High airtight screw connection fittings for piping using the principle of plastic deformation at the joints, suitable for a wide range of pressures.
High airtightness is achieved by using the principle of plastic deformation at the joints. A thin metal sheet is sandwiched between flanges with a flat flange and protrusions. 【Features】 ■ Easy assembly and disassembly ■ Low design tightening pressure ■ No torsional torque is applied to the piping ■ Allowable leakage rate of 1×10⁻¹⁰ Pa·m³/sec or less ■ Metal sealing cup ■ Temperature: -270 to 700℃ *For more details, please download the PDF or contact us.
