Unlike other infiltration rings on the market, the AMS infiltration rings are constructed of rolled 16 gauge mild steel with gold zinc plating – instead of being made of galvanized steel. They are also plated with corrosion resistant gold zinc plating. This substantially increases the durability of each unit.
The units come in two sizes, 6″ ID 12″ OD and 12″ ID 24″ OD
A user manual and correlation chart is included with each unit.
