Model J Regulator

Shipping calculated at checkout.

The Model J regulator/vaporizer delivers reliable performance and pressure output consistency. Its reliability, especially with questionable fuel quality, has made it an industry standard for many years.

Two vapor outlet pressures are available. The standard JB blue provides -1.5” w.c. (0.37 kPa). The optional JO provides -0.5” w.c. (0.12 kPa). The port size and mounting pad locations are identical to the Cobra regulator and include a primary pressure test port and “left” or “right” fuel outlets.
