Tapco G05-0357 Stem Bonnet

Product Description

The TAPCO G05-0357 is a stem bonnet designed for use in valve assemblies across plumbing, gas, and fluid control applications. The stem bonnet serves as the sealing and structural component that houses the valve stem, maintaining pressure integrity and preventing leakage at the valve body. Licensed plumbers and pipefitters install this type of component during valve repair, rebuild, or replacement service. It is a direct-fit service part intended to restore proper function to an existing valve assembly without requiring full valve replacement.

This stem bonnet is suited for residential and light commercial service environments where valve maintenance is performed on existing installations. It is commonly installed during preventive maintenance or emergency repair calls when a valve is found to be leaking at the stem. Trade professionals performing valve repacking or stem replacement will find this part applicable to SP-9SB valve configurations.

Key Features

• Provides a sealed housing for the valve stem in fluid and gas control applications
• Designed as a service replacement part for valve repair and rebuild work
• Supports pressure integrity at the stem-to-body junction
• Compact bonnet form factor suited for standard valve service

Compatibility

Designed as an OEM-style replacement stem bonnet for SP-9SB valve configurations. Verify valve model and stem dimensions before installation to confirm fitment.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter. Shut off all fluid or gas supply and relieve system pressure completely before disassembling the valve. Follow applicable local plumbing codes and IFGC requirements when servicing gas-side components. Do not overtighten the bonnet, as this can damage the stem seal or valve body threads.
