Purge Flex, manufactured by WELD-TECH, is a double seal purging system that works in the ranges from 25mm to 320mm.

Purge Flex is easy to pull through pipes and bends without tilting. The design of the system also guarantee that at least one disc holds tight and this will reduce both purging time and inert gas use. Typical purge time of less than 2 minutes (for example an 8” pipe will purge to below 0,01% Oxygen in less than 2 minutes).

Basic units are available in 3 lenghts, 120 mm, 150 mm and 200 mm. Each basic unit will fit all sizes of the sealing discs. The Silicone Discs is temperature resistant up to 320°C.
