With long production experience in pumps, gears, compressors, seals and gaskets, Shuiben Electrical Machinery Co., Ltd. is a provincial professional metal seal manufacturer integrating design, wholesaler, production, sales and service together. We have passed the ISO9001: 2000 International Quality Certification, obtaining production license of national industrial products. Our customized metal seals are measured by authorities, reaching industrial standards.

The TVU-FV Series are viewing windows with a wide field of view. They enable observations of ultra-high vacuums in vacuum containers, from the atmosphere side. Their connecting flanges are knife-edge metal-seal bakeable types for vacuum systems.Windows are thin, providing wide field of view. Glass has high transparency rate in visible spectrum. Support bake-out at temperatures up to 420oC. Can be used from atmospheric pressure to ultra-high vacuums. Assured joint integrity first time - every time. The gasket forces and seal diameter are minimal, meaning that the load capacity of components is maximised. Leak-free connections – gas-tight metal-to-metal seal. The proven reliability of the pressure-energised bore seal makes Techlok connectors compact and up to 75% lighter than comparably rated flanges. The lack of a conventional flange gasket gives a gas-tight metal-to-metal seal. All sealrings meet NACE hardness limits.

Run 22 pounds of boost for seven miles, pumping out 275 hp and that old head gasket will surrender to the blowtorch of combustion. The hot gases will find the weakspot and cut the head and cylinder quicker than an ironworker can cut a structural beam. Totally new in concept, male/female ferrules use an "omega" designed metal to metal seal which has sealing surfaces both in recess protecting against damage. EXCEL-A-TEC's patented, aseptic, high pressure, high vacuum, and self aligning fitting is designed to eliminate the need for steam-seal fittings to achieve asepsis. It meets 3-A standards. Made of quality stainless steel, these patented fittings are available in sizes 1" to 3" and are competitively priced. Metal seals make flanges clean and enable low levels of outgas, ideal for ultra-high vacuums. Edges have original ULVAC long-life design that can withstand repeated connections.
