Because of the outside flange dimension, FireLock Flange adapters should not be used
on FireLock fittings. When wafer or lug-type valves are used adjoining a Victaulic fitting,
check disc dimensions to assure proper clearance.
FireLock Flange adapters should not be used as anchor points for tie-rods across
nonrestrained joints. Mating rubber faced flanges, valves, etc., require the use of a
FireLock Flange washer.
FireLock Flange gaskets must always be assembled with the color coded lip on the pipe
and the other lip facing the mating flange.
