The Impco Cobra regulator delivers superior performance and excellent pressure output consistency. Cobra offers greater service life than model J regulators and is ideal in for applications with controlled emissions. Its primary pin design and fluorosilicone diaphragm offer superior chemical resistance, resistance to over pressurization, and cold weather operation. Use of standard blue spring provides -1.5wc (0.37 kPa). You can use Cobra in place of a model J but you shouldn't use a model J in the place of a Cobra.
Vertical mounting is recommended.
