MDC’s ISO LF Clamp-Style Half Nipples are precision-manufactured components designed for large-scale high vacuum systems. As part of the Large-Flange™ (ISO LF) fitting series, they serve as reliable building-block elements, supporting the modular design and expansion of custom vacuum networks. Each nipple is fabricated from drawn and welded 304 stainless steel tubing, offering superior mechanical strength, thermal tolerance, and corrosion resistance.

These components are rated to 1x10⁻⁸ Torr (1.3x10⁻⁶ Pa) and temperature-rated to 200°C, making them ideal for demanding vacuum environments. Sizes range from NW63 to NW500, accommodating a wide variety of vacuum chamber and piping requirements. The symmetric, nonrotatable geometry enhances mechanical alignment, while the standard matte finish promotes cleanliness. Claw clamps are required for secure mounting—refer to flange size specifications for compatibility.

Industry Applications

MDC’s ISO LF Half Nipples are widely used in industrial and research-grade vacuum systems, including vacuum metallurgy, coating systems, particle accelerators, plasma processing, and fusion experiments. Their robust construction and broad size range allow them to serve as core components in UHV chambers, vacuum piping networks, and high-throughput process systems. Whether used in semiconductor tools, aerospace test rigs, or scientific facilities, these fittings deliver consistent vacuum performance, mechanical reliability, and flexible modularity.
