Toro 120-4304 Stem Seal Valve Part

Product Description

The TORO 120-4304 is a stem seal designed for use in valve assemblies on Toro outdoor power and irrigation equipment. Stem seals prevent fluid or pressure loss at the valve stem interface, maintaining consistent flow control and preventing leaks during operation. This part is a direct replacement component used by irrigation technicians and outdoor power equipment service professionals to restore valve function without replacing the entire valve assembly. Proper sealing at the stem is critical to system performance and helps extend the service life of the surrounding valve components.

This stem seal is suited for repair and maintenance applications on Toro lawn and garden equipment where valve integrity has been compromised by wear, cracking, or fluid bypass at the stem. It is installed during valve rebuilds or targeted seal replacements as part of scheduled maintenance or field service calls.

Key Features

• Direct OEM-style replacement stem seal for Toro valve assemblies
• Restores proper sealing at the valve stem to prevent leaks and pressure loss
• Enables targeted valve repair without full assembly replacement
• Suited for use by irrigation and outdoor power equipment service technicians

Compatibility

Installation Notes

Stem seal replacement should be performed by a qualified technician familiar with valve disassembly procedures. Shut off all water supply or system pressure and relieve any residual pressure in the line before beginning work. Inspect the valve stem and seat for wear or damage before installing the new seal. Follow the equipment service manual for proper reassembly sequence and torque guidance specific to the valve model.
