This is a pair of hinged vacuum sealing assemblies with flange support for 5" vacuum tube furnace to seal both ends of OD 130 mm( 5") tube without any welding and gluing.SPECIFICATIONS Features Seal the tube by tightening the screws on the flange without any welding or gluing. Excellent for any type of tubing: ceramic, glass, quartz, and steel pipe. Installation requires drilling holes in the furnace casing to mount the flange support. Made of Stainless Steel (SS304) with high-temperature silicon O-rings on each flange. Delicate metal support allows for both vertical and horizontal adjustment The openable flange is designed for sample easily loading/unloading. Descriptions The left end comes with a hinged flange with a barbed valve, 1/4" feedthrough and pressure gauge. Mechanical Pressure Gauge is available as an alternative to regular gauge. The right end comes with a hinged flange with a barbed valve and a KF25 vacuum port. KFD25 angle valve may be required for connecting the vacuum port to a vacuum pump. Vacuum level 10E-2 torr by a mechanical pump 10E-5 torr by a small turbopump and 10-6 torr by hi-speed turbopump Application Note Place the o-ring on the notch of the hinged flange. A tube block is required behind each flange to avoid the silicone O-rings melting. In the parts diagram on the left, the dia# is 100 for this product. Tube block is available in related products below. Please do not over-tighten the three hex screws on the flanges to avoid overpressure incidents. The recommended torque is 35~40 inch-lbs.
