Notes
  • Must put a refractory tube block in front of the flange (see picture below) to avoid heat radiation melting silicone O-ring. You can 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.
