Cast Iron Soil Pipe & Fittings
Domestic vs Import
• CISPI is an exclusive and closed marketing association, whose

• The coils, fans and louvers in a HVAC system
that moves the air that we breathe
• The regulators and manifolds in a medical gas
system delivering life saving oxygen
• The steel pipe that delivers natural gas to heat
our buildings and hot water.

that would certainly meet any attempt to require
all of the above materials to meet the
