STAINLESS STEEL DISC
A frangible stainless steel disc, Part No. 81-220299-000 (Figure 2-61 and Figure 2-62), is 

available to prevent the entry of particulate matter into a type S nozzle.

The type M multijet nozzle (Figure 2-64) is similar in design and operation to the type S nozzle, 

and is used for applications requiring higher flow rates than those attainable with the type S 

nozzle. Strainers are provided with nozzles having orifice code numbers from 4 to 5+. The 

nozzle body is longer than the type S body in order to accommodate the higher flow rates. The 

type M nozzle has a red painted cold-rolled steel body. The Type M multijet nozzles have a 

3/4 inch NPT inlet connection for attaching to the CO
