MDC’s Vacuum Tees are precision-engineered fittings designed to join CF flange connections of varying sizes in a T-shaped configuration, ideal for branching vacuum lines or integrating diagnostic and pumping ports. Fabricated from 304 stainless steel using drawn and welded vacuum tubing, these tees ensure excellent durability, structural integrity, and ultra-high vacuum (UHV) compatibility. Each axis of the tee features one rotatable CF flange, allowing for easier alignment and flexible system design during assembly.

Rated for UHV service to 1x10⁻¹³ Torr and high-temperature use up to 450°C (842°F), these fittings are well-suited for rigorous scientific, industrial, and research environments. The standard matte finish enhances vacuum cleanliness by minimizing surface outgassing.

Industry Applications

MDC’s Vacuum Tees are used across semiconductor fabrication, beamline design, thin film deposition, and analytical systems requiring three-way vacuum routing. Their rotatable flange design makes them ideal for systems where exact alignment is challenging or where modular upgrades are common. They are also trusted in surface science research, space simulation chambers, and cryogenic test setups, offering durable, leak-tight branching connections with full UHV compatibility
