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 ( picture 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. 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.
