Aegis ADJUSTER™
Adjustable Drop Nipple
The Aegis Adjuster™ Adjustable Drop Nipple consists of high strength carbon steel casings and ethylene propylene diene monomer (EPDM) O-ring seals. The outer case, with a one inch (1”) male or female NPT inlet, and the inner case, with a half inch (½”) or three quarter inch (¾”) NPT sprinkler outlet, adjusts in or out over a specified range with the use of two (2) O-ring seals and screw type threads to permit, without re-cutting, the adjustment of the distance of the sprinkler from the sprinkler system branch line.
Once in its final adjusted position, the Adjuster™ ADN will not extend as a result of system vibrations or pressure surges. 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 Listed in accordance to UL 1474 and FM Approved in accordance to FM Class 1631. The inlet and outlet threads conform to ANSI B1.20.1. Each unit has been pressure tested for O-ring integrity prior to shipment.
