Water Cold Sealing Flang for 3.5" (89 mm) dia.Tube - EQ-FG-89WC

This is a pair of sealing flange with the water cooling jacket valve for OD 3.5" (89 mm diameter)  processing tube. If you cannot use a ceramic block in two ends of tube, you must use the water cooling jacket to keep flange cool (otherwise silicone o-ring may get damage)

SPECIFICATIONS

Features	Made of Stainless Steel with double high-temperature silicone O-rings on the flange.   Stainless steel needle valve with 1/4" barbed fitting. 12mm Push to Connect port for water tube.     The assembly kit will seal one end of 89-91 mm ( 3.5") diameter ceramic and quartz tube. Vacuum meter is installed in one side of flange. You may choose left side, right side or a full set of the flange at product option bar Note:  You may order Digital Temperature Controlled Recirculating Water Chiller with 16L / min Flow, to cool the flange and save water.

Vacuum level	10E-2 torr by a mechanical pump 10E-5 torr by a small turbopump and 10-6 torr by hi-speed turbopump
Warming	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.
Optional	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 order a flowmeter to control gas flowing You may order flange support to avoid tube turning ( pic below right)
Application Notes	Max. furnace working temperature is 1100ºC without thermal block  If furnace working temperature > 1100ºC, suggest you use a thermal block  Please always use a recirculating water chiller (see related product below) to save water and protect
