** = These are organic materials that will feed a fire if a leak occurs and an ignition source exists.
*** = Ammonia (wet) - Data to +100°F (+38°C) only (same materials as dry).
For pipe diameters over 24” or ANSI Class pressure ratings of 600# or greater, use G-10 sleeves and G-10 washers
where temperatures and other conditions permit.
