{"product_id":"fl-84","title":"Vacuum Sealing Assembly for 84 mm dia Tube Furnace with Valve \/ Vacuum Meter - FL-84","description":"This is a pair of smart sealing assembly for tube vacuum furnace to tighten both ends of OD 84 mm tube without any welding and gluing. Made of Stainless Steel with double high-temperature silicon O-rings on each flange. On one end the flange has a vacuum meter with 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. Excellent for any type of tubing: ceramic, glass, quartz and steel pipe. The assembly kit will seal 84 - 86 mm diameter of MTI Alumina and Mullite tube as related product below. um level:  10-5 torr by the molecular pump and 10-2 torr by a mechanical pump 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 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.
