MDC’s Kwik-Flange™ ISO KF and Large-Flange™ ISO LF Reducing Tees are versatile modular “building-block” components designed for high vacuum system layout and expansion. Constructed from Type 304 stainless steel using drawn and welded vacuum tubing, these fittings enable reliable size transitions within vacuum piping networks. Their symmetric, nonrotatable geometry ensures easy alignment and assembly. Available in main flange sizes NW25 to NW160 (DN25–DN160), reducing tees allow vacuum line branching while adapting to a smaller secondary port, optimizing flow and system flexibility in confined or custom configurations.

Industry applications

MDC’s Reducing Tees are widely used in semiconductor processing, pharmaceutical production, aerospace, and scientific research environments requiring size-adaptable, leak-tight vacuum connections. Their design allows seamless branching and downsizing within vacuum networks, ideal for space-constrained or performance-optimized systems. These tees integrate easily with ISO KF and LF components, supporting efficient vacuum line transitions while maintaining high conductance and structural integrity. Whether used in UHV chambers, cleanroom tools, or analytical equipment, MDC reducing tees offer flexibility, reliability, and ease of integration, ensuring durable performance in critical vacuum environments.
