The C-CB-30177 COBRA Regulator / Converter / Vaporizer is an upgrade to the IMPCO model "J". It incorporates an improved primary seat and orifice that reduces the likelihood of failure due to freezing and contamination, the number one cause of the model "J" failure. The C-CB-30177 also includes a Flourosilicone secondary diaphragm that is more resistant to the heavy oils produced by heating LPG. Part number C-CB-30177 operates on the same principle as a model "J" with a primary pressure of 1.5 P.S.I., and a secondary pressure of -1.5" W.C. C-CB-30177 may be used to replace the model "J" in any application. Repair kits RK-COBRA or C-RK-COBRA are available for servicing.
