Product Description

MATHESON made in the USA



A high-purity regulator designed for analytical applications using corrosive, toxic, or pyrophoric gases.


• Supply of corrosive, toxic, or pyrophoric gases where a positive closure of the regulator is desired.
• Supply of corrosive/toxic gases to semiconductor manufacturing processes.

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.

Looking for something a little bit different? Different inlet or outlet fitting or remove the outlet valve? Check out our Modified 3610A Pressure Regulator.

• High-purity 316L stainless steel barstock body
• High-purity 316 stainless steel diaphragm
• Metal to metal seals minimize diffusion of contaminants
• 2” inlet and delivery pressure gauges
• Tied seat design helps to ensure regulator closure
• Equipped with outlet diaphragm valve
• 1/4” compression tube outlet connection
• Porous metal filter protects seat from contamination
• Panel mountable from rear with two threaded holes

No Lube
A small amount of polychlorotrifluoroethylene is added to the threads to facilitate assembly. For ECD, MS or AED applications where method detection limits are sub-ppm, it is recommended to use a No Lube (-NL) model.

Cross Purge
• Eliminates the escape of hazardous gases when changing cylinders
• Reduces danger of contamination from atmospheric moisture and oxygen
• Minimizes the amount of gas lost during cylinder changes
• 4360 Series Quarter-Turn Diaphragm Valves used throughout
• All stainless steel construction (4774 Series Cross Purge)
