FM - Design Criteria
• Refer to Table A for Model, Nominal Assembly
Length, and Sprinkler Reducer combinations.
• Wet-pipe systems only.
• Maximum service pressure of 12 bar.
• Pendent sprinklers with a maximum K80 (K5.6) for
1/2 inch NPT or maximum K115 (K8.0) for 3/4 inch
NPT.
• Maximum ambient temperature of 107°C for Model
YB25 and YB28.
• These connections are designed for use in ceilings
with grids that meet ASTM C 635 (Standard Specifi-
cation for the Manufacture, Performance, and Test-
ing of Metal Suspension Systems for Acoustical Tile
and Lay-in Panel Ceilings) and ASTM C 636 (Stan-
dard Practice for Installation of Metal Ceiling Sus-
pension Systems for Acoustical Tile and Lay-in
Panels) referenced by IBC. The three structural clas-
sifications are the following: Intermediate-Duty Sys-
tems and Heavy-Duty Systems. These connections
have been approved for use in all Intermediate-Duty
and Heavy-Duty structural classifications.
• Minimum bend radius of 150 mm for Model YB28 or
200 mm for Model YB25.
• FM Friction Loss for YB25 and YB28:

UL - Design Criteria
• Refer to Table A for Model, Nominal Assembly
Length, and Sprinkler Reducer combinations.
• Wet-pipe systems only.
• The hose and ttings have limited exibility and are
intended for direct connection to sprinklers in accor-
dance with NFPA 13, 13D, or 13R.
• Maximum service pressure of 13 bar.
• Pendent sprinklers with a maximum K80 (K5.6) for
1/2 inch NPT or maximum K115 (K8.0) for 3/4 inch
NPT.
• Maximum ambient temperature of 107°C for Model
YB25 and YB28, or maximum ambient temperature
of 148°C for Model YN25.
• These connections are designed for use in ceilings
with grids that meet ASTM C 635 (Standard Specifi-
cation for the Manufacture, Performance, and Test-
ing of Metal Suspension Systems for Acoustical Tile
and Lay-in Panel Ceilings) and ASTM C 636 (Stan-
