The KM77 features an all stainless version of our Rex® regulator, as well as a stainless sideblock, helmet ring, bent tube, handle, and other key components. The Rex® Quad Valve® Exhaust System is standard on this helmet.
The removable regulator pod allows the Kirby Morgan® 77 to be fitted with the Kirby Morgan SuperFlow® 350 regulator or the stainless steel 455 Balanced Regulator. The pod will make it possible to customize the helmet with the regulator you want as job requirements change.The advantages of this stainless steel helmet include the following:
• Rugged helmet shell and other components • Elimination of threaded inserts for securing port retainer to helmet shell • No refinishing required if the surface is scratched or gouged
