The Silicon Double Seal purging system has been designed to further reduce both inert gas use and purging time. These systems, use silicon discs to form an airtight seal, reducing purge times, and gas usage for maximum efficiency. The Gas Finger system is designed for small pipes and tubes from 16 – 38mm i/d.
- Typical purge times of less than 2 minutes (e.g. an 8” Pipe will purge to below 0.01% Oxygen in less than 2 minutes)
- High-quality silicon sealing disks that prevent them from tilting or falling over inside the pipe
- Guaranteed gas-tight seal
- UV and temperature resistance up to 330ºc continuously or 450ºc for short periods
- Suitable for purging pipes, elbows and fittings
- The silicon seal units can be separated and used as a gas finger and pipe stopper respectively
