    • 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 the both of ends.
    • 1/4" in diameter vacuum sealing assembly will connect with 1/4" rubber hose.
    • Designed for MTI OTF-1200X-80 tube furnace.
    • Excellent for any type of tubing: ceramic, glass, quartz and steel pipe.
    • The assembly kit will seal 80 - 82 mm diameter (3-1/8 ~~ 3-1/4" Dia) of the quartz tube.
Package included  One flange with gauge and valve, one flange with valve, two steel sealing rings, four high-temperature silicone O-rings  ( 300oC 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
How to seal a quartz tube using the assembly, please follow the photos below:
  
 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 gasses with our flange assemblies. Please contact us with any concerns.
