* — the seal of the ГТ-701-M20 × 1.5 liner with a lug is provided by means of a copper gasket, ГТ-701-M27×2 and ГТ-702-M33×2 liner to the temperature of 350°C - sealed with a copper gasket or welding, at temperatures from 350 °C to 550 °C only by welding.

If it is necessary to seal the ГТ-701-M27×2 and ГТ-702-M33×2 liners to 350 °C only by welding (no gaskets are required), specify the temperature of 550 °C in the order.
