Symmons Industries LLD-20 Stem Assembly SY-5

Product Description

The SYMMONS INDUSTRIES LLD-20 is a stem assembly designed as a direct replacement component for SY-5 series faucet valve bodies. The stem assembly is the internal cartridge-style component that controls water flow and mix within a faucet or valve trim. It seats against the valve seat to start, stop, or regulate flow and is a common service part addressed during routine faucet rebuilds or leak repairs. This part is handled by licensed plumbers and experienced service technicians working on commercial and residential plumbing fixtures.

The LLD-20 stem assembly is intended for use in SY-5 series applications where the existing stem has worn, cracked, or failed to seat properly, resulting in drips or flow control issues. Installation typically occurs during scheduled maintenance or in response to a reported leak at the faucet. This is a direct-fit service replacement that restores original valve function without requiring full fixture replacement.

Key Features

• Direct-fit stem assembly for SY-5 series valve bodies
• Restores proper flow control and shutoff function
• OEM-style replacement for field repair and rebuild work

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing code requirements. Shut off the water supply and relieve line pressure before disassembling the valve body. Inspect the valve seat for wear or scoring before installing the new stem assembly, as a damaged seat will cause the replacement part to fail prematurely. Do not overtighten the stem during reassembly, as this can damage the stem threads or valve body.
