Reducing Nipple for Fire Suppression Systems

Aegis DROPSTER™
Drop Nipple

The Aegis Dropster™ Non-Adjustable Drop Nipple is a highly engineered reducing nipple made from high strength carbon steel conforming to ASTM standards. The one inch (1”) male NPT or ISO threaded or plain inlet by half inch (½”) or three quarter inch (¾”) NPT sprinkler outlet by a standard or specified fitting length eliminates threaded reducing coupling and labor make-up costs. A “double end” model with a half inch (½”) or three quarter inch (¾”) NPT sprinkler outlet on both ends for field cutting, threading, and installation is available.

Any Aegis Dropster™ model may be field cut down, threaded, and installed. Designed for use in wet or dry systems in accordance with NFPA Standards 13, 13R, & 13D, and is rated for use at a maximum pressure and temperature of 300 PSI and 300°F, respectively. UL & ULC Listed in accordance to UL 1474 5th Edition, UL213 4th Edition, UL213B Issue 5 and FM Approved in accordance to FM Class 1631. The inlet threads conform to ANSI B1.20.1 NPT or ISO 7-1. The outlet threads conform to ANSI B1.20.1 NPT or better. Each unit has been pressure tested for material integrity prior to shipment.
