GENERAL INFORMATION:
Pipe Thread Sealant - Warranty is void when Teflon tape is used to seal pipe threads. This is because Teflon tape is a
friction reducing agent which allows customers to over-torque fittings. We recommend using a sealant that does not include
friction reducing agents i.e. Lead Plate.
Spool Information - All SDCF’s are built with Iosso plated spools to help prevent the spools from locking up when they are
in a corrosive environment. For highly corrosive environments, i.e. marine applications, we recommend using a stainless
steel spool. To order a valve with a stainless steel spool simply add “SS” to the end of the model code.
