Models AGR3800, AGR3810

Ultra High Purity, Back Entry Regulators

Line Regulator Model AGR with Male ConnectorThe AGR3800 and AGR3810 Models are machined from bar stock and designed for use with ultra high purity gases in line applications at inlet pressures up to 3000 psig. They feature a back entry inlet port and threaded mounting holes providing flexibility with panel mounting configurations. The back port design allows front panel mounting of the regulator while concealing the inlet piping behind the panel.

These regulators are specially suited for point-of-use gas delivery systems requiring high leak integrity and guaranteed gas purity levels. Model AGR3800 is for non-corrosive gases; Model AGR3810 is suitable for use with most corrosive gases.

These back entry line regulators are utilized in the design of our P series panels.

Line RegulatorStandard Features
  • Porting Design permits inlet piping to be installed in back (rear) of regulator body.
  • Threaded Holes in Rear of Regulator permit front panel mounting.
  • Metal to Metal Diaphragm Seals assure maximum diffusion resistance.
  • Metal to Metal Diaphragm to Body Seal (without back-up o-ring) assures maximum diffusion resistance.
  • Filter traps foreign matter, extends regulator life and reduces maintenance.
Optional Features
  • Mounting Ring permits regulator to be rear panel mounted
  • Compression Fittings installed in inlet and outlet ports allow connection to 1⁄4" tubing.
  • Internal (Inboard) Helium Leak Test and Test Report certifies leak rate of less than 2 x 10–8 sccs air equivalent.
  • External (Outboard) Helium Leak Test and Test Report certifies leak rate of less than 5 x 10–7 sccs air equivalent.
