General

Description

The TYCO Type SB Flush Deck Nozzles

are washdown nozzles for use on

United States Navy ships. They are

welded into position ﬂush with the

deck surface. The inlet to the nozzle is

sized for welding or brazing to 1/2 inch

(DN15) pipe.

The Flush Deck Nozzles have a Ball

that normally rests in the exit oriﬁce to

prevent debris from falling into it. When

water is ﬂowing, the Ball is lifted up and

remains centered by the combination

of the threaded insert and the inside

edges of the three webs. The sepa-

rable Truss Head Machine Screw and

Fender Washer supplied with the Type

SB Flush Deck Nozzles are used to

temporarily cover the nozzle when the

deck is being restored.

The Type SB Replacement Parts Kit

that includes a Web with Modified

Threaded Insert, Ball, Modiﬁed Insert,

Truss Head Machine Screw, and

Fender Washer is illustrated in Figure

2. A Threaded Insert Installation Tool is

also available.
