The SYMMONS INDUSTRIES SC-7 is a packing nut used to compress and retain valve packing material within a valve body assembly. Packing nuts create a watertight seal around the valve stem, preventing leaks at the stem-to-body junction. This component is commonly serviced during valve repair or repacking procedures and is installed by licensed plumbers and pipefitters working on commercial or residential water distribution systems.
The SC-7 packing nut is suited for valve repair and maintenance applications where the original nut is worn, damaged, or corroded. It is used in plumbing systems requiring a reliable stem seal, particularly during routine service calls or fixture overhaul work.
Designed as an OEM-style replacement packing nut for valve assemblies requiring a compatible SYMMONS INDUSTRIES service part.
Installation is typically performed by a licensed plumber. Shut off the water supply and relieve system pressure before disassembling the valve body. Use appropriate wrenches sized to the nut to avoid rounding the fitting. Follow local plumbing codes (IPC) for valve service and replacement procedures.
