Vacuum Sealing Flange for 3" (76 mm) dia Tube Furnace with Valve / Vacuum Meter - FL76

This is a pair of smart sealing assemblies for a tube vacuum furnace to tighten both ends of OD 3" tube without any welding and gluing.

SPECIFICATIONS

Three types of Package optional
( choose from product option )		 For both sides: A pair of flanges with 4 high-temperature silicone O-rings(300°C Max.) and 1 mechanical gauge 
For left side: Left side flange with 2 high-temperature silicone O-rings(300°C Max.) and 1 mechanical gauge 
For right side: Right side flange with 2 high-temperature silicone O-rings(300°C Max.)
Features
  • Made of Stainless Steel with double high-temperature silicon O-rings on each flange.
  • One end flange has a vacuum meter with a valve, and another end has a valve.
  • 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-1200X3 3" Quartz Tube Furnace.
  • Excellent for any type of tubing: ceramic, glass, quartz, and steel pipe.
Vacuum Level
  • 10E-2 torr by a mechanical pump
  • 10E-5 torr by a small turbopump and 
  • 10-6 torr by hi-speed turbopump



Optional Parts
  • Please click here to order a digital vacuum gauge for vacuum control up to 10-4 torr
  • For CVD application, please choose anti-corrosive vacuum gauge ( click picture 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)
    •                 


Warning
  • Must put a refractory tube block in front of the flange ( see picture below ) to avoid heat radiation melt silicone O-ring. Please click the picture below-center to order the block.
  • 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.
