Type T208 to the Type T208M with two O-rings and a

machine screw.

• Rugged Construction—Heavy duty casings and internal

parts are designed to reduce vibration and shock and

give this regulator the ability to withstand up to 35 psig /

2.4 bar (with Nitrile (NBR) and Fluorocarbon (FKM)

diaphragms) and 10 psig / 0.69 bar (with Fluorinated

Ethylene Propylene (FEP) diaphragm) with no internal

parts damage.

• Simplicity—Direct-operated, straightforward stem

and lever design minimizes the number of parts while

providing excellent regulation of pressure.

• Sour Gas Service Capability—Available construction to

meet NACE MR0175-2002.
