The WeldPurge Double Seal Gas Finger is a specialized purging system specifically designed for small pipes and tubes ranging from 16 – 38mm in diameter. Utilizing silicon discs to create an airtight seal, this system greatly reduces both the amount of inert gas needed and the purging time required. With typical purge times of less than 2 minutes, even an 8” pipe can be purged to below 0.01% Oxygen in a matter of minutes.

This system features high quality silicon sealing disks that keep them from tilting or falling over inside the pipe, ensuring a gas tight seal every time. It is also resistant to UV and temperature, able to withstand continuous use at 330ºc or short term use at 450ºc. It can be used to purge pipes, elbows, and fittings, and the silicon seal units can even be separated and used as a gas finger and pipe stopper.
