Model SSG9048

Acetylene, Atomic Adsorption Grade Regulators

This regulator is specifically designed for use with Atomic Absorption or Technical Grades of Acetylene. Although similar to our Model SSE regulator, its delivery pressure gauge features a red line warning above 15 psig to indicate unsafe delivery pressure for acetylene.



Regulator for Specific Application SG6545 Flash ArrestorStandard Features
  • Limited Delivery Pressure Adjustment does not allow delivery pressure above 15 psig as recommended for Acetylene service.
  • Neoprene Diaphragm permits accurate delivery pressure settings.
  • Cartridge (Encapsulated) Seat Assembly provides for ease of maintenance and repair.
  • Filter in Seat Assembly traps foreign matter, extends regulator life and reduces maintenance.
  • Red-Lined" Delivery Pressure Gauge provides visual indication should delivery pressure exceed allowable withdrawal pressure of 15 psig.
  • Outlet Metering Valve provides flow control.
Optional Features
  • Acetylene Flash Arrestor prevents flashback into cylinder.
