Designed for MTI GSL1600-80X tube furnace. Excellent for any type of tubing: ceramic, glass, quartz and steel pipe. The assembly kit will seal 88 - 89 mm diameter of ceramic tube. Vaccum level 10E-2 torr by a mechanical pump 10E-4 torr by a small turbopump and 10-6 torr by hi-speed turbopump Optional Parts Please click here to order digital vacuum gauge for precision vacuum control upto 10 -4 torr You can choose various end of fitting as options ( click here to order separately ) Please click here to order digital vacuum gauge for precision vacuum control up to 10 -4 torr Warning Must put a refractory tube block in front of the flange (see picture below) to avoid heat radiation melt silicone O-ring. You order a ceramic block in related products. Please do not over tighten the three hex screws on the flanges to avoid overpressure incidents. The recommended torque is 35~40 inch-lbs. For liability considerations, MTI does not recommend or endorse the use of any toxic, flammable or corrosive gases with our flange assemblies. Please contact us with any concerns.

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.

Seal the tube by tightening the screws on the flange without any welding and glue. 1\/4\" in diameter vacuum sealing assembly will connect with a 1\/4\" rubber hose. Designed for MTI OTF-1200X Desktop Quartz Tube Furnace. Excellent for any type of tubing: ceramic, glass, quartz, and steel pipe. Options Please click here to order a digital vacuum gauge for precision vacuum control up to 10 -4 torr For CVD application, please choose anti-corrosive vacuum gauge ( click pic below left 2 ) You can choose the various end of fitting as options ( click here to order separately ) You may click here to order a flowmeter to control gas flowing You may order flange support to avoid tube turning ( pic below right) Notes Must put a refractory tube block in front of the flange (see picture below) to avoid heat radiation melting silicone O-ring. You can order a ceramic block in related products. Please do not over-tighten the three hex screws on the flanges to avoid overpressure incidents. The recommended torque is 35~40 inch-lbs. For liability considerations, MTI does not recommend or endorse the use of any toxic, flammable, or corrosive gasses with our flange assemblies.

SPECIFICATIONS Features Seal tube by tightening 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 on 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. Designed for MTI Dual Zone Split Tube Furnace with Vacuum Flanges \u0026amp; 4\" Quartz Tube - OTF-1200X-4-II. 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 alterlative of regular gauge. The right end comes with a hinged flange with a barbed valve and KF25 vacuum port. KFD25 angle valve may require for connecting the vacuum port to a vacuum pump. Please choose the KF25 angle valve at the related product below. 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 80 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.

Made of Stainless Steel ( SS304) with double high-temperature silicon O-rings on each flange. Vacuum level: 10E-5 torr by molecular pump and 10E-2 torr by mechanical pump Descriptions 2” flange with various optional (please choose from Product Options) One end of the flange has a barbed needle valve,1\/4\" feedthrough for thermocouple inserted and 1\/8 NPS valve with installed Mechanical Pressure Gauge. (if you need  Compact Digital Vacuum Gauge , please choose from product option at extra cost . If you don't need vacuum gauge, please instruct us when you order, we can take it off, but no price deduction ) Another end of the flange has a KF25 port with barbed needle valve. You may need KFD25 angle valve before connecting the vacuum port to vacuum pump. Please choose the KF25 angle valve at related product below. Seal tube by tightening screws on the flange without any welding and glue. 1\/4\" in diameter vacuum sealing assembly will connect with 1\/4\" rubber hose. Designed for MTI OTF-1200Desktop Quartz Tube Furnace. Excellent for any type of tubing: ceramic, glass, quartz and steel pipe. Warning Must put a refractory tube block in front of the flange (see picture below) to avoid heat radiation melt silicone O-ring. You order a ceramic block in related products. Please do not over tighten the three hex screws on the flanges to avoid overpressure incidents. The recommended torque is 35~40 inch-lbs.

Made of Stainless Steel with double high-temperature silicon O-rings on each flange. On one end the flange has a vacuum meter with a valve attached, and on the other end has the only valve. Seal tube by tightening screws on the flange without any welding and glue. 1\/4\" hose connector in both of ends. 1\/4\" in diameter vacuum sealing assembly will connect with 1\/4\" rubber hose. Excellent for any type of tubing: ceramic, mullite, glass, quartz and steel pipe. The assembly kit will seal 82 - 84 mm diameter of Alumina or Mullite tube. Package included One flange with gauge and valve, one flange with valve, two steel sealing rings, four high-temperature silicone O-rings ( 300 o C Max.), and six screws Vacuum level: 10E-2 torr by a mechanical pump 10E-5 torr by a small turbopump and 10-6 torr by hi-speed turbopump Warning Must put a refractory tube block in front of the flange (see picture below) to avoid heat radiation melt silicone O-ring. You order a ceramic block in related products. Please do not over tighten the three hex screws on the flanges to avoid overpressure incidents. The recommended torque is 35~40 inch-lbs.
