The Flex Purge is a double seal purging system that works in the ranges from 25mm to 150mm for purging of pipes and tubes with inert gas before welding.

Flex Purge is easy to pull through pipes and bends without tilting. The design of the system also guarantees that at least one disc holds tight and this will reduce both purging time and inert gas use.
Going from the welding of one pipe dimension to another, you simply change the sealing discs on the basic unit.

The Silicone Discs are temperature resistant up to 320°C
