to NW500, these nipples feature symmetric, nonrotatable geometries for consistent alignment and assembly. With a high vacuum rating of 1x10⁻⁸ Torr (1.3x10⁻⁶ Pa) and temperature resistance up to 200°C, they are ideal for demanding environments. The ISO-compatible design ensures seamless integration with both KF and LF flanges, simplifying system design and standardization.

Industry Applications

MDC’s ISO KF and LF Straight Tube Nipples are widely used in vacuum processing equipment, semiconductor fabrication tools, thin-film deposition systems, and research vacuum chambers. Their robust construction and vacuum compatibility make them ideal for pumping lines, chamber connections, and custom manifold configurations. Whether in UHV labs, plasma processing, or aerospace testing, MDC’s welded nipples provide a critical link for vacuum integrity, offering consistent performance and easy integration across standard ISO flange systems.
