Product Description

MATHESON made in the USA



Corrosive service regulators constructed of Monel for superior corrosion resistance.


• Pressure regulation of acid forming halogen gases, such as hydrogen chloride, chlorine, hydrogen fluoride, hydrogen bromide, and silicon tetrafluoride
• Dispensing of corrosive calibration gases
• Research and development applications where a corrosion resistant regulator is required for either corrosive ambient conditions or corrosive gas service
• Applications requiring extended regulator lifespan in severe conditions

MATHESON strongly recommends the use of a cross-purge with any regulator put into highly corrosive or toxic gas service. You can easily add a cross-purge to this model regulator by selecting "Yes" for the Cross Purge option above.
