Merit Eliminator Adjustable Drop Nipples provide the user with the ability to adjust fire sprinkler assemblies (concealed, recessed, or pendent) to fit flush to the finished ceiling without having to cut a drop nipple or drain the system.
  • Available in two models, female or male thread inlet, with three standard lengths with adjustment up to 3" (7.62 cm)
  • UL Listed, FM Approved, and BSA-NYC Approved for installation to NFPA Bulletin 13 requirements. VdS Approved for the European market.
  • Cold formed from steel conforming to ASTM Grade.
  • Inner nipples employ two (2) “O-Rings” to provide added assurance of sealing. The “F” Model is designed to keep “O-Rings” from impinging upon the one inch (1") inlet threads when fully retracted.
  • The bore of the outer nipple is precision formed to a close tolerance while held to a microfinish of 50 to provide for positive sealing of the “O-Rings”.
  • Each unit is hydrostatically tested to insure “O-Ring” integrity prior to shipment.
  • Each unit is marked with a lot number to insure full traceability.
  • Qualifying tests on all models are performed at 1500 PSI, while the various models are rated for 300 PSI operation.
  • Threads are cut to be better than or equal to the requirements of ANSI B1.20.1, NPT or ISO-7-1 threads.
