Neoprene as needed for some gases.
If your application demands a different material, please contact Alicat.
1. In addition to all non-corrosive gases, PC & PCR controllers are configured to operate with the following
aggressive gases: Ammonia, Hydrogen Sulfide, Nitric Oxide, Nitrogen Dioxide, Nitrogen Triflouride, Propylene.
The following gases are available upon request: Refrigerant gases to 100% (Refrigerant gases my require
custom seals, consult Alicat.) Other gases to 1000 ppm in an inert carrier. If your application requires another gas
or gas mixture, please contact Alicat. PCS and PCRS devices may be used with chemically compatible liquids.
Please contact Alicat for technical assistance if your application involves fluids.
